Sticky corn small green pepper intercropping technology
Small green pepper mixed with sticky corn can stagger the sowing date and planting period, increase the effective leaf area index per unit area, so as to make full use of time and space to improve light energy and land utilization. Because small green pepper is a crop that is not resistant to high temperature and strong light, its physiological function is blocked under high temperature and strong light, and its resistance is reduced, which is conducive to the invasion and proliferation of viruses, so it is easy to develop; at the same time, small green pepper is also a rain-tolerant crop in the rainy season. Fungal and bacterial diseases are often prone to occur, reducing plant resistance and inducing the occurrence of viruses. By using sticky corn and small green pepper intercropping, it can play the role of high corn as a small green pepper to shade and reduce temperature. Generally, every 667 square meters can produce fresh green peppers 1100 ~ 1200 kg, sticky corn fresh ears 2800 ~ 3000 spikes, the output value can reach 1800 ~ 2000 yuan, 667 square meters of net income more than 1,500 yuan. The cultivation techniques are as follows.
Site preparation
For the sowing plots, first take the net roots, the autumn ridges or the spring top ridges, combined with the ground preparation of 667 square meters of high-quality farmyard manure 2 to 3 cubic meters for the base fertilizer, the ridge distance of 70 cm, timely suppression after the completion of the site, to reach Sowing status.
2. Live small green pepper
Directly broadcast small green pepper varieties in early May. The sowing method is to use the back ridge and other equipment to flatten the ridge surface, and draw three parallel grooves on the top. The ditch is 3 cm deep and the distance between the ditch is 7 cm. When planting, the small green pepper seeds are scattered in the ditch, 667 square meters. 1250 grams of seed, the chemical fertilizer is scattered in the middle ditch, 667 square meters with diammonium 10 kg, potassium sulfate fertilizer 5 kg, after the soil cover soil, step on the lattice to protect. Generally, it can be emerged in mid-May, and the field management is strengthened after emergence. When the seedling grows 2 leaves and 1 heart, the seedlings are planted, and the seedlings are kept. The plant spacing is 15 cm. During the growth of small green peppers, the management of pests and shovel is strengthened.
3. Sowing sticky corn
The selection of the varieties with the growth period of less than 110 days and the green corn ear to be marketed in about 85 days is generally better. Soaking seeds and germination on June 20. Seeding was carried out before June 25, and 1.5 kg was used for 667 square meters. At the time of sowing, plan to plant each of the 2 plants in the small green pepper plant, with a distance of 33 cm and a depth of 5 cm. After fertilization, the water was poured, and after the water was infiltrated, 2 to 3 sticky buds were planted and covered with soil. 667 square meters of application of fertilizer diammonium 10 kg, after the emergence of seedlings to strengthen field management, first and time seedlings, seedlings 2 leaves 1 heart time seedlings each retention of 1 strong seedlings. The second is to shovel in time to eliminate weeds in the field. The third is rational fertilization, and the corn is fertilized twice in the growing season. The first time was after the seedlings, the urea was chased around July 15th, the amount of 667 square meters was 10 kilograms, the second top dressing was in the middle of August, and the 667 square meters was 1 kilogram of urea.
