[0027] A, soil selection and site preparation: select fertile land, and the plots with convenient irrigation and drainage conditions are used as seedling beds and field planting beds; the seedling beds are 1 meter wide, do not apply basal fertilizers during site preparation, and turn 30 centimeters deep, and use claw ditch to block leveling , and then block leveling and finalizing; the planting plot should be dry and whole, and the dry plot should be ditched and watered, and 5000 kg of farmyard manure should be applied per mu, with 20 kg of biological fertilizer, 20 kg of urea, 150 kg of superphosphate, and 35 kg of potassium sulfate. kg, the loam soil is fully mixed evenly, the border soil is loose and solid, and the border surface is smooth;
[0028] B. Sowing seedlings: The seedling time of chives and chives is about April 10 every year. Before seedlings, the prepared seedlings will be watered thoroughly, and the seeds will be evenly mixed with carbendazim, and then 5% phoxi...
Embodiment 2
[0033] A. After harvesting in Example 1, use ground spraying after harvesting, that is, at the adult stage, spread 2.5% trichlorfon powder along the ridge, and spread 2 to 2.6 kilograms per mu, or at 9:00 am to 11:00 am. When spraying 40% phoxim emulsifiable concentrate 1000 times;
[0034] B. The weeds in the field should be cleaned up in time, so as to remove them early and frequently, and keep the border free of weeds. When the leek seedlings grow to 7-10cm, the mixed fertilizer with the following weight ratio should be topdressed once: urea 15 kg , 5 kg of boric acid, 2 kg of molybdenum acid, 17 kg of white stone powder, 18 kg of ammonium urea nitrogen fertilizer, 10 kg of polypeptide urea, 12 kg of ammonium bicarbonate, 0.2 kg of trace elements, of which trace elements include zinc, iron, manganese, copper, about 15 kg Topdressing 1 time after 1 day, cover the grass curtain and cut green, cover the grass curtain after topdressing, avoid sunlight; Arrange the grass tails ne...
Embodiment 3
[0038] A. After harvesting in Example 2, use ground spraying after harvesting, that is, in the adult stage, spread 2.5% trichlorfon powder along the ridge, and spread 2 to 2.6 kilograms per mu, or at 9:00 am to 11:00 am. When spraying 40% phoxim emulsifiable concentrate 1000 times;
[0039] B. Fertilizer and water management and soil cultivation: Fertilize and water once every 20 days. Fertilization is 25-35Kg of selenium fertilizer and nitrogen fertilizer per mu, and keep the soil moisture content at 70-80% during the period;
[0040] C. Harvesting: Harvest after the leek seedlings are mature, the harvesting days are 15-18 days, and keep the leek seedlings with a length of 2-3 cm above the root to wait for the growth of the next cycle.
[0041] Pest control methods:
[0042] 1. Botrytis: Botrytis mainly damages the leaves. When a small number of plants are found to be sick, spray with 50% saccharin or 50% chlorpyrin 1000 times, or 50% carbendazim WP 500 Double liquid contro...
