Live leeks are generally broadcasted, with few seedlings transplanted to harvest seedlings for consumption. Its pollution-free cultivation sowing management is as follows:
1. Seeding in early spring and February-March, using greenhouses and small sheds for cultivation; planting in spring (April-May), planting multiple seeds under melons, eggplants and beans, or mixing with other green leafy vegetables, sowing , successively harvested. Before the planting, the vegetable field is to be thoroughly turned and limed, spreading 150 kg every 666.7 square meters. At the time of site preparation, the decomposed human and animal manure was used as the base fertilizer. About 3,500 kilograms were planted for every 666.7 square meters of spring and 1,500 kilograms for summer broadcasters and 2,000 kilograms for autumn broadcasters. The surface is fine and smooth, and it should be deep trenches with a height of 1.2-1.5 meters. For every 666.7 square meters, the seeding rate is 0.5-0.75 kg, sowing date is earlier and the seeding rate is slightly larger.
2. Do not cover soil or cover thin soil after sowing, or cover with fine sand or grass ash or human and animal waste. It is also possible to use plain soil instead of earth covering. After sowing, as the weather and the soil were topped with water, the seedlings emerged in about 10 days. In spring, the temperature is low and the water content is high. Generally, watering should be controlled, and watering is often performed only at high temperature or in drought. The growth of Chinese leeks is not a good thing. As the saying goes: "A sunny day's leeks, a rainy leeks" means this. From the time of sowing to the length of 2 true leaves, select the first top dressing on sunny days; the second top dressing after about 12 days, the third top dressing after the first extraction, and the subsequent top dressing Once fertilizer once. Top dressing is mainly quick-acting nitrogen fertilizer, applying about 10 kg of urea per 666.7 square meters or 2-3% of human fecal urine. And remove weeds in the field in time.
3, in summer and autumn broadcast leeks just 3-5 days emergence, emergence should be promptly weeding, and strengthen water and fertilizer management to keep the soil moist. In the high-temperature summer season, it is necessary to cover the shading net to cool and moisten the water, so as to create a suitable temperature environment conducive to the growth of the leek, and to increase the output and improve the quality. When the plants are about 15 cm high, they are harvested in time (either at intervals or once at harvest). In the 15 days before harvest can be applied 2-3 into human fecal urine, in the later period, topdressing mainly with available nitrogen fertilizer, and timely watering. Otherwise, it will quickly bloom and affect the quality and yield.
Sweeteners are Food Additives that sweeten soft drinks. Sweeteners can be divided into nutritional sweeteners and non-nutritional sweeteners according to their nutritional value. According to its sweetness, it can be divided into low sweetness sweetness and high sweetness sweetness I flavor; According to its source can be divided into natural sweeteners and synthetic sweeteners. Natural sweeteners include stevia, grosvenin, licorice, disodium glycyrrhizinate, tripotassium glycyrrhizinate and trisodium.
