First, crop arrangements and planting specifications. Crop arrangement: peanut (cover film spring sowing), tomato (intercropping in peanuts, or cabbage), Chinese cabbage (planted after peanut harvest); planting specifications: peanut ridge planting, ridge distance 85 cm, 2 rows per ridge . The small row spacing is 30 cm, the large row spacing is 55 cm, and the pitch is 16 cm. The tomato is transplanted in the large row of peanuts, the plant spacing is 30 cm, and the cabbage is 667 square meters, which is 2,083.
Second, choose the right variety. Peanuts use special early-maturing and high-yield peanuts "Ping degree 204", tomatoes use early-maturing high-yield varieties 72-69, and Chinese cabbages use late-maturing high-yield varieties 83-24.
Third, the whole land, the application of fertilizer. With this cultivation method, it is necessary to select a fertile land with hydration conditions. It is best to carry out deep winter ploughing or deep ploughing years ago, the depth is to break the "plow bottom" degree, and combined with winter ploughing to apply some soil fertilizer. In the early spring, after the soil was frozen, the ridge was preserved early, and then the ridge was ridged. The 667 square meters concentrated application of soil fertilizer 4000~5000 kg, ammonium bicarbonate 20~30 kg, phosphate fertilizer 30~40 kg, potassium fertilizer 10~15 kg.
Fourth, staged sowing, fine management. Peanuts are sown in early April. First, they are separated by a narrow groove of about 3 cm at a distance of 30 cm on the ridge. When the lyrics are poor, they should be watered for sputum. Then, they should be sown at a distance of 16 cm. The seeds of the buds were then planted with 0.5 kg of "812" fertilizer. Finally, the soil is stepped on, and the surface is covered. Spray acetochlor on the face and cover the mulch. About 8 days after sowing, 3 cm thick soil was pressed on the mulching film to facilitate the emergence of peanut rupture. After the seedlings, clear the ridges to expose the peanut leaves to the membrane surface. In the needle-down period of peanuts, the titanium is sprayed twice for fertilizer, with an interval of 10 to 12 days. About 35 days after the initial flowering, a 1500×10-6 paclobutrazol solution was sprayed on the leaf surface. After mid-July, if it rains, it should be sprayed 400~600 times of the mancozeb solution after the rain. Tomatoes can be planted in Yangshuo in the middle and late February, and seedlings will be planted in late March. In mid-April, soil will be transplanted into the peanut line. Watering should be done in time after planting, and timely drafting should be carried out. When the second inflorescence of the tomato grows 2 true leaves, the top of the heart is beaten, leaving only 2 inflorescences per plant, leaving 2 to 3 fruits per inflorescence. After hitting the top of the heart, pay attention to erasing the side buds in time. When the fruit begins to expand, 667 square meters is topdressed with 10 kilograms of urea and watered. In late June, the tomatoes will mature. If the peanuts are harvested at the end of July or early August and sold as fresh fruit, then the cabbage can be broadcast after the peanuts are harvested (or spinach can also be grown). If the peanuts are harvested after normal maturity, the cabbage seedlings should be bred in early August, and the cabbage seedlings should be transplanted in the field before and after August 25. The planting density and management of Chinese cabbage is the same as that of pure Chinese cabbage.
