Whenever greenhouse vegetables are facing the flowering and fruiting period, the temperature of greenhouse vegetables should be properly adjusted, because the suitable growth temperature is different. For example, the temperature in the greenhouse should not be too high until the flowering period of vegetables in the greenhouse. Excessive temperature will lead to the rapid death of pollen, thus reducing the pollination probability of greenhouse vegetables and making solanaceous vegetables easy to drop flowers and fruits. When the greenhouse vegetables arrive at flowering stage, it is necessary to keep the temperature in the greenhouse in a moderate state, because moderate temperature can well stimulate flower bud differentiation, so that the nutrients absorbed by the greenhouse vegetables can be smoothly transferred to the flowers and fruits of the greenhouse vegetables.
2, greenhouse vegetable planting technology encyclopedia 1- light control
In fact, it is not difficult to find that when we enter autumn, the temperature is still high, but most greenhouse vegetables have gradually begun to change from yellow leaves to fallen leaves. Why? Because these greenhouse vegetables are sensitive to light, not all temperature control. After the middle and late September of each year, the sunshine time in the northern hemisphere of our earth will be shorter and shorter, but the vegetables in the greenhouse have sensed this change of light and started to store nutrients to cope with the cold winter and lay an excellent foundation for the growth of trees and buds in the coming year.
Greenhouse vegetable cultivation needs to do the following:
1, rational land planning
Before planting, friends should make a detailed plan of their land, what to plant and where to plant it.
You can consult more experienced old farmers or experts, and you can avoid many detours.
2. Deeply cultivate the land. When you mix sphagnum and farmyard manure into the soil to be planted, you can start plowing. If it is a field, you might as well use a rotary tiller. After all, mechanical operation saves labor and time, and it is deeper than manual tillage.
If it is a courtyard vegetable garden, you can only be prepared for physical exercise. Although you are very tired in this respect, you must not be lazy. Deep cultivation, loess becomes gold!
3. Three-dimensional space
If you grow vegetables that like climbing, you need to install vines for them to help them climb smoothly. Of course, this can not only save garden space, but also help the growth of crops such as beans and cucumbers.
Step 4 get plenty of water
Newly unearthed vegetable seedlings need a lot of water. Sufficient water enables them to thrive faster. If it is a vegetable in a flowerpot, it needs to be watered frequently, because these plants are easier to dry than those planted directly on the ground.
5. Clever fertilization
Although fertilization is very beneficial to the growth of vegetables, excessive fertilization will burn the roots of vegetables and make your efforts go up in smoke. Conditional friends can ask experts to test your soil, and they will find out what is missing in the soil, how to solve it and so on. This is more conducive to the growth of vegetables than uncontrolled fertilization.
