1. Sour
Spraying vinegar on vegetables can improve light energy utilization, increase yield and 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, can increase the yield by more than 10%, and 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, old maturity, 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. Cabbage, kale, cucumber and other types of shallow root system and large leaf area, 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. For watermelon, melon, pumpkin, carrots, etc., in the sowing or planting can not lack of water, generally first wet and then dry.
Extended information
The types of vegetables are leafy vegetables, roots and tubers, teeth and seedlings, fruits and vegetables, mushrooms, melons and so on.
According to incomplete statistics, there are more than one hundred kinds of vegetables cultivated in our country, of which there are 40 or 50 kinds of major cultivation. There are many ways of classification, such as classification by botanical characteristics, classification of edible parts, agro-biological classification, temperature classification, classification of light, classification of nutrients, classification of edible methods and so on.
Vegetable plants are wide-ranging and diverse. China is also one of the world's origin centers of cultivated plants, in addition to a number of cultivated plants for vegetables, there are many wild or semi-wild species, such as caper, amaranth, quinoa, dandelion, fritillaries, etc., can also be eaten as vegetables.
