How to fertilize vegetables in spring?

There are rhizobia in the roots of leguminous vegetables, and it is known that rhizobia can fix nitrogen, so leguminous vegetables need less nitrogen fertilizer than other vegetables in the growth process. The role of rhizobia in the early growth stage of leguminous vegetables is not obvious. Because the rhizobia are not mature at this time, the effect is not great. Therefore, it is necessary to apply sufficient fertilizer to the land, which is more conducive to the early growth of soybeans and vegetables. According to the soil conditions, organic fertilizer can be used on the land, and the organic fertilizer must be fully mature. Otherwise, root aging is easy to occur. In addition, in the growth process of leguminous vegetables, the demand for nitrogen fertilizer is small, but the demand for potassium fertilizer is large. Appropriate phosphate fertilizer should promote leguminous vegetables to blossom and bear beans. So in the process of fertilization, please pay attention to adding vegetation and calcium phosphate. Usually there is about 100 kg of vegetation and 20 kg of calcium phosphate per acre. When bean vegetables grow fast, pay attention to topdressing in time, usually once every ten days. Ether and potassium oxide are commonly used to promote flowering and pod setting.

Leaf vegetables should be the vegetables we usually eat the most, such as Chinese cabbage, leeks and spinach. During the growth of leafy vegetables, there is a great demand for tour fees. The root system of leafy vegetables is shallow, and the nutrients needed for normal growth can only be obtained in shallow soil, so growers should topdressing in time to ensure the growth of vegetables. Before planting, we should also increase soil fertility and fertilize the soles of our feet. Organic fertilizer is generally used as the base fertilizer, and the amount of organic fertilizer depends on soil fertility. Generally, about 2 tons of organic fertilizer is required per mu, and the forage 100 kg is required. During the growth of leafy vegetables, the demand for nitrogen fertilizer and potassium fertilizer is relatively large. Generally, urea is added once per plant, and the general dosage is about per mu 10 kg.

Fruits and vegetables need a little more fertilizer during their growth. Fruits and vegetables are our common tomatoes, eggplant, peppers, wax gourd and so on. Nitrogen, phosphorus, potassium, calcium, magnesium and other fertilizers that need to be cleaned during growth. Base fertilizer is similar to the above fertilization method. Because the flower bud differentiation of fruits and vegetables is fast, nitrogen fertilizer and phosphorus fertilizer should be supplemented in time to prevent the flower bud differentiation from being delayed. Generally, fruit vegetables should be topdressing three times, once fattening, once fattening and once fruit fertilizing. Usually, foliar fertilizer should be supplemented in time according to the growth of vegetables.

Root vegetables have a great demand for potassium fertilizer in the growth process of root vegetables, such as potatoes, radishes, beets and so on. Fertilization is mainly a combination of base fertilizer and topdressing, and topdressing is earlier. It should be noted that if nitrogen fertilizer is applied in the process of fertilization, it will make the leaves grow too vigorously and affect the growth of roots. Autumn rain should be carried out after the root vegetables are officially eaten, and about 5 kilograms of sugar-free urea should be added to promote the growth of column leaves. At the initial stage of rhizome formation, phosphorus and potassium fertilizer were added at a dosage of about 7 kg per mu to promote the growth of rootstocks, prevent excessive growth of leaves and affect the nutrient absorption of rootstocks. Sprinkle 1% ether on the leaves of root tuber, and sprinkle it twice.
