è è is one of the main economic crops in Zhendong District of Tengyue Town. The annual planting area is about 5,000 mu and the average yield per mu is about 1500kg. The main cultivation techniques are:
First, use fine varieties
Should choose the disease-resistant and high-yielding Baoshan?
II. Cultivation
1, fertilize the field. Before the seedlings, per acre of seedlings, 1,000 kg of cooked manure and 15 kg of Western fertilizer were used as base fertilizer.
2, nursery. Take a step-by-step method of breeding 10 kg per acre. Seedlings are planted on the vegetable garden for the first time around April 5. They will be planted one after another on a square meter of ground and watered for 2-3 days. When the seedlings grow to 13-15cm, they are pulled into the field and cultivated a seedling.
3, Putian top dressing. The seedlings in Putian grow up to 15-20cm per mu of paddy field topdressing urea 10kg, calcium 15kg.
Third, Daejeon preparation
1. Soil selection. It is advisable to choose a soil with good water source conditions, good water retention performance, convenient drainage and irrigation, and loose and fertile soil. Plough depth is 20cm, and soil acid reduction is 6.5-7.5.
2, the whole field. In the 15 days to 20 days before planting, the whole field is required to be two plows and two plows.
3. Apply base fertilizer before transplanting. Apply 1000-1500kg of organic fertilizer per acre, 40kg of Atlantic compound fertilizer
IV. Planting in Daejeon
1, planting time. Planting at the end of June and early July will not be able to surpass the agency at the latest.
2, planting density. Plant spacing 50cm40cm, each hole planted a bundle of 3-4 natural meristems of phylloidal, planting 2500-3000 per acre, planting depth to the roots of the lower part of the phyllo-cymes into the mud to live, about 5-6cm.
Third, strengthen field fertilization, strengthen water slurry management
1, top dressing. Secondary administration. The first time after transplanting and returning green, it will be applied around July 30, with urea 5-8kg per acre or fecal urine 400-500kg for decomposing humans; the second time is a relay fertilizer with a large maggot, combined with manual weeding at 8 On the 30th of the month, the color of the aboveground phyllospora is deepened, and the central strain of the meristem strain begins to be applied when the stem is pumped. The urea is 8-10kg per acre, potassium is 5kg, and calcium is 10kg.
2, water slurry management. After transplanting, planting water is 5-7cm deep to promote greening. After returning green, keep the shallow water layer 2-3cm deep and promote ramets. Beginning in mid-September, keep the depth of field about 10cm to suppress excessive ramets, early scabs, and promote bulb enlargement. Water was cut off in mid-October. In early December, water was drained around Daejeon to facilitate digging.
3, harvest. The next year can be excavated in January, can receive early March.
