With the increase of the planting area of ​​vegetable peas, the majority of vegetable growers chose summer maize corn stalks as the scaffold for corn-vegetable pea circular agricultural cultivation techniques. The main technical points are as follows:
First, the corn cultivation techniques
1. Variety selection: Choose corn varieties with strong resistance, stout stalks, well-developed root systems, and high yield and quality.
2. Planting specifications: The sowing date is in early June, and the width is 0. 8 meters, two rows of plant spacing 0. 25 meters until the corn harvest in late September, leaving 1. 7 meters of orange stalks.
3, field management: In the growing period of corn, in addition to do a good job of pest control, but also should be carried out two fertilization and earthing, that is, seedling period: 35 to 40 days of seedlings combined fertilization and fertilization soil once, apply corn special compound fertilizer 50 ?/mu; Twenty-half urea at the mouth of the trumpet, 50 grams/mu of calcium, and soil once, keep corn stalks green when harvested.
Second, vegetable pea cultivation techniques
1. Select good seeds and timely sowing: Select the local purple flower pea pod species. From late September to early October along the side of the corn stalks. Sown at 1 meter, 2 to 3 capsules per pond.
2, fertilizer and water management and harvesting methods: After the planting of peas, if the soil moisture is suitable, there is no need for irrigation before the flowering period within one month to reduce the occurrence of root rot; if the soil is dry when planting, the humidity is insufficient, Only horse race water can be released, and irrigation can be arranged. One month after emergence, the bean vines will be cleared on the orange stalks. After that, the vines will grow indefinitely and then be cleaned with straw ropes 2 or 3 times. The fertilization is usually carried out after the first irrigation of vines. / Acre, potassium sulfate 10% / acre. The peas in the restaurant are mainly chyme, and there is no need for full grain. As long as the grains begin to form, the seed marks can be seen under the light, and the pods can be harvested in dark green and wide straight. 25 to 30 days after the start of harvesting, combined irrigation can make up 25 //mu of ammonium bicarbonate or 10 //mu of urea, and can also be sprayed with 0.3% potassium dihydrogen phosphate to provide plant nutrients. General mu production 1000-1500?/mu.
3. Pest Control: The major pests and diseases of peas in vegetable oysters are root rot. It mainly adopts rational rotation and timely irrigation and drainage measures. If necessary, 70% of the enemy can also be used to disinfect the soil. In the middle and late stage, it is mainly powdery mildew, which is treated with triadimefon, thiophanate-methyl, or Burritt alternate spray. Insect pests are supplemented by Liriomyza sativae, Drosophila domestica, and aphids. Liriomyza was used for the control of avermectin pesticides; aphids were controlled with imidacloprid, stilbene, or pyridoxine. Used alternately, the effect is better.
Third, economic analysis
1. The use of corn stalks as a vegetable pea support, 4000 stalks of 4,000 stalks are wood poles, and the wood poles are calculated at 0.3 yuan per root. The cost of the wood poles is 1200 yuan, which can be used for three years. Yuan, so the corn stalks increase efficiency by 400 yuan/mu.
2. The corn field block is 15 days higher than the paddy field block price in the morning. The price per kilogram will increase by 0.6 yuan/ton, and the city's output will account for 30% of the total output, which will be 400 yuan, and the value will increase by 240 yuan.
3. Rice fields cost 100 yuan more for cattle than corn fields, and therefore they cost 100 yuan.
4. The 500-meter rice coin is 1,500 yuan per mu, the corn coin is 750 yuan and the corn field is 1350 yuan, and the corn field is 150 yuan in the paddy field. However, paddy field must have good fertilizer and water conditions to achieve this level of output.
To sum up, the recycling agriculture technology using corn stalks as a vegetable pea support can at least save 590 yuan/mu. The promotion of this technology in the project of science and technology home-based project is very significant in terms of economic, ecological and social benefits.
