Key points of standardized cultivation techniques of garlic

1. Garlic field @ # @ 185mm. Choose the second field of garlic-rice rotation with loose soil, fertile soil, sufficient water source, convenient drainage and irrigation, suitable for growing garlic.

2. Meticulous ground preparation. After the previous crop harvest, take advantage of soil moisture ploughing, or when the field is semi-dry, use a rotary tiller to prepare the land, 2 meters open, the border width is 1.5-1.8 meters, three ditches are matched, the ditch depth is 0.2 meters, and the ditch width is 0.3 meters, fine soil preparation is achieved, and the soil is fine and can be irrigated.

3. Apply sufficient base fertilizer. Apply 50 piculs of farm manure, 75 kg of potassium sulfate compound fertilizer and 50 kg of ammonia bicarbonate per mu, spread evenly before soil preparation, and then plough.

4. sow seeds at the right time. The best local sowing time is from September 10 to 30.

5. Select garlic seeds and sow them at different levels. Garlic varieties are mainly moss-producing precocious Chengdu early-maturing Chengdu early-maturing and Jianglin early-maturing garlic, and properly planting Jiyang garlic and Cangshan garlic, which are both used for moss. The garlic cloves are graded according to the size of garlic cloves before sowing, and the large and middle cloves are reserved as seed cloves, and small cloves and clamp cloves are removed as garlic seedlings or commodities, so as to achieve hierarchical sowing and mixed planting is strictly prohibited.

6. Seed dressing with chemicals. Put the garlic seeds in the sun for 2 days before sowing, soak the garlic cloves in warm water for one day and night the day before sowing, change the water for 3 times halfway, after soaking and filter dry, mix the seeds with 50% methyl thiophanate and virus A, mix 0.5% of the seed amount, mix well and pile up for 6 hours before sowing. The seedlings emerged 7 days earlier after sowing than with dried garlic cloves.

7. Uniform sowing and shallow sowing. Planting requirements, plant row spacing of 4 × 6 inches or 5 × 5 inches, planting about 25000 plants per mu, sowing cover soil does not need to be too deep, slightly exposed garlic tip is appropriate, planting depth is strictly prohibited.

8. Weeding in time. Keep the garlic field moist after sowing, and spray herbicides within 1 week. Spray 50% Acetochlor EC 120-150ml or 48% Lasol EC 150-200ml with water 60 kg per mu. If there is still grass damage after the garlic seedlings come out, spray 100kg / mu with garlic caojing or 24% ethoxyfluorosidase EC 70ml mixed with water.

9. Fertilizer and water management. Emergence period, flourishing period, bolting stage, bulging period, drought resistance, waterlogging and drainage. Topdressing 3 times in time, topdressing at seedling stage combined with weeding in ploughing and loosening soil, applying dilute dung water 1000ml 1500 kg per mu, adding urea 7 kg, potassium sulfate 5 kg per mu, and applying 10 kg potassium sulfate compound fertilizer per mu during moss gestation, combined with drought resistance or furrow application.

10. Pest control. In winter and early spring, focus on the control of leaf blight, purple spot, virus disease (dwarf disease) and disease transmission sources-garlic maggots and aphids, focus on the control of fields in the old epidemic areas, and it is found that the diseased leaves and plants of leaf blight and purple spot disease are removed in time, clear ditches and discharge stains, and spray 50 grams or 64 percent of 100 grams of alum and 60 kilograms of water with 77% per mu. It was found that the field of garlic atrophy disease was sprayed with 100 grams of plant disease or virus A pesticide plus 1.8% trichlorfon crystal or 48% Lesbon EC 100 grams of 100 grams of water and 150 kilograms of water, and the control effect was better if it was re-sprayed once or twice at intervals of 6 mi 7 days.

11. Timely harvest. When the garlic moss is on sentry duty, one gram of 920 or two bolting agents per mu can be sprayed for 3 times, and the bolting period can be extracted 3 days ahead of schedule. When the garlic moss is bent and hooked, it is strictly forbidden to scratch the garlic leaves and affect the yield of the garlic mound. The mound is collected about 20 days after the moss is collected, and after the garlic mound is collected, the mound is removed in time to dry in the sun.
