Rape, Peanut and Waxy Corn Efficient Cultivation Model
In recent years, through cultivation experiments, we have summed up a set of efficient planting models suitable for the northern regions, namely the pure rapeseeds and the intercropping peanuts for waxy corn, which have achieved good economic benefits. Now its cultivation techniques are described as follows: First, the cornucopia is arranged to harvest rapeseed in late October and harvest in the second half of next year. After the rapeseed cultivar is harvested, the peanuts are intercropped with waxy corn. In mid-August, harvested fresh corn on the market and harvested in late September. Second, the selection of species 1. Rape should meet the national high-quality rapeseed standards of high-yield, disease-resistant varieties, such as Zhongyouza No. 2, Zhongyouza No. 10, Huayouza 7 and so on. 2. Peanut choose medium-ripening, high-yield and disease-resistant varieties, such as Zhonghua No.9 and Luhua No.9. 3. The selection period of Waxy Maize is in line with the high yield and good quality under the local eco-climatic conditions, such as Zhongkai No. 1 and Lulu No. 6, etc., taking into account the disease resistance and lodging resistance of the varieties. Third, the fertilization to choose the fertility conditions better irrigated land, after the harvest of the first crop, the application of organic fertilizer per acre 3000 to 4000 kg, 40 kg of superphosphate, 15 kg of urea, boron 1 ~ l. 5 kg, combined Ploughing into the soil. After the harvest of rape in late May, apply 1000 kg of organic fertilizer and 50 kg of high-concentration compound fertilizer per acre. Apply the ploughing to the ploughing soil layer to ensure timely ridging and ridging, and spray the herbicide after the ridge surface is in good condition, covering the film after spraying. Fourth, sowing and planting 1. Rape. After a good land ditching, rapeseed seeds are mixed into fine soil or fine sand, mixed well and sowed. After 2 days of soil covering, 50% acetochlor EC 100 ml is sprayed on the water, which can effectively control weed damage. After the emergence of seedlings to 2 times, the first time in the 1 leaf stage, the second time in the 4 leaf stage, to make up for shortages, leaving 10,000 to 12,000 plants per acre. 2. Peanuts. After the harvest of rape in late May, two rows of peanuts were planted on the ridge surface, with a spacing of 30 cm, a hole spacing of 15-17 cm, and planting of 9000-10,000 holes per acre with 2 seeds per hole. The seeds were sown with 25% carbendazim WP before seeding to prevent seedling blight and anthracnose. 3. Waxy corn. In late May and early June, sowing, each row of 4 ridges between peanuts for a line of waxy corn, plant spacing 16 to 18 cm, planting about 1300 per acre, to ensure that the whole seedlings broadcast. After corn emerged, weeding, weeding, and seedlings were used for weeding. V. Field Management 1. Rape. After the seedlings of rapeseed, the seedlings should be topped up in time, and generally 10 kg of ammonium sulfate can be used for pouring water to facilitate the seedlings to grow rapidly under the higher temperature conditions before the onset of winter and reach the strong seedlings for winter. The fertilizer used during the overwintering period of rapeseeds is mainly farm organic fertilizers, spreads between rows, fills the earth seams, and achieves the purpose of freezing and heat preservation. In late February of the following year, 40-50 kg of ammonium bicarbonate was applied per acre, and boron fertilizer was applied once in March. Pre-winter and early spring control of insect pests, such as locusts, early flowering control of Sclerotinia, and timely harvest. 2. Peanuts. After 10 to 12 days after sowing, it is necessary to clear seedlings and seedlings, followed by attention to cultivating soil, to prevent and control diseases and insect pests, timely control and prevention of prosperous growth, and late spraying of fertilizers to prevent premature aging, and to prevent and treat leaf spot disease. 3. Waxy corn. 4 leaf stage Dingmiao, 5 to 6 leaf stage water control fertilizer seedlings, 8 to 9 leaf stage light recovery nitrogen fertilizer (mu urea 10 to 15 kg), large bell mouth period (10 to 11 leaves) heavy reaping and tapping fertilizer ( Mushi 40 ~ 50 kg urea) to improve the spike rate, increase grain production, when combined with watering fertilizer. Waxy corn has good quality and has many diseases and insect pests. It is necessary to pay attention to the prevention and control of pests and diseases during production to ensure that it is full and full.
