Rational application of organic fertilizer to serve two purposes
Recently, Yang Huang, a farmer with a surname of Huang, was convicted of his 200-mu longan: nowadays, it is a critical period when longan is used for quick and effective autumn harvest. However, more than 100 yuan / pack of urea let him dilemma. If you go down with high costs, but do not know what will happen next year's market? Without fertilization, fruit tree harvest is certainly hopeless. Of course, it is not only the fruit grower in Yangchun but the millions of farmers in the province. Nowadays, it is the province of Xiaqiu that uses agricultural fertilizers for a relatively large period of time. The price of chemical fertilizers (mainly urea) that has remained high for more than two months has become a pain in the hearts of farmers in our province. How can we reduce the cost of fertilizers and increase the use of fertilizers? A number of soil and fertilizer experts from Provincial Fertilizer Association, South China Agricultural University and other organizations interviewed by this reporter suggested that changing the habits of the past and indiscriminate application of nitrogen fertilizers and rational application of organic fertilizers would be a good way to solve the problem. Partial application of nitrogen fertilizer increased the amount of fertilizer used South China Agricultural University soil fertilizer expert You Zhi. According to the professor, developed countries pay attention to scientific fertilization, and the nitrogen utilization rate reaches 40% or even 50%. However, because farmers in China have the habit of reapplying and applying nitrogenous fertilizers, the utility of nitrogen fertilizers has generally declined, and the utilization rate of nitrogen has been low. About 30%. This evil has been exposed in many areas. According to many farmers, the lack of application of organic fertilizer will increase the "appetite" of cultivated land: 100 kg in the first year, 110 pounds in the second year, and 130 pounds in the third year. In order to ensure equal production, the cost of 30 pounds of fertilizer is increased in vain! Fertilizer experts explained that the main reason for this phenomenon is that the use of chemical fertilizers causes the effective amount of soil microelements to continuously decrease. Because the normal growth of crops, in addition to absorbing nitrogen, phosphorus, potassium nutrients, but also absorb calcium, magnesium, sulfur, iron, manganese, boron, zinc and other trace elements, if a certain element can not meet, it will affect Its growth. For example, litchi, longan, citrus, etc., which are currently planted in our province, have suffered from apparent deficiency of nutrients in many orchards after several consecutive harvests. Farmers have mistakenly thought that they lacked fertilizer, and then increased the amount of fertilizers to increase the cost. , And the effect is not ideal. Nowadays, the price of nitrogenous fertilizers soars, and compound fertilizers will rise. This kind of waste will further increase the cost of fertilization, which will undoubtedly make the farmers worse. Professor You You believes that under the influence of the current dual factors, farmers must change the habit of reapplying and applying nitrogenous fertilizers, promote balanced fertilization, and apply organic fertilizers to crops. For example, half of the fertilizer will be used to buy organic fertilizers or organic compound fertilizers, which is much better than applying chemical fertilizers. Commodity organic fertilizer meets the needs of the development of the situation The Provincial Fertilizer Association Secretary-General Zeng Sijian Senior agronomist believes that the application of chemical fertilizer is the need for agricultural development and agricultural production. When agriculture enters a new stage of development, it must adhere to the combination of organic and inorganic resources, land use and cultivation. The principle of combining land with land, the proper use of organic fertilizer can change the single phenomenon of soil microorganisms, so as to achieve a multiplier effect. Nowadays, with the development of economy, farmers pay more and more attention to production efficiency, economic benefits, and the convenience and hygiene of fertilization. The traditional farmer's manufactory is hand-built, self-produced, labor-intensive, labor-intensive, and odor-spoken. The farmers spread "there's no need for black, no need to use dry, no wet," and "better than a burden." "And so on, is to reflect the modern farmers' demand for organic fertilizer. In addition, in recent years, the rapid development of China's green food and organic agriculture has contributed to the development of organic fertilizers. Therefore, the emergence of organic fertilizers has responded to the needs of the development of the situation. According to industry estimates, the proportion of organic fertilizer used in our province will increase in the next few years. Organic fertilizer compound economic benefits and ease of application It is understood that in recent years the province's organic fertilizer manufacturers continue to increase, organic fertilizer, organic compound fertilizer products emerging, farmers can buy directly to the fertilizer shop, and these fertilizer prices are mostly about half of fertilizer. It is said that the use of high-quality commercial organic fertilizer 200-300 pounds of acres, the effect can be equivalent to 3000-5000 kg farmyard fertilizer, both economical and convenient to use. “It is not chemical fertilizer that is better than chemical fertilizer; it is not peanut bran, and it is better than peanut bran.†A seedless yellow-peel grower in Yunfu City has deep feelings. Earlier this year, he bought a 2 ton organic compound fertilizer on the yellow bark with a mentality of trying, and compared it with the yellow bark which used the manure. When mature harvest was conducted in July, it was found that the effect of applying organic compound fertilizer was significantly better than that of farmyard manure: the yellow bark was full, uniform in size, and thick and fleshy, which was popular with fruit vendors. The difference in the effect of the two fertilizers has puzzled the fruit farmer. Associate Professor Xie Lichang, a soil fertilizer expert at South China Agricultural University, said that the characteristics of inorganic fertilizers are fast, the characteristics of organic fertilizers are stable, organic and inorganic ingredients are combined, and fertilizer efficiency can achieve the advantages of being both fast and stable, and at the same time creating high yields and supplementing organic matter. . According to Professor Liao Zongwen, a soil and fertilizer expert from South China Agricultural University, the organic and inorganic components of organic compound fertilizers have the same characteristics of being both at the same time and at the same time. The balance between organic and inorganic materials has been achieved, and fertilizers have been used to avoid the disadvantages of chemical fertilizers. Liangtian Lvxing Loktian's three major manufacturers have rich products. As the country's first organic-inorganic compound fertilizer manufacturer, Guangzhou Liangtian Fertilizer Co., Ltd., its Kangbao brand six series of organic-inorganic compound fertilizer products sell well all over the country. At the same time, the company's first "use of industrial and agricultural waste development and development of multi-functional organic-inorganic compound fertilizer (controlled release fertilizer)" plays an important role in the reuse of waste resources, maintaining ecological balance, and protecting the environment. Following the successful launch of organic fertilizers and organic-inorganic compound fertilizers, Yunfu Lvxing Compound Fertilizer Co., Ltd. recently introduced a liquid organic compound fertilizer that can be applied by spraying and foliar spraying. It can be said to be organic fertilizer and organic compound fertilizer products. Promote. Last year, Chen Guinian, a Yunfu Shatang orange grower, used this fertilizer to enjoy a bumper harvest and improved quality. His experience was broadcast on China Central Television's Spark Technology section and the audience responded strongly. The Guangzhou LeTian Eco-friendly Organic Fertilizer Plant, a rising star, has produced high-tech bio-active organic fertilizers with its core technology of “nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-releasing bacteriaâ€. It has been rapidly promoted in Guangzhou and surrounding areas in less than one year. Applications are popular among vegetable farmers who grow leafy vegetables, melon beans, and potatoes. Especially applied to sweet corn, the stalks are thick, the leaves are thick, the disease resistance is enhanced, and the yield and quality are improved obviously. White Organic Fertilizers Are Most Bad Goods At present, due to the fact that domestic organic fertilizers are in the initial stage of development and the quality of products is uneven, farmers will buy some inferior organic fertilizers from time to time. The effect is not obvious. For this reason, industry insiders who are familiar with the market have reminded that if you do not understand the true and false consumers, you can look at the appearance of fertilizers when you buy them, because the colors of organic fertilizers and organic compound fertilizers are mostly black, and if they are white, most of them have quality. Questions need to be taken care not to be deceived. In addition, organic fertilizers of different raw materials have different fertilizer effects. The relevant experts from the Provincial Soil and Fertilizer Terminal stated that according to the current commodity organic fertilizer standards, the requirement for organic matter to reach 30% can be listed, and different manufacturers may use different raw materials, such as chicken manure, pig manure, peat soil, bagasse, furfural residue, wood chips , straw and other production of different organic fertilizers. However, relevant sources revealed that although organic matter content is 30%, using chicken manure as raw material is much better than using wood chips as raw material. It is understood that at present, the organic fertilizers produced by chicken manure in our province mainly include Yunfu Lvxing Organic Fertilizer, Guangzhou Letian Organic Fertilizer, Yuexing Organic Fertilizer, Delong Organic Fertilizer, Guangzhou Likang Organic Fertilizer and Kangbao Organic Fertilizer. and many more. According to reports, individual manufacturers of unscrupulous organic fertilizers often use fakes to mark chicken dung, peanut bran and other raw materials on the packaging, but the price is lower than similar high-quality products. Farmers should not be greedy and cheap to buy because peanut bran is Tons of more than 2000 yuan, use it as a raw material to produce organic fertilizer, the cost is obvious.
