First, crop arrangements and planting specifications. Crop Arrangement: Peanuts (covered in spring filming), Tomatoes (interplanted in peanuts, but also cabbage), Chinese cabbage (pears after harvest); Planting specifications: Peanut ridging, ridge spacing 85 cm, 2 rows per ridge . Small row spacing is 30 centimeters, large row spacing is 55 centimeters, and pier spacing is 16 centimeters; tomato is transplanted in rows of peanuts, plant spacing is 30 centimeters, and cabbage is 2,083 square meters.
Second, choose the right variety. Peanut chooses special precooked and high-yielding large-peanut “flatness 204â€, tomato uses early-maturing high-product variety 72-69, and Chinese cabbage uses late-maturing high-product variety 83-24.
Third, make a good, full of fertilizer. With this cultivation method, it is necessary to select a fertile land with watering conditions. It was better to perform deep winter plowing or deep plowing years ago, with the depth to break the “plow bottom layer†as a degree, combined with winter tillage to spread part of the soil manure. In early spring, as soon as the soil is thawed, the land is ridged and ridiculed as soon as possible. After ridging, 667 m2 of concentrated soil is mixed with 4000-5000 kg of compost, 20-30 kg of ammonium bicarbonate, 30-40 kg of phosphate fertilizer, and 10-15 kg of potash.
Fourth, sowing, fine management. Peanuts were planted in early April. The sloping groove was about 30 cm deep and 3 cm deep at the ridge. When the waterlogging situation was poor, watering was used to make leeches. Then, the seeds were planted at a distance of 16 cm. The seeds of the buds, then 667 square meters were covered with 0.5 kg of "812" medicinal fertilizer. Finally, the earth-covered soil is solid and flat. Acetochlor was sprayed on the surface and the film was covered. About 8 days after sowing, 3 cm thick soil was pressed on the mulching film to facilitate the emergence of broken peanuts. After the seedlings were established, the ridges were cleared to expose the peanut cotyledons to the membrane surface. In the period of peanuts under the needle, two shots of titanium are given, with intervals of 10 to 12 days. About 35 days after flowering, paclobutrazol solution of 150010-6 was sprayed on the leaves. After mid-July, in the event of rain, 400 to 600 times mancozeb solution should be sprayed after rain. Tomatoes can be planted in Yangshuo in late February and seedlings can be planted in late March. The seedlings can be planted in late March. In mid-April, they are transplanted with soil to peanuts. After planting, it should be watered in time, and it should be scheduled in due course. When the tomato grows 2 true leaves above the 2nd inflorescence, the head is removed, leaving only 2 inflorescences per plant and 2 to 3 fruits per inflorescence. After taking heart, you should pay attention to wipe the side buds in time. When the fruit begins to swell, 667 square meters of topdressing 10 kg of urea and pouring enough water. In late June, tomatoes can mature. If peanuts are harvested at the end of July or early August and sold as fresh fruit, then cabbage can be broadcast directly after the peanut is harvested (spinach can also be grown). If peanuts are harvested after normal maturity, cabbage seedlings need to be planted in early August. Before and after August 25, cabbage seedlings will be transplanted into Daejeon. Chinese cabbage planting density and management with pure Chinese cabbage.
