Spray vinegar on the vegetables, can improve the utilization of light energy, improve yield, improve quality. Vegetables especially love to eat "acid".
Tomato and fruit vegetables from 1 to 2 days after planting, every 7 to 10 days spraying, even spraying 3 to 5 times 300 times liquid vinegar solution, tomatoes and peppers have a better effect on the prevention of virus disease, tomatoes can increase yield by 10% to 34%, chili peppers, eggplants can increase yields by more than 8%.
Cucumber blossom, fruit before, mu with vinegar 0.5 kg, 50 kg of water spraying, can increase yield 18% to 20%. When cabbage is 5 leaves, use 200 times vinegar water solution, spray 1 time per week, spray 4 times in a row, it can increase the yield by more than 10%, and it can effectively prevent soft rot disease.
2, sweet
Sugar in vegetables can be used as foliar fertilizer, but also can be used to control some diseases.
Spraying 0.2% sugar solution in cucumber seedlings can make seedlings thick and strong, and enhance the plant's resistance to downy mildew. Sprayed 1 time during the melon formation period, the melon strips taste especially good. Spraying cucumbers with 1% sugar solution can also control virus diseases.
3, fertilization
To fertilize and water the vegetables, these seem very simple things, in the Sichuan Academy of Agricultural Sciences vegetable experts Li Zhi seems not simple. He was interviewed by the reporter, introduced the vegetable fertilizer technology.
Basic fertilizer must be rotted. Base fertilizer is generally stable fertilizer, compost and other late-effective farm organic fertilizer. In the vegetable sowing or planting before applying into the soil, in order to supply the needs of the continuous growth of vegetables. These farmyard fertilizers not only contain a variety of elements needed by vegetables, but also supply the soil with a large amount of organic matter, can be very good to improve the soil.
4, reproduction methods
Vegetable fertility is always throughout the nutritional growth and reproductive growth. Vegetables if there is no large nutrient area, fruit growth; if the nutrient growth is too strong, is bound to inhibit fruit expansion. Artificial use of water, fertilizer, gas, light, temperature, medicine to control and promote, adjust the fertility relationship between the two, seems particularly important.
Pregnant buds in the neutral (10-12 hours) sunshine, fruit performance growth fast. Early maturing varieties under 12-14 hours of sunlight, flowering faster; late maturing varieties under 10 hours of light, flowering fast . In neon, daylight, red light irradiation, bud and fruit growth fast. Fruit gestation period, accelerated absorption of nitrogen, carbon and phosphorus; expansion period, the greater need for carbon and potassium, the old ripe period, the absorption of phosphorus is more.
5, irrigation
China's northern general high temperature and drought, less rainfall, high ground temperature. And in vegetable cultivation, there is no harvest lies in the water. Therefore, the reasonable irrigation of vegetables is particularly important.
Irrigation according to the type and characteristics of vegetables. For cabbage, kale, cucumber and other shallow root system and leaf area of the species, to frequent irrigation, to the bed surface is not dry as a principle.
Tomato, eggplant, beans and other vegetables, its root system is deep and large leaf area, should ensure that the bed surface "see dry and wet", the fast-growing vegetables should maintain fertilizer and water. Fruit and vegetable vegetables to avoid mom flower period (the first flower period) watering, to water pods do not water flowers. Watermelon, melon, pumpkin, carrots, etc., in the sowing or planting can not lack of water, generally first wet and then dry.
