Fertilization (1) Panicle fertilizer. Generally in the big bell mouth re-application of nitrogen fertilizer, accounting for 50% of the total amount of topdressing, topdressing 30-40 kg of standard nitrogen fertilizer per acre. (2) Granular fertilizer. Generally account for about 10% of the total fertilizer, topdressing 10 kg of ammonium bicarbonate per acre. When fertilizing, open a 10-15 cm wide groove at a distance of 10 cm from the plant. The depth of the groove is 9-12 cm. After the fertilization in the trench, cover the soil with water. Pest control at the ear stage of corn borer can be used in the big bell mouth period, with 3% phoxim granules per acre 1.5-2 kg sand 5-6 kg, or with 50% phoxim EC formulated as 0.1% drug Amount of poisonous soil is spread evenly in the heart of corn. Control of corn leaf spot, sprayed with 50% carbendazim 500-800 times; control of corn rust and brown spot, at the beginning of the disease with 20% triadimefone EC 75-100 ml of water spray. Detasseling corn to help increase production. Detasseling can reduce nutrient consumption and promote the development of the ear; reduce plant height, improve ventilation and light conditions, enhance lodging resistance; overcome the phenomenon of flowering and disjointing of the male and female ear, is conducive to flowering meet, improve seed setting rate; reduce aphid damage. Going to master a good time, to go early to operate difficult, and tassels are too tender, easy to pull off or bring out the heart and leaves; too late to consume too much nutrients, increase production is not significant. The appropriate period for detasseling is that the tassel draws about one-third to one-half of the heart's leaves. At this time, it can be squeezed and can be pulled out with a little force. It is better to work from 9am to 4pm on sunny days so that the wound will heal easily. The number of emasculated plants generally accounts for about one-third of the total number of plants in the field, and no more than one-half of the total number. Generally, the number of detassels is emasculated. The two lines on the ground and the two plants in the ground should not be emasculated so as not to affect pollination. After detasseling, it is better to use combined pollination. Crop harvesters are accustomed to harvest when the corn husks turn yellow and the top of the grain becomes hard. According to many years of practice, the harvest is early and the weight of one thousand grains is low, which affects the output. The sign of mature corn should be the disappearance of the grain milk line. Harvest at this time, the weight of one thousand grains is high, and the yield can be increased by 8%-10% compared with the traditional harvest. On the same ear, the upper grain milk line formed first and disappeared earlier; the grain line of the grain at the base of the ear formed later and disappeared later. When the appropriate harvest period was determined, the lower grain milk line of the ear should prevail.
A urinalysis is a test of your urine. A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine.Clinical urine tests are various tests of urine for diagnostic purposes. A urinalysis is one of the most common methods of medical diagnosis. The word is a portmanteau of the words urine and analysis. Other tests are urine culture and urine electrolyte levels.
