Control pesticide residues
Select fertile soil with flat terrain and rich organic matter or sandy soil, and implement grain and vegetable rotation to avoid heavy cropping and continuous cropping, overcome continuous cropping obstacles, reduce bacterial sources and insect sources, increase growth potential, reduce the occurrence of pests and diseases, and control The number of medications.
It is strictly forbidden to use high-toxicity and high-residue pesticides that are prohibited by the state, and avoid using pesticides in the importing country. Promote the use of high-efficiency and low-residue pesticides, and promote comprehensive prevention and control of agricultural control, physical and mechanical control, and biological control. Try not to use less or less chemical pesticides, use broad-spectrum pesticides, and select a variety of drugs to reduce the number of medications. Such as: avermectin can control aphids, whiteflies, mites, lepidopteran pests, etc., zhongshengmycin can prevent and treat fungal diseases, bacterial diseases, both low-toxic or non-toxic, no residue, foreigners The content requirements are not very strict, or there is no testing requirement.
Control bacterial content
The international market requires strict requirements for the bacterial content of the product. In the production process, the organic fertilizer in the base fertilizer should be fully decomposed, especially human feces and urine, animal feces must be fermented at high temperature, fully decomposed, or subjected to high temperature disinfection, avoiding hospital waste, seriously polluting agricultural products, industrial products, and abandoned life. Products as organic fertilizer materials.
During the growing season, it is forbidden to use human excrement and livestock manure to make a field application for topdressing to prevent infectious diseases and eggs from contaminating products. It is best to use groundwater for irrigation water, use less ground water, and avoid contaminated water.
In the process of harvesting, grading, packaging, storage, processing and transportation, strict hygiene standards should be adopted in all aspects. The site should be clean, the water quality should be clean, the packaging materials should be environmentally friendly, the transportation tools should be hygienic, and the operators should have no infectious diseases.
Improve shape quality
The shape index is very important in the market competition, it is the focus of competition, and it is also the key to improving planting efficiency. It is the difficulty in raising the export rate and also the focus of production. Practical and comprehensive measures are needed to improve the quality and quality of the form.
It is necessary to select excellent varieties, especially to choose excellent varieties that are resistant to disease, beautiful, uniform, and straight, and consider the habits of the consumers in the importing country. For example, export to Japan, South Korea and other countries should use bright, red, or deep red, medium-column light yellow, small top, slightly thicker middle column, the main varieties are improved black rice five-inch carrots, Seoul six inches, etc.; Western European markets use light yellow and light red, and the middle column is thinner, like Ruimei.
The use of sapling cultivation increases the thickness of the soil tillage layer, improves the nutrient supply and the same conditions in the underground, reduces the deformed roots and improves the shape quality. In mid-June, Henan Province, on the basis of timely annihilation, applied the base fertilizer, intensive cultivation, and the spacing between the rafts was 20 cm to 30 cm. The width and height of the glutinous rice were soaked in the center when the gully was watered. Water is the principle.
The peak of the underground expansion generally begins in early October and ends in early November. In addition to satisfying the water supply, it is best to apply multiple irrigations, usually 2 to 3 times. The fertilization should contain humic acid or amino acids. Once in the first ten days of October, every 10 days thereafter. During the expansion period, it is necessary to timely supplement the foliar fertilizer rich in trace elements such as potassium, phosphorus, boron, calcium and molybdenum to prevent premature aging.
