Environmental Conditions for Garlic Cultivation

1. Temperature: Garlic prefers cold environmental conditions. Its suitable temperature is -5℃~26℃. After garlic goes dormant, it can germinate and germinate at 3-5°C. The optimum temperature for stem and leaf growth is 12-16°C. The optimum temperature for the development of flower stems and bulbs is 15-20°C. When the temperature exceeds 26°C, the plants will become physiologically disordered, the stems and leaves will gradually dry up, and the underground bulbs will stop growing. In areas where the average temperature in winter is below -5°C, autumn sowing garlic Cannot overwinter naturally. Garlic plants complete vernalization after 30 to 40 days at a low temperature range of 0 to 5 °C.

2. Sunshine: Garlic that has completed vernalization begins to differentiate between flower buds and scale buds under long sunlight and higher temperature conditions. In the short-day and cool environment, it is only suitable for the growth of stems and leaves. Scale bud formation will be inhibited. Therefore, whether it is spring or autumn sowing, it must go through the conditions of low temperature and long sunshine.

3. Moisture: Garlic is a shallow root crop, which likes damp and is afraid of drought. The soil temperature is required to be high before and after sowing, so that the seedlings can germinate and root quickly. In the early stage of seedlings, reduce irrigation, strengthen cultivating and loosening the soil, promote root development, and prevent seed petals from becoming wet and rotten. The stem elongation period and bulb expansion period are the vigorous stages of garlic growth and development, and are also the most water-requiring stages. The soil is required to be kept moist, and the soil humidity is required to be reduced when approaching the maturity stage to avoid rotten necks caused by high humidity, high temperature, and lack of oxygen. Loose cloves, blackened garlic skin, and reduced quality.

4. Soil and nutrition: Garlic does not have strict requirements on soil types, but fertile loam is the best, loose and breathable, with good water retention and drainage performance, and the ecological environment is conducive to the growth and development of bulbs. The garlic is large and neat, with good quality and high yield. The optimum soil pH is pH 5 to 6.0. Too acid root ends become thicker, and the extended growth is stopped. Too alkalinity makes the seed petals rotten, and the small heads and single cloves of garlic increase, reducing the yield.
