In late August, it is the main season for the onion and ginger. In previous years, most farmers often chose to apply fertilizer at one time. In fact, this method of topdressing is wrong. So how should the green onions and ginger be topdressed, how much should they be pursued, and what kind of fertilizer should they pursue? In response to these questions, experts have answered for you. Topdressing should be appropriate, the method should be scientific Vegetables like cool green onions and ginger are generally used in the late August. The main reason is that after entering September, the weather turned cold, and the green onions and ginger entered the rapid growth period, which is the key period for increasing production and high yield. Late August is the early stage of the key growth period, and it is very scientific and practical to carry out a large topdressing. However, in recent years, vegetable farmers have some prejudice in fertilization, which has affected the growth of green onions and ginger and polluted the soil. Vegetable farmers often think that the greater the amount of fertilizer, the better, in fact, this is unscientific. Some vegetable farmers use more than 100 kilograms of chemical fertilizer per mu, and organic fertilizer is also about 3 cubic meters per acre. Moreover, vegetable farmers generally apply nitrogen fertilizer, and it is considered that nitrogen fertilizer has a good yield increasing effect. Expert analysis believes that these fertilization methods or concepts are not correct. At the same time, some farmers are not right in the management methods of green onions and ginger. Fertilization should be adapted to local conditions and appropriate amount of topdressing. Many vegetable farmers believe that green onions should be ditched and topdressed. In fact, this is also incorrect. It is not easy to cut the green onions and chasing the roots. This is not conducive to the growth of green onions. Organic fertilizer should be completely decomposed Vegetable growers know that organic fertilizer is good for the growth of green onions and ginger, and it is often applied when applying organic fertilizer. 1 mu of land 2 cubic meters of farmhouse organic fertilizer is enough, more is a waste. In addition to paying attention to the right amount of organic fertilizer, it should be noted that it must be completely decomposed. If it is not completely decomposed, vegetables are prone to pests and diseases. Most vegetable farmers are hard to completely decompose organic fertilizers themselves, and recommend farmers to apply commercial organic fertilizers. At present, the state is vigorously promoting the practice of weight loss and drug reduction, and the increase in the production of vegetables is somewhat not proportional to the increase in the use of chemical fertilizers. In summer, there is a lot of rain, and more than 100 kilograms of chemical fertilizer is applied to 1 mu of land, which is washed away by the rain. The vegetable farmers spend money and the effect is not good. Experts suggest that the application amount of compound fertilizer of green onion and ginger should be about 20 kg per mu, which can supplement the nutrition of vegetables and reduce soil pollution. Multiple doses, balanced nutrition The correct method of fertilization is: in the principle of “eat less mealsâ€, take green onions as an example: from colonization to harvesting, it can be applied 3-4 times to prevent de-fertilization in the late growth stage of green onions. After planting, the onion seedlings grow slowly, and the fertilizer can be properly chased. In late August, the onion plants will enter the vigorous growth period and carry out a large topdressing; from late September to early October, the photosynthetic products of the onion will be accelerated to store and store, and the onion yield will increase significantly. During the period, another fattening was carried out. It is very important to master the methods of multiple application during the big topdressing period, and pay attention to the nutritional balance of fertilization. Fertilization of green onions and gingers should focus on the application of nitrogen, phosphorus and potassium on the basis of adding organic fertilizers and deep-turning soils, while paying attention to the application of elements such as boron, zinc and calcium. According to the demand characteristics of green onions and ginger for nutrients, a large amount of elemental fertilizer from regular manufacturers can be used.
