High-efficiency cultivation mode of rapeseed, peanut and waxy corn

In recent years, through the cultivation experiment, we have summed up a set of high-efficiency planting patterns suitable for the northern region, that is, the pure rapeseed in the same year, the intercropped peanuts intercropped with corn , and achieved good economic benefits. The cultivation techniques are now introduced as follows:

I. Import and export arrangements

The rapeseed was broadcast live in late October, and harvested in late May of the next year. After the rapeseed was simmered, the peanuts were planted as glutinous corn. In the middle of August, fresh corn stalks were harvested and peanuts were harvested in late September.

Second, the selection of varieties

1. Rapeseed should choose high-yield and disease-resistant varieties that meet the national high-quality rapeseed standards, such as Zhongyouza No.2, Zhongyouza No.10, Huayouza No.7, etc.

2. Peanuts choose medium-ripe, high-yield, disease-resistant varieties, such as Zhonghua No.9 and Luhua No.9.

3. The selection period of waxy corn is in line with the high yield and good quality under the local ecological climate conditions, such as Zhonghao No.1 and Lujing No.6, and considers the disease resistance and lodging resistance of the variety.

Third, soil preparation and fertilization

Choose fertile land with better irrigating conditions. After harvesting of the former sorghum crop, apply 3,000-4,000 kg of organic fertilizer per acre, 40 kg of superphosphate, 15 kg of urea, and 1 to 1.5 kg of boron fertilizer. soil. After the rapeseed is harvested in the end of May, 1000 kg of organic fertilizer per acre and 50 kg of high-concentration compound fertilizer are applied to the cultivated soil layer in combination with the tillage. The ridges are protected in time, the herbicide is sprayed after the ridge surface is finished, and the mulch is covered after spraying.

Fourth, sowing and planting

1. Rape. After the whole land is ditched, the rapeseed seeds are mixed into fine soil or fine sand, mixed and sown. After spraying the soil, 100% acetochlor EC 100 ml is sprayed on the whole water field for 2 days, which can effectively control the weed damage. After emergence, the seedlings should be planted 2 times, the first time in the 1 leaf stage, the second time in the 4 leaf stage, and the densely filled and vacant, leaving 10,000 to 12,000 plants per mu.

2. Peanuts. After the rapeseed is harvested in late May, 2 rows of peanuts are planted on the ridge surface, with a row spacing of 30 cm, a hole spacing of 15 to 17 cm, a planting of 0.9 million to 10,000 holes per acre, and 2 seeds per hole. Before sowing, the seeds were seeded with 25% carbendazim wettable powder to prevent seedling blight and anthrax.

3. Baked corn. Planting in stages in late May and early June, 1 row of waxy corn per 4 ridges of peanuts, plant spacing of 16 to 18 cm, planting about 1300 plants per acre to ensure that all seedlings are planted. After the emergence of corn, the soil is weeded, and the seedlings and seedlings are planted.

V. Field management

1. Rape. After the rapeseed is fixed, the seedling fertilizer should be applied in time. Generally, 10 kg of ammonium sulfate can be used for pouring, so that the seedlings can grow rapidly under the higher temperature conditions before the winter comes, and the strong seedlings can be overwintered. The rapeseed enters the fertilizer applied during the wintering period, mainly based on the farmhouse organic fertilizer, and is laid in the rows and filled with soil joints to achieve the purpose of antifreeze and heat preservation. In the second half of February of the next year, 40 to 50 kg of ammonium bicarbonate was applied per mu, and boron fertilizer was sprayed once in March. In the winter and in the spring, timely control of pests such as aphids, prevention and control of Sclerotium disease at the initial flowering stage, and timely harvest.

2. Peanuts. 10 to 12 days after sowing, it is necessary to clear the seedlings, followed by attention to cultivating the soil, control pests and diseases, timely control and prevention of prolonged, late foliar spray fertilizer to prevent premature aging, pay attention to the prevention and control of leaf spot disease.

3. Baked corn. 4 leaf stage seedlings, 5-6 leaves control water control fertilizer seedlings, 8-9 leaf stage light nitrogen fertilizer (10 to 15 kg of urea), large trumpet period (10 ~ 11 leaves) re-application of attacking fertilizer ( Apply 40-50 kg of urea per mu, increase the rate of ear formation, increase grain yield and increase production, and combine watering when topdressing. Because of its good quality and high pests and diseases, waxy corn should pay attention to the prevention and control of pests and diseases, and ensure the firmness and fullness.
