In february, garlic matured to meet specific conditions, with the main factors affecting the timing of planting, species selection, the climate environment, planting techniques and geographical latitudes。
1. Timing of planting:
Garlic maturity is directly related to planting time. In the northern region, garlic can be harvested in february of the following year if it is planted in a greenhouse or a large shed in september-october. Early spring harvests can also be achieved through the use of membrane-cover technology for garlic in the yangtze basin. Ground-planted garlic is usually sowed in march and can be grafted only in june。
2. Choice of varieties:
Pre-literate varieties, such as water and water, and pre-literate garlic in peng county have a birth period of approximately 180 days, with 20-30 days of graze before the late-literate varieties. Garlic can be harvested 90 days after its planting in yunnan. The selection of low-temperature-resisting varieties can facilitate early mossing through springing。
3. Climate regulation:
Facilities agriculture allows for counter-seasonal production by regulating the humidity. It is maintained at 20-25°c during the day and at 12-15°c during the night, and can accelerate the development of garlic by means of light supplementation measures. The use of the "triple membrane cover" technique in the mountains + small arch sheds + large sheds will allow garlic to be marketed as early as mid-february。
4. Plantation techniques:
Foot bottom fertilisation combined with the application of potassium phosphate to the leaves can facilitate chromatization. Controlling the number of waterings and maintaining the relative humidity of the soil over the long term in garlic. The hibernation period can be broken by the use of erythroacin solutions, but concentrations must be within 50-100 ppm。
5. Geographical differences:
In areas south of latitude 25° n, such as guangdong and guangxi, winter temperatures are suitable for natural growth. Sichuan wengjiang uses the "grynx" model, which began harvesting late in january. High-altitude areas are dependent on plant cultivation and plain areas can be pre-cooked through improved varieties。
In order to achieve the february harvest, the selection of pre-literate varieties was made in conjunction with facilities, with 3,000 kg of curing organic fertilizer per acre used as base fertilizer, and 3 times of urea + 0. 2% potassium sulfate solution applied during growth. Keep the average daily temperature above 15°c and light for not less than 10 hours. Water was stopped 10 days before the harvest, and when the garlic reached 15-20 cm, it was collected in the middle of the sunday afternoon with a special mossing tool. Attention is given to rotational retrenchment to prevent endemic diseases, which require soil disinfection by more than 50 per cent of the population. Garlic is rich in garlic and selenium, and it is recommended that eggs or skinny meat be cooked with nutrients。
