1.1 selection of place of origin
1.1.1 Non-polluted leafy vegetable production areas should be selected from sites that have good ecological conditions, no pollution sources that pose a threat to the environment of production sites within the planting area and upwind outlets and upstream of irrigation water sources. (The sources of pollution include industrial “three wastesâ€, medical sewage and waste, municipal waste, and domestic sewage).
1.1.2 Keep more than 100 meters away from the main road of the highway and try to avoid busy cities and industrial areas.
1.1.3 Regions with high background values ​​of soil heavy metals, high incidence areas of endemic diseases related to soil and water environment can not be used as bases for the production and processing of pollution-free leafy vegetables.
2 Cultivation measures
2.1 Variety selection The selection of disease-resistant, high-quality, high-yield, strong resistance, good varieties of goods. According to different planting seasons, choose suitable planting varieties. Planting winter and early vegetables, should choose cold-resistant, drought-tolerant early-maturing varieties; planting summer and autumn vegetables, should choose high temperature, resistant varieties.
2.2 Seed Disinfection and Treatment Seeds are disinfected and treated with sun seeds, soaking in warm soups, soaking with chemicals, or dressing with medicinal powders.
Warm soaking: Put the dried seeds in water of 50°C--55°C, soaking in the condition of constant stirring, and then naturally cooling, soaking for a certain time (10 minutes - 30 minutes) according to the water absorption requirements of the seeds, to absorb water and sterilize The role.
Seed soaking: Potassium permanganate, carbendazim and other agents soaked in disinfection.
Seed Dressing: Preventing downy mildew, black spot, 50% thiram, or 75% chlorothalonil, seed dressing at 0.4% of the seed amount, or 25% of toxic fungi, seed dressing at 0.3% of the seed amount; Soft rot can be used Cairongning or special seed coating agent.
When planting summer and autumn vegetables, some vegetable seeds (such as lettuce, garlic, celery, etc.) must be treated with low temperature to germinate normally, and should be refrigerated at low temperature (treatment) for germination.
2.3 Cultivate strong seedlings: Use low-toxicity and high-efficiency pesticides to treat bed soil or nursery nutrient soil, reasonably control the temperature and humidity of the seedbed, carry out hardening seedlings for 7 days before transplanting, and increase resistance to seedlings.
2.4 Site preparation remove solid waste such as crop residues, fallen leaves, waste plastic films, pesticides (bottles), etc., plunge the soil deep, dry and level the land.
2.5 Rational cultivation Avoid continuous cropping with other vegetables, cruciferous vegetables (such as cabbage, cabbage, etc.) Avoid continuous cropping. Advocate the rotation of dry and dry land, reasonably intercropping and interplanting to reduce and prevent the occurrence of soil-borne diseases and insect pests.
2.6 sowing timely planting. According to the characteristics of leaf vegetables, the current climate conditions and cultivation methods, select the appropriate sowing date. Planting vegetables for winter and early winter, usually sowing in winter, before and after the Spring Festival; planting summer and autumn vegetables, generally sowing in the summer and coming to the market in autumn.
2.7 Field management is reasonably dense and planted. Summer and autumn are recommended for cultivation of small leeches to avoid stagnant water in the fields, which will facilitate ventilation and light transmission, and reduce the humidity between plants. In the winter and spring season, the cultivation of bottom pods will be promoted, which is conducive to soil insulation and the maintenance of land cleanliness. Timely removal of pests and diseased plants reduces the number of pathogens and pests and controls the occurrence and spread of pests and diseases.
3 Principles and Methods of Pest Control
3.1 The basic situation of major pests and diseases
3.1.1 The main diseases are: downy mildew, soft rot, viral disease, black rot, black spot, dry heart, spot blight, gray mold and so on.
3.1.2 The main insect pests are: aphids, cabbage caterpillars, diamondback moths, leafminers, leeks, and beet armyworms.
3.2 Characteristics of major diseases and insect pests
3.2.1 The low-lying or rain-draining seedlings are prone to soft rot when they encounter rain;
3.2.2 The occurrence of downy mildew, black rot, and black spot disease in wet and cloudy weather;
3.2.3 The weather is prone to drought, cabbage caterpillar, diamondback moth, aphids and beet armyworm, but also conducive to the occurrence of viral diseases.
3.3 Principles of prevention and control The implementation of the plant protection policy of “prevention-oriented, comprehensive prevention and control†preferably adopts agricultural control, physical control, biological control, and scientific and reasonable chemical control, and controls the degree of harm and loss of pests and diseases and the maximum residue of harmful substances in the economic permit. Range and country allowable range.
3.4 Control methods:
3.4.1 Agricultural prevention and control measures should be adapted to local conditions, selecting good varieties with resistance (resistance) disease and strong stress resistance, cultivating disease-free pests and strong seedlings; properly planting densely; implementing crop rotation; paying attention to irrigation and drainage to prevent soil drought and water accumulation; Weeding reduces the number of pests.
3.4.2 Physical control
3.4.2.1 Cultivation in protective cultivation Yellow locusts are used to kill locusts and leaf miners, and they are hung at a density of 30 to 40 pieces per 667 to a height of 10 to 15 degrees above the top of the plants using a 30 to 20-inch yellow plate. .
3.4.2.2 Open-field cultivation Silver-gray membranes are suspended between fields to repel aphids and adult insects of moths or orthoptera are killed using insecticidal lamps.
3.4.3 Biological (biological agent) control
3.4.3.1 Control of cabbage caterpillar, diamondback moth, beet armyworm can be used BT preparations, sex attractants, azadirachtin, or nicotine.
3.4.3.2 Prevention and control of leeks pods can be used.
3.4.4 Chemical control Prompt chemical control in a timely manner. The selected agents should be mixed or used alternately to reduce the resistance of pests and insects. At the same time, attention should be paid to the safe interval between application and the use of highly toxic and high-residue pesticides is strictly prohibited.
3.4.4.1 Common Diseases Recommend the Use of Pesticide Species and Dose
