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 highly toxic and high-residue pesticides that are prohibited by the state, and the importing country should not be used to test the types of pesticides. 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 or use less chemical pesticides, use broad-spectrum pesticides, and use a variety of drugs to reduce the number of medications. For example, avermectin can control aphids, whiteflies, mites, lepidopteran pests, etc., zhongshengmycin can prevent and treat fungal diseases and bacterial diseases, both of which are 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 has strict requirements on the bacterial content of the products. 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, human excrement and livestock manure should be used as a top dressing to prevent contamination of the source of infection and eggs. 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

Shape indicators are very important in the market competition, the focus of competition, and the key to improving planting efficiency. It is the difficulty in increasing the export rate and 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, beauty, uniformity, and straightness, 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 soil tillage layer, improves nutrient supply and synchronic conditions in the underground, reduces deformed roots and improves the appearance quality. In the middle of June, Henan Province, on the basis of timely smashing of the front scorpion, applied enough 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.
