Interplanting technique of corn and beans
The corn bean interplanting technology can increase the income, and the interplanting technology is a planting technique that many farmers are willing to implement. Here to explain the intercropping technology of corn beans.
First, corn cultivation management technology
Choose medium-ripe Danyu 13, 掖 single 4 and other varieties. The planting method should be planted in large and small rows, with a large row spacing of 80 cm, a small row spacing of 40 cm, and a plant spacing of 30 cm at the beginning of May.
Water and fertilizer management should be concentrated in the planting of the base fertilizer, pouring the bottom water to ensure a good bottom stalk after the corn is planted; the corn grows to the big bell mouth period, and the whole plant is sprayed with 20 kg of water and 20 kg per acre. In order to enhance the hardness of the straw; enter the brooding pollination period combined with the cultivating and cultivating soil, and apply 15 kg of ammonium phosphate and ammonium bicarbonate per acre according to the acupoint, which is beneficial to the corn grouting and the base fertilizer of the autumn bean horn; It was knocked out to improve the ventilation and light transmission conditions of the beans, and the two rows of corn with small row spacing were kidnapped by 4 crosses as the poles of the beans.
Second, autumn bean cultivation management technology
1. Choose varieties such as Chunfeng No. 4, Shuangfeng No. 2 and Qiuye L9 with strong growth potential, high yield, heat resistance, sputum resistance and disease resistance.
2, strict control of the sowing period, sowing too early and the corn symbiotic period correspondingly extended, is not conducive to growth. Sowing too late, the yield and benefits are reduced, and it is generally appropriate to plant in the early August and before August. The sowing method is as follows: directly on the hole at a distance of 15 cm from the root of the corn, 3 seeds per hole.
3. Field water and fertilizer management. Fertilization management should apply about 15 kg of urea per mu in the seedling stage to promote nutrition. The bean glutinous rice is about 1.5 meters long. It should be properly cultivated to facilitate drainage in the rainy season and prevent roots. It is strictly forbidden to water the flowers during the flowering period. When it is too dry, it can be poured with small water.
The intercropping of corn beans must be properly managed, and fertilization and soil cultivation should be arranged reasonably to promote high yield.
