Fertilization techniques for out-of-season vegetables

Out-of-season vegetables refer to vegetables that are delayed or produced in advance on the basis of normal production time. At present, out-of-season vegetable planting technology is very common in our life, and it is also an important link to ensure the perennial supply of vegetables. So in the process of out-of-season vegetable cultivation, is its fertilization technology any different from the usual? How much do you know about its fertilization technology? Let's learn more about it.

1. Scientific selection of fertilizer species

The choice of fertilizer species is very important, but when we choose fertilizer species, it is ultimately decided by the varieties of vegetables. There are many kinds of vegetables, different vegetables are planted, then its demand for fertilizer is also different, just like vegetable leaf vegetables, we need to use fertilizers with more nitrogen content to promote the growth of vegetable leaves; for rhizome vegetables, we use fertilizers with high potassium content to promote the growth of roots and stems. And melons and fruits vegetables, their demand for nitrogen fertilizer, phosphate fertilizer, potash fertilizer is relatively large, and the fertilizer demand is also different in different periods, so we should allocate it scientifically. Finally, it is necessary to cooperate with the use of farm manure and organic fertilizer so as not to affect the quality of vegetables.

2. Proper use of fertilizer

The amount of fertilizer is also a key issue that we need to consider when applying fertilizer, and it can not be used casually. First of all, we need to analyze the fertility of the soil, and the second is to fertilize according to the growth habits and fertilizer characteristics of vegetables. The amount of fertilizer it needs is also different for different kinds of vegetables, so we need to make a comprehensive analysis before applying fertilizer. Generally speaking, the amount of fertilizer applied to root vegetables is mainly potassium fertilizer as the total fertilizer, and then 1/3 nitrogen fertilizer. While vegetables and leaves are mainly nitrogen fertilizer, auxiliary use of compound fertilizer can be. Melons and fruits of vegetables are micro-fertilizer for total fertilizer, 2/3 of phosphorus and potassium fertilizer.

3. Rational application of fertilizer

Out-of-season vegetable fertilizer should also be used reasonably, and nitrogen fertilizer should not be applied partially or casually. At the same time, we also need to fertilize according to their growth rules. Base fertilizer should be applied before planting, and topdressing should pay attention to cover the soil, do not hurt the leaves or roots of vegetables, melons and fruits, etc., and watering should be carried out in time after fertilization to avoid burning seedlings. Finally, we should pay attention to the time of fertilization, preferably on a cloudy day or after sunset.

4. Solve the threat of salt damage

There are conditions for different soil quality to adapt to fertilizer, so this is what we often call the problem of soil improvement. We can improve the soil quality by applying fertilizer, but if it is not applied properly, it will also pollute the soil. Salt damage is one of the most common problems in out-of-season vegetable cultivation in the process of fertilization. in order to avoid this problem, we need scientific watering and standard fertilization, which can reduce the salinity of the soil. so as to promote the growth of vegetables. There is more use of organic fertilizer, which is also a very effective way.

The above is the fertilization technology of out-of-season vegetable cultivation that the editor would like to share with you today, which can be collected by friends in need. In fact, no matter how to say that out-of-season vegetables are the same as other vegetables, the demand for fertilizer does not change much, so we still have to follow their fertilizer law and apply fertilizer reasonably. Only in this way can we ensure the healthy growth of vegetables.
