First, the spring planting: Before planting, first of all, we will use the cultivating ship to deep plow till the last year's dug field, so that the soil can be planted. Every kind of farmer knows that the breeding season is clear and bright, and the annual calendar is 4-5 days in April. However, there is a big difference in the lunar calendar. For example, the Lunar New Year in 1939 was February 17, and the Lunar New Year in 1966 was March 19. Compared to the two dates, the difference was one month and two days. Therefore, I summed up an experience: In February, Ching Ming did not need to panic, and in March Ching Ming was busy. In other words, it will not matter if the Ching Ming period in February is delayed for ten days. In March, Ching Ming must be planted ten days in advance. This is the best date for selection. When the seedlings were planted, the field water could not be too deep to prevent it from being blown up by strong winds. After a week of deep water maintenance, it was 3-4 leaves and the time had already entered summer. Then it was summer. Tube period. Second, the summer tube: The main control of disinfection, fertilization, fight drugs, water control these four measures. 1. Disinfection: There are a large number of germs in the soil or in water. Failure to resolve them in time will affect the growth of lotus roots and lead to death. However, at the same time when using pesticides, it is necessary to pay attention to not using highly toxic pesticides. Disinfect with 100 kg of alum per acre. The occurrence of lotus root disease occurs in summer, and root rot is a common disease. After discovery, it must be pulled out in time, and 1 kilogram of thiophanate-methyl, 0.5 kilogram of green hen 2 and 30 kilograms of mixed soil are used to make medicine balls buried around the diseased bead. There is also a brown spot, which belongs to fungal airborne disease, which damages the leaves. In severe cases, it leaves the leaves withered and causes a reduction in yield. With 50% of the spores, 600 times of foliar spray is used to prevent and control, and phosphorus, potassium and calcium fertilizers are added. 2, fertilization: The main observation of growth, reasonable fertilization, generally grow to 3-4 pieces of loquat leaves, began to apply base fertilizer; grow to about 8 loquat leaves, began to top dressing; equal length to 8-13 loquat leaves began to scab. This time we must apply sufficient fertilizer to meet the standard of production. 3, fight drugs: wolfberry is a kind of delicate vegetable, there is a kind of insect in the soil, called the cricket, because it eat cricket, so we also call cricket, if you do not put it to death, it will affect the growth and quality of cricket Economic losses are inestimable. When quick lime is applied before the lotus root is planted and combined with the whole field, the lime application time should be about 15 days apart from the time of applying nitrogen fertilizer or superphosphate. If the interval is too short, it will reduce the effect of fertilizer. When lime is applied, put the field water first, and then put the pieces of quicklime in the open space where the lotus leaves are less. After it is melted, spread it with a shovel and mix it with the soil. Use 50 kg of quick lime per 667 square meters. 4. Water management: When entering the summer, it is the main period of lotus root growth. Every day, the field needs water, especially fertilized water. It must be guaranteed. The ancients said that: If fertilizers do not flow into fields, they will not make any profits if they flow into fields. First, they must do a good job of ridges, and secondly they must eliminate lobsters to maintain their normal growth. Third, the autumn harvest: In general, it is also possible to dig when the lotus blossoms are small, but this time it is not fully mature. When it was very hot, it was basically mature but it did not pollinate. The real maturity is the beginning of autumn, that is, the autumn harvest, and all the lotus roots can be harvested at the beginning of autumn. Fourth, winter protection: After the beginning of winter weather into the winter, when the lotus roots stop growing, but we must pay attention to maintenance. In deep snow, it is necessary to add deep water to prevent the lotus roots from freezing and affecting seedlings. Expert Reviews: Zhao Lixiang combined his own practical experience and attributed the lotus field management to the words “spring planting, summer planting, autumn harvesting, and wintering plantingâ€. It was explained one by one, concise and easy to understand and easy to remember. Although there is a need for substantial adjustments in the content, it is basically in line with local conditions, and it is highly operational and effective. There are some that need to be modified and added. I. Suggestions on "Spring Breeding" Two suggestions: (1) Do not introduce the clear date of the lunar calendar so as to avoid misunderstandings. In the middle and lower reaches of the Yangtze River, the planting of lotus roots is appropriate from late March to early April. It is appropriate to plant within 15 days before and after Qingming. If plastic sheds are used to cover cultivation, the planting period can be about 15 to 20 days earlier. (2) It is recommended that soil ploughing, basal fertilizer application, selection of improved varieties, quality of seed pods, amount of seed hoppers, and method of planting be increased. Second, the "Summer Pipeline" stresses emphasis on top dressing. Fertilizers generally require the first and second application of fertilization after 25 to 30 days and 55 to 60 days after planting, and 1500 kg of composted manure per acre, or 20 kg of compound fertilizer plus 15 kg of urea. For the purpose of harvesting the mature, dry lotus root, a third fertilizer is applied on the 75th to the 80th day after planting, and 10 kg of urea and potassium sulfate are applied per acre. I would also like to add that during the fertilization process in Putian, we should try to avoid scattering the fertilizer on the leaves and wash the fertilizer on the leaves in a timely manner to avoid damage to the leaves. In addition, the fight against drugs is not in the "summer tube" period. This point needs to be adjusted and should be merged with the "disinfection" content to prevent and control weeds. The pest control requirements for pests and diseases are highlighted and attention is paid to the use of pollution-free technologies. The main contents include: agricultural control, physical control, biological control, chemical control. Focus on the prevention and control of spirolachnite. When spongiosa occurs, it can be poured on a sunny day with copper sulfate solution once every 7 days for a total of 2 or 3 times. The amount of copper sulphate is determined according to the water depth. The amount of 0.5 gram of copper sulphate per 10 cm water depth is calculated for each mu of land. Third, the "Autumn Harvest" talked about pollination is wrong, because the lotus root products are asexual organs, do not pollinate. For lotus root harvesting, it is appropriate to start harvesting green lotus roots when the main loquats form 3-4 inflated sections. The time is 100-110 days after planting. When the leaves (the lotus leaves) begin to yellow, old and dry lotus roots are harvested. In addition to the rust-removing experience, the lotus leaf was cut in about 7 days in advance when it was harvested. Fourth, "Winter Insurance" alone is very good, emphasizing winter irrigation antifreeze.
