Avoid using several kinds of fertilizers for planting potatoes and sweet potatoes to avoid losses every year
Organic fertilizer - a base fertilizer for cultivating potatoes and sweet potatoes.
Potatoes and sweet potatoes are root crops with high requirements for soil nutrition. When it comes to growing potatoes and sweet potatoes, chemical fertilizers are the main thing. However, organic fertilizer is not in the general sense, and it is still necessary to pay attention to it. First of all, the most important thing to focus on in potatoes and sweet potatoes is how to compost. Such as human manure, chicken manure, cow manure, should be thoroughly fermented to ensure that they do not breed pests. Improper application of chemical fertilizers will not only cause adverse effects on crops such as potatoes and sweet potatoes, but also cause pests and seriously reduce grain yield and quality. Therefore, potatoes and sweet potatoes should be used with well-rotted organic fertilizer in order to achieve the purpose of high yield, high quality and high yield.
Chlorine fertilizers, it is better not to use.
Chlorine fertilizer is a type of chemical fertilizer that contains chlorine, such as potassium chloride, calcium chloride, etc. However, potatoes and sweet potatoes are sensitive to chloride during growth and development, so chloride fertilizer is one of the two crops to avoid as much as possible. The rationale for this is that the root growth of potatoes and sweet potatoes is inhibited after the application of chlorine-containing agents, which leads to a decrease in their yields. In addition, the application of chlorine fertilizer will also have an adverse effect on the dry matter accumulation of potatoes, sweet potatoes and other crops, which in turn will have a certain impact on their taste and quality. Although potatoes and sweet potatoes have a high demand for potassium, care should be taken to avoid chlorine-containing fertilizers such as potassium chloride in favor of other potassium during application.
n- To be cooperative, not over-applied.
As one of the most important nutrients, nitrogen plays an irreplaceable role in the growth of crops such as potatoes and sweet potatoes. However, when cultivating these two crops, care should be taken to apply nitrogen and not to overdo it. Nitrogen application alone, or excessive nitrogen application, will cause the seedlings to grow tall and stout, green and large leaves, but can not fully develop in the soil, resulting in good leaves, but no fruit. Therefore, whether it is base fertilizer or top dressing, we should not only apply nitrogen or excessive nitrogen, but pay attention to the reasonable combination of nutrients such as nitrogen, phosphorus and potassium, so as to avoid the seedlings growing too vigorously and causing yield reduction.
Potatoes and sweet potatoes require different fertilizers depending on the crop, so be careful when choosing them. Under normal circumstances, organic fertilizer is the mainstay, and an appropriate amount of phosphorus and potassium is added at the same time, such as plant ash, potassium sulfate, superphosphate, etc., which can replace the simple application of chemical fertilizer. In the potato swelling stage, you can choose a compound fertilizer with high potassium and an appropriate amount of nitrogen mixed with it. This combination not only accelerates the growth of the leaves, but also prevents the leaves from turning yellow and falling off prematurely, and also ensures the development of underground stems and increases the yield of the crop. Of course, what kind of fertilizer to apply and how much to apply depends on the actual condition of the crop.
The conclusion is that in the production of potatoes and sweet potatoes, in order to improve the quality and yield of potatoes, scientific fertilization must be carried out. First of all, it is necessary to ensure the sufficient fermentation of organic fertilizer to prevent the breeding of pests;Secondly, in the process of fertilization, it is necessary to avoid chemical fertilizers containing chloride ions, otherwise it will cause adverse consequences to the growth and quality of rice. In addition, it is necessary to pay attention to reasonable cooperation when applying nitrogen, and avoid too much application, otherwise it will lead to too many plants and underdeveloped roots. When planting potatoes and sweet potatoes, it is necessary to fully understand their growth characteristics and requirements, and take appropriate chemical fertilizer coordination and fertilization measures in combination with local specific conditions to ensure the healthy growth and high yield of crops. In order to grow potatoes and sweet potatoes with high yield and good quality, we must first have an accurate understanding of the need for chemical fertilizers. We must continue to strengthen our understanding of agriculture, strengthen our understanding of agriculture, strengthen guidance for agricultural production, and promote the development of agriculture.
