At present, garlic is in the seedling stage and is about to enter the period of vegetative growth and reproductive growth. In order to improve the quality and yield of garlic and garlic, field management should be strengthened, timely irrigation and irrigation, moisture and nutrition should be ensured, and garlic growth needs should be met.
Ensure moisture and nutrition: garlic leaves are drought-tolerant ecological type, but under the conditions of adequate water and nutrients, can grow well, good quality and high yield, where irrigation conditions must be timely watering.
Application of Miao Miao Fei: After planting a month or so, water once every 10 days to keep the field moist, not too dry or too wet. Garlic stems and leaves suitable temperature for the growth of 12 ~ 16 °C, in late May flower buds and scale buds rapidly differentiate, garlic, garlic at the same time growth, the need for more water must be timely irrigation to meet the needs of growth. Combined irrigation with 25 kg of NPK fertilizer per acre.
Reapplying moss fertilizer: In the period of bulb elongation and bulb expansion, soil should be kept moist to prevent the soil from drying out. The suitable temperature for the elongation period of the garlic is 15 to 20°C. In June, the garlic sprouts vigorously and lasts for about 30 days. Fertilizer plants have a large amount of fertilizers, with 20-25 kilograms of urea per acre, and 15-20 kilograms of 40% nitrogen-sulphur fertilizer, which encourages the growth of bolts and garlic cloves. Harvest as little water as possible before 3 to 4 days.
The application of swelling fertilizer: after the harvest of garlic bulbs, enter the bulb expansion period, the plant growth is slow, the main growth and weight gain of garlic, bulb expansion temperature of 20 ~ 25 °C. This period should be properly controlled watering, keep the soil moist and promote bulb expansion. Stopping watering 5 to 7 days before harvesting, reducing soil moisture and improving storage stability. Garlic contains allicin, the application of sulfur fertilizer can increase the production of garlic and garlic, and increase the flavor, improve the commercial quality of garlic, generally with urea with copper sulfate or potassium sulfate as sulfur fertilizer, as the base fertilizer in the preparation for the site. During the expansion of garlic, foliar spray can be applied 1~2 times 0.3% potassium dihydrogen phosphate solution and trace elements fertilizer containing sulfur, promote the transfer of nutrients to the bulb (garlic), prevent premature aging of the seedlings. This period generally does not perform root urea topdressing, if topdressing urea will cause garlic spalling.
Prevention of pests and diseases of garlic: Garlic diseases include leaf blight, purple spot disease, virus disease, and soft rot, and insect pests are garlic sprouts. If pests and diseases occur, they should be promptly prevented and prevented from spreading. Bacterial blight and purple spot were treated with Shigao, carbendazim, chlorpromazine, antivirinone, mancozeb, or sulfanilone; bacterial soft rot was treated with streptomycin and bacillus glucoracil; viral disease was used. Virus A or bacillus g drug spray. Add foliar fertilizer when spraying, enhance plant resistance to disease. During the larval stage of Garlic Scorpion, roots were irrigated with trichlorfon or phoxim to eliminate the initial larvae. Adults were sprayed with deltamethrin on their leaves when spawning.
