Scientific sowing is the premise of the high yield of garlic. The key to successful sowing is to grasp the appropriate sowing time, fertilization for soil preparation, seed selection and seed selection, seed treatment and reasonable close planting techniques.
I. Appropriate sowing date
The timely sowing of garlic is the key to obtaining high yields of garlic sprouts and garlic. The selection of the sowing date follows two principles: First, the suitable temperature (16°C-20°C) required for the germination of the species flaps; second, there are 5-7 unfolding leaves before wintering, and the winter can be safely maintained. The vegetable farmers can sow according to the climatic conditions in various places.
Second, the soil fertigation
The land on which the garlic was cultivated was ploughed immediately after harvesting of the former crop, and soil preparation was performed before sowing. Basal fertilizer should be applied before ploughing. Due to the long growing period of garlic, high population density, large amount of fertilizer is needed, generally, high-quality organic fertilizer such as manure, manure, and other 5000-8000 kilograms of Mushi, and with 20-30 kg of phosphorus and potassium fertilizer. Organic fertilizers must be fully cooked. If raw manure is used, it will burn the garlic roots during fermentation, and it will also cause underground pests, especially in the mantle. It is necessary to fine-tune the earth and make it 1.5-2 meters wide. It is better to extend things.
Third, retain seed selection
Selection of garlic should begin with field management. First, select plants with normal yellow leaves and no pests. From the middle of the election, the head was large and round, and the bottom was flat without damage, uniform in size, with skin color and flesh color, and the number of splitting was in line with the characteristics of the variety. The head was single, single, single and single. Before sowing, garlic seeds should be carefully selected, and garlic heads with large heads, few petals, and neat petals should be used; those with disability, rotten flaps, air-dried, soft, no buds, worms, and roots should be eliminated.
Fourth, seed processing
1. Handwork. The selected garlic must be squashed, with stems, stems (trays) and broken flaps removed. Stem must be removed, otherwise it will affect the water absorption, hair root and seedling growth of the species flap.
2. Drug treatment. Commonly used drugs include white rot, thiophanate methyl, and fennel. According to the test, the best use of white rot treated garlic is to use 100 grams of white rot and 3-4 kilograms of water to spray on the white rot. The spray is mixed and the garlic is evenly sprayed. Let it sow. After this treatment, the garlic cloth has absorbed water, and the rough surface is also conducive to sowing.
Fifth, reasonable close planting
Close planting is the basis for increasing production. The yield of garlic sprouts and garlic bulbs is composed of the number of plants per acre, the number of garlic plants per plant, the weight of pods, and the weight of pods. According to the characteristics of the varieties, proper close planting should be done so that there are more plants per acre. Early-maturing varieties generally have shorter plants, fewer leaves, shorter growth periods, and correspondingly higher densities. It is better to plant about 50,000 mu per plant, with a row spacing of 14-17 cm, a plant spacing of 7-8 cm, and a variety of 150 mu. -200 kg. The mid-late-maturing varieties have long growth periods, tall plants, a large number of leaves, and correspondingly small densities, so that the structure of the population can be rational to make full use of light energy. Density should be mastered in acres of planting 40,000 up and down, spacing 16-18 cm, spacing of about 10 cm, about 150 kg per mu.
