For our growers, the vegetable field is our lifeblood, without the vegetable field can not grow vegetables, we must all understand this truth, therefore, we usually pay attention to the maintenance of the vegetable field, this maintenance includes many aspects, such as ploughing, drying the land, fertilizer and so on.
For the ploughing of the vegetable field, in fact, many people have not done a good job, we think about it, the vegetable field is to feed our vegetables, and the growth of vegetables will consume the "vitality" of the vegetable soil, if the vitality of the "soil" is consumed too much, too much, but can not be supplemented, the vegetable field will become more and more barren.
Not only that, in the process of growing vegetables, there are often problems with pests and diseases, there will be some germs, eggs, pests left in the vegetable field, if we are just simple ploughing, although we can also eliminate some pests and bacteria, but can not be completely eliminated, therefore, when we plough the vegetable field, we also need to do the following two work.
1. Use quicklime and plant ash according to the situation
Quicklime is a highly alkaline substance, and when exposed to water, it will emit high temperature, is the nemesis of germs, insect eggs, and pests, if we sprinkle quicklime in the vegetable field, and then plough it, let the quicklime mix into the soil, quicklime will absorb the water in the soil, and then produce a reaction, emitting high temperature, so as to kill the pests, insect eggs, and bacteria hidden in the soil, and can also change their living environment, resulting in the death of these pests, insect eggs, and bacteria.
However, quicklime is not used casually, some healthy and normal vegetable plots are not recommended to use quicklime, only those vegetable plots with many pests and diseases, we use quicklime, or newly cultivated vegetable plots, we use quicklime to sterilize and disinfect, because the alkalinity of quicklime is too high, and if you sprinkle quicklime into a good vegetable plot, it will destroy the balance in the vegetable soil, but will affect the fertility of the soil.
Therefore, for a healthy vegetable field, we only need to sprinkle plant ash on the vegetable field, and the plant ash also has the effect of sterilization and disinfection, although it is not as strong as quicklime, but the effect is not bad, and the plant ash also has the effect of regulating soil acidity and alkalinity, not only will not reduce the efficacy of vegetable soil, but will also improve its efficacy.
2. Supplement beneficial bacteria and organic matter
The health of the soil is determined by the amount of beneficial bacteria it contains, and if the amount of beneficial bacteria is small and the number of harmful bacteria is large, then the soil is easy to cause the vegetables planted in it to be infected with diseases.
Therefore, we usually need to add more beneficial bacteria to the vegetable field, and we also need to supplement organic matter and humus, because the food of beneficial bacteria is organic matter and humus, and if there is no organic matter and humus, the beneficial bacteria will slowly "wither".
Therefore, when we plant vegetables, we should often apply base fertilizer to the vegetable field, and use more compost as base fertilizer, which can not only increase the beneficial bacteria in the soil, but also increase organic matter, humus, crude fiber, etc.
These two key points can be summed up as nothing more than sterilization and insecticide, and then replenish beneficial bacteria, organic matter, humus and crude fiber, so as to improve the health of the soil;
