First, scientific fertilization. The first fertilization will be carried out after the return of spring in spring to make up for the growth of the onion root system and to lay the foundation for the lush growth of the aboveground part. Fertilization should be based mainly on fully decomposed organic fertilizers, with 1,000 kg applied per acre, adding 20 kg of superphosphate and 10 kg of potassium sulfate. When the onion grows to 8 to 10 true leaves and the beginning of the bulb expands, the beginning of the application of the head fertilizer is applied even 2 to 3 times, and 10 to 20 kilograms of sulfuric acid can be applied per square meter to fertilize the middle of the bulb expansion. The emphasis is on the amount of fertilizer to be applied. When the beginning of the bulb expands, do not apply excessive nitrogen fertilizer to avoid "greediness." During bulb expansion, potassium sulphate should be added during fertilization at an amount of 5-10 kilograms per acre, as the lack of potassium on the onion will result in poor storage stability.
Second, timely watering. Pre-winter planting onions, spring water poured back to Qingshui, poured back to Qingshui to be timely, premature watering will reduce the temperature of the soil, is not conducive to the growth of onions, will inhibit the growth of plants too late, the occurrence of leaf dry tip scene. When onion bulbs begin to swell, it is necessary to control the length of water seedlings and seedlings and to control their length according to soil, climate, and plant growth conditions. When sandy soil or climate is dry, it is appropriate to shorten the seedling stage; clay soil, low-lying land, It is appropriate to prolong the seedling period. The goal is to increase the expansion of onion growth into bulbs, which usually takes about 10 days. It is generally believed that the mature tubular leaves of onions turn dark green, the leaves are hypertrophied, the waxiness of the leaves is increased, and the color of the heart is deepened, which is a sign of stagnant seedlings in this period. After the seedlings are sprayed, water is usually poured every 5 days to increase the bulb's rapid expansion. When there is partial lodging in the field, stagnant watering can be avoided to avoid storage after the bulbs are harvested.
