Organic vegetables can be described as more popular vegetables with very high prices and particularly desirable market returns. Thus, the development of organic vegetable cultivation has very broad market prospects. So, how do you grow organic vegetables? What do you know about organic vegetable technology and planting? Let's learn from little chief
Organic vegetable technology
1. Choice of varieties
Seeds and seedlings of organic vegetables must meet three basic requirements: first, they do not have genetically engineered genetically modified components, second, they do not use banned substances for treatment, and third, they are more insect-resistant. In organic vegetable production, certified organic vegetable seeds and seedlings should be selected, but conventional seeds that have been treated with unprohibited substances may be used during the initial stages of cultivation without the purchase of certified organic vegetable seeds and seedlings. It is also important to select the types of vegetables and good varieties that are resistant to insects and are suitable for local soil and seasons, such as spinach, carrots, carrots, soybeans, taro, taste, celery, ginger, ale, garlic, onions and onions。
2. Production base requirements
Organic production bases should be complete plots of land, which cannot be packed with conventionally produced plots, but organic conversion plots are permitted, and organic vegetable production bases must be clearly marked along the border with conventional plots, such as rivers, hills, artificially constructed quarantine strips, etc. The conversion from conventional production to organic production usually takes two years, after which the vegetables sowed are harvested as organic products; the start of the conversion period is calculated from the date of the application for accreditation to the certification body, during which the producer must operate in full compliance with the requirements of organic production。
3. Cultivation management
The cultivation of organic vegetables, mainly in combination with planting techniques, is carried out through crop rotation and the cleaning of fields, through the cultivation of seedlings, the replanting of roots and the start-up of plants。
The following should be noted:
1. The choice of suitable sites for the cultivation of organic vegetables should be based on the choice of places far away from cities and industrial or industrial sites, air-free, water and soil pollution, soil fertility, stasis, ease of drainage, accessibility and availability of organic fertilizers。
2. The choice of suitable crops and varieties for the cultivation of organic vegetables should be based on the selection of relatively small and long-lived crops such as spinach, carrots, carrots, garlic, beans, oxen, potatoes, etc. At the same time, high-quality, disease-resistant and strong-growing varieties must be chosen。
3. Scientifically arranged planting outlets should be long-term in accordance with crop characteristics and patterns of pests and diseases, with the main crop species scheduled for less hazardous seasons to avoid pests。
Rational application of organic fertilizers for a variety of non-polluted organic fertilizers such as human and animal faeces, plant staves, soybeans green fertilizers, grass-wood ash, soybean cakes, soybean waffles, etc. Fermented, fertilized, fertilized or followed。
5. Strengthen pest and disease control to improve field management, promote the growth of vegetables, increase resistance to disease, introduce drip irrigation to reduce air moisture, develop high levels of planting, strengthen grass-cutting in china, drain and cool wells in time after summer rains, reduce planting density appropriately, enhance ventilation and lightness, and take care of rotation. Vegetable pests are treated with aerobic bees, orange-coloured baiting of powdered lice, black-lighted baiting of night moths and moths, gold turtles, silver grey membranes to avoid aphids and insecticide-treated nets. In addition, the use of sugar vinegar to trap tigers could reduce the rate to 1. 3 per cent。
