Key points of planting management:
A stubble plowing, stubble; after crop harvest, was 30 cm, exposure to 20 days or so, effectively kill the bacteria in the soil of Cordyceps and reduce replant disease. Not excessive use of fertilizer, easy to cause soil compaction, salinization of land, so that high input and output disproportionate. Should take the land way. Attention should be paid to the combination of agriculture and agronomy.
Two. Soil preparation and fertilization. Garlic planting need organic fertilizer, fertilizer supplement, removal of nitrogen and phosphorus potassium, sulfur can improve the quality of garlic, recommend the use of manure fertilizer containing bacteria. Preparation, 1 acres of 45% organic fertilizer and 200 kg + Le bacteria supplement Guoguang high concentration compound fertilizer 150 kg + 5 kg per mu Guoguang strogner; with Paul (kill insects underground particles) 3-5 kg. Fertilizer applicator evenly, land formation and particle structure.
Three, the selection of seed dressing; healthy garlic, garlic will be available in Acton (Syngenta seed treatment agent) soaking (prevention of stalk rot and insect type); or 50% dragon dragon duoning + carbendazim seed dressing to prevent fungal diseases. Or strong biological fertilizer of Seed Soaking with 500g. Soaking seeds to prevent garlic soil borne diseases and pesticide residues is beneficial to seedling growth.
Four, timely sowing; on October 5-15 5cm, the temperature at 18 degrees Celsius, the spacing of 20 cm /3 tree, 15cm standard planting spacing.
Five, seedling management, about 7 days at normal temperature.
Weeding: herbicides are closed prior to germination.
Commonly used herbicides: Shi Tian 150ml+36%, 90ml, 45 kg (3 barrels) of water spray.
Spraying attention when walking backwards, preventing stampede membrane effect.
Pest control:
After emergence, 45% with high chlorine 100ml+ 100ml+ 100ml against the true spirit of dichlorvos 45 kilograms of water spray page, once 7 days later, 3 times. Pest control.
Six 、 water and fertilizer management. With small water pouring, pouring water first after sowing, seedling close to second water pouring, pouring water at Seedling Stage 1, before the winter 1 pouring water, green stage water pouring 1 garlic, the differentiation stage of water pouring 1, to mention 3 ~ 4 sprouts before pouring water, put 5 to 7 days before the stop bolt when they were in water. After 3 ~ 4 were provided pouring water. Cover film than that of garlic sprouts put garlic as early as 5 ~ 7 days.
Garlic top does not make a film, to buckle artificial seedlings, garlic bud dew, but exposing to film, and weeding.
Seven, insect pest control: the main control of aphids, thrips, Diqu. Focus on thrips, because the thistle spurs mouthparts can pierce into leaves and garlic, causing grayish white spots appear garlic leaves, garlic, spotted the wound, disease susceptibility and resistance to storage, generally unwilling to buy or purchase price low. Should focus on thrips and other pests. After the emergence of many mites, thrips by Ding + the see's spray. Diqu occurs because the planting and the use of organic fertilizer raw garlic, or a bad mother trick worm eggs, chlorpyrifos, abamectin by root irrigation.
Eight, to prevent and cure diseases mainly controlling leaf blight, Botrytis cinerea, Alternaria porri. Prevention mainly focuses on prevention, prevention of seed soaking and spraying treatment. Few drugs used in the past few years, the disease showed an increasing trend. Last year, the market is difficult to store garlic after lesion, it is difficult to sell a good price.
The bolting stage management, the relationship between quality and yield of garlic garlic, garlic planting management in the most critical period, is also the most extensive management of garlic in a fine. The management of good, good quality and high yield of garlic garlic, a year will have a good return on investment, if the management or improper management, garlic, garlic products appear, is basically a year for nothing. link with section tenth [bolting stage management].
Nine, growth management: garlic into the rapid growth period, the need for water, fertilizer, disease and insect pests have also occurred a lot, should strengthen the management of the latter.
For normal non disease plots, should be pouring water, pouring sufficient water through, Mu Shi Chong fertilizer or soluble compound fertilizer or soluble alginic acid, such as humus acid, amino acids and other fertilizer 10~15 kg. No watering and fertilizing many plots replant disease plots, small water should be poured, Mushi soluble alginate (humic acid, amino acid fertilizer) from 5 to 10 kg, and foliar fertilizer, foliar fertilizer or 0.5% urea + 0.3% potassium dihydrogen phosphate diluent, alginic acid, brassinolide, 5 ~ 7 days of a jet.
For the heavier replant disease and yellow leaf plots, soil moisture should be timely watering, first foliar fertilizer, foliar fertilizer dilution of potassium dihydrogen phosphate or 0.5% urea + 0.3%, 5 ~ 7 days of gush, timely watering.
Ten, the bolting stage management. (this is the most important management period, to the situation last year, good management, a good friend of garlic, can sell 1.67. And bad management, may be infected with diseases or thrips such as smoke caused by yellow spots, seriously affecting the quality, generally sold only 0.6 yuan The 7- 10 days after the beginning of watering, watering once, 3 times the general pouring water mast frequently, promote the rapid growth of stem phosphorus, to obtain high quality garlic. Try to minimize the yellowing of leaves. Can be sprayed protective fungicide to prevent disease, use of M-45, Dakonin, a supporter, good people, high any fungicide and disease prevention; with Atonik application, dilute America enhanced disease resistance, leaf nutrients can be sprayed Wo portrait, Ye Nengzhuang two, hydrogen potassium alginate etc., if ever, pest thrips so, by Ding, the see's mites pest control spray, spray Caution! Interval, liuzu period. about 5-10 days before bolting withdrawal.
Eleven, garlic expansion period, timely watering, add fertilizer.
After the garlic bolt into the bulbification stage, to timely watering and fertilizing, to prolong the time of photosynthesis. After bolting, foliar spraying.
