#种菜不能缺少的肥料是什么? #
No matter where you grow vegetables, no matter what vegetables are planted, fertilizer is essential, no fertilizer vegetables can not grow well, but many people have a problem when fertilizing, that is, they ignore the nature of fertilizer and the nutrients it contains, some people like to use organic fertilizer, some people like to use chemical fertilizer, and vegetables need what fertilizer but do not know, sometimes the fertilizer used looks a lot, but vegetables just do not grow well, the problem is that the nutrients are unbalanced, some nutrients are excessive, some nutrients are lacking, this is the main reason why vegetables do not grow well.
Those who have engaged in planting should know that no matter what kind of crop, a total of 19 nutrients are needed in the growth process, in addition to carbon, hydrogen, and oxygen can be absorbed from the air, there are 16 elements that need to be absorbed from fertilizers and soil, and a large number of elements are: nitrogen, phosphorus, and potassium. Medium elements are: magnesium, calcium, sulfur, silicon. Trace elements are: boron, chlorine, molybdenum, iron, zinc, sodium, manganese, copper, nickel. If any of the above nutrients are missing, vegetables will also have problems, so the nutritional balance of growing vegetables is the key to ensuring good growth.
Like a lot of friends like to use chemical fertilizers when growing vegetables, always feel that the use of chemical fertilizers saves time and effort, fertilizer efficiency is fast, and it is troublesome to use organic fertilizer, one is the lack of organic fertilizer, the second is the amount of organic fertilizer is more, and the third is that organic fertilizer needs to be fermented, and the fermentation process will produce odor. But I don't know, there is no chemical fertilizer with complete nutrients, take the compound fertilizer with more nutrients as an example, it only contains three elements of nitrogen, phosphorus and potassium, and other elements are still lacking, although there are various nutrients in the soil, but can not meet the needs of plant growth.
Let's talk about some organic fertilizer, organic fertilizer is made of fermentation of various animal manure, plant residues, various grain scraps, etc., which not only contains nitrogen, phosphorus and potassium, but also contains a variety of trace elements, nutrients needed for plant growth, organic fertilizer is all there. Moreover, organic fertilizer is rich in organic matter and humus, and the fertilizer effect period is long, which can not only meet the needs of various nutrients for plant growth, but also loosen the soil, nourish the land and fertilize the land. Although the nitrogen, phosphorus and potassium content of organic fertilizer is not as high as that of chemical fertilizer, this determines the amount of use.
Therefore, according to the demand for fertilizer for vegetable growth, the most indispensable thing to plant vegetables is organic fertilizer, if there is no organic fertilizer, more than a dozen kinds of nutrients rely on the use of chemical fertilizers, and need to supplement a variety of them, which is not only time-consuming and laborious, a waste of money, and vegetables may not grow well. But using organic fertilizer is different, if organic fertilizer is sufficient, even without chemical fertilizer, vegetables can still grow well. If the organic fertilizer is insufficient, it can be combined with an appropriate amount of compound fertilizer to supplement the deficiency of nitrogen, phosphorus and potassium, and various medium and trace elements, organic fertilizer and medium and trace elements in the soil can meet the growth of vegetables.
Therefore, among all fertilizers, organic fertilizer can be regarded as a veritable universal fertilizer, which is also a recognized fact. There is also an important problem, if you don't use organic fertilizer, just use chemical fertilizer every year, the soil will become worse and worse, more and more hard, and the fertility will be less and less, the reason is that the soil lacks organic matter, even if you use more chemical fertilizer, because the soil has no organic matter, it will be hard, compact, not breathable, the root system is not well developed at all, the root system is not good, it can not absorb nutrients, how can the seedlings grow well?
To sum up, the most indispensable fertilizer for planting vegetables is organic fertilizer, the real universal fertilizer or organic fertilizer, therefore, the use of organic fertilizer must be paid attention to when planting vegetables, the principle is: organic fertilizer is the main, supplemented by chemical fertilizer.
