1. Land preparation and bottom fertilizer

1, the type of base fertilizer must be full

The type of base fertilizer should meet the manure (pig manure, cow manure, sheep manure, chicken manure, etc.), compound fertilizer, microbial fertilizer, medium and trace element fertilizer (calcium, boron, zinc are particularly important), each of which has its own role. So be sure to apply it.

2, manure must be decomposed, and the more the better

Although it has been stressed that no matter what kind of dung, it must be fermented, and must be turned underground. However, there are always people who have luck in the actual production, use unfertilized manure, and finally lead to a series of problems such as root burning. Good food must first learn how to ferment the feces. For the fermented manure, the more the application, the better. There have been farmers who have tried 1 acre and a half of the pepper field. The 40-car (agricultural four-wheeler) fertilized manure has not been fattened, and the pepper grows. It is also particularly good. In actual production, we are unlikely to apply so much, but how to apply more than 5000kg to an acre.

Fermented manure, no foul smell.

The use of unfertilized chicken manure causes the tomatoes to burn.

3, do not use excessive compound fertilizer, etc.

Feces can be used more, but the amount of compound fertilizer is good. Sometimes, the more the use, the higher the yield. The general use of balanced compound fertilizer (such as 17-17-17) for bottom fertilizer is about 70 kg. Sufficient to use, too much use will often lead to salinization of the soil, the loss of trace elements in the crop, etc., and the boron fertilizer applied at the bottom is also enough to apply a little. For example, sodium borate pentahydrate is used. Gram is enough, if it is more, it will cause boron poisoning.

4, pay attention to soil disinfection

If the plots are planted in successive years, there are often a large number of soil-borne diseases. When the soil is prepared, it can be used to apply carbendazim, pentachloronitrobenzene, thiram and other agents, and then turn to the soil to effectively reduce the number of soil bacteria.

5, promote high ridge cultivation

After high ridge cultivation, the root growth space is larger, and the soil around the root system is more breathable, so that the root system can absorb water and nutrients more strongly, and the yield will be higher. At the same time, the high ridge cultivation can effectively reduce the soil. The transmission of the disease.

Second, the management of seedbed

6, the seedbed can not be short of water, but can not water too much

For your own seedlings, you must ensure the moisture of the seedbed. If there is water shortage, it will show that the drought is not long, and it will affect the flower bud differentiation. In the future, it will seriously affect the yield. If too much water is used, it will cause roots. .

7, pay attention to prevention and treatment of rickets and blight

These two diseases are often caused under the conditions of high humidity in the field. They have good preventive and therapeutic effects on the downy mildew and the chlorfenapyr. Good preventive and therapeutic effects.

8, pay attention to the prevention and control of whitefly and viral diseases

At present, it belongs to the early summer and early autumn season. The whitefly outside the greenhouse often flies to the greenhouse to spread the virus and spread the virus disease. Therefore, it is necessary to pay attention to the prevention and control of whitefly and virus disease in the seedling stage of vegetables (especially the solanaceous fruit). The thiamethoxam / pymetrozine + amino oligosaccharide / morpholinium hydrochloride / nymidine and other agents are sprayed or watered before transplanting, some of the agents are absorbed by the leaves, and some of the agents are absorbed by the roots, thereby better protecting the crops. .

Spraying or watering thiamethoxam + amino oligosaccharide before transplanting can prevent whitefly and virus disease.

Without precautionary treatment, the pepper infected with the virus caused by dwarf mosaic symptoms after being bitten by white powder.

Third, after transplanting treatment

9, the transplanting depth should not exceed the marrying interface

In order to prevent soil-borne diseases such as blight and verticillium wilt, cucumbers, eggplants, peppers and other vegetables are often grafted with seedlings. However, if the seedlings are deeper than the grafting interface, the germs can invade from the grafting interface and cause grafting loss.

Cucumber graft interface, if planted too deep, blight can continue to infect.

10. When planting water, it is a key period to prevent soil-borne diseases.

After transplanting, we often have to plant a fixed water. This is a critical period for the prevention and control of soil-borne diseases. For peppers, we can use the planting water to use water, and we can control it with 15 days or so. For the occurrence of blight, for the tomato, the agent such as zhongshengmycin/chunremycin can be used, which can effectively reduce the occurrence of diseases such as bacterial wilt, bacterial ulcer disease and bacterial necrosis. In addition, with the watering of the planting water, the use of a little microbial agent also has a good effect on soil-borne diseases.

11, pay attention to the choice of film

It is recommended to use transparent white mulch for winter anti-season vegetable cultivation, so that sunlight can pass through the mulch to make the soil absorb more heat and increase the ground temperature, especially in the deep winter season, although the use of black mulch is better. Weeding, but the soil can not absorb more heat so that lower ground temperature will affect crop growth.

Complete Greenhouse

A greenhouse(also called hothouse)is a building or complex in which allow for greater control over the growing environment of plants. Depending upon the technical specification of a greenhouse, key factors which may be controlled include temperature, levels of light and shade, irrigation, fertilizer application, and atmospheric humidity. Greenhouse may be used to overcome shortcomings in the growing qualities of a piece of land, such as a short growing season or poor light levels, greenhouses are often used for growing flowers, vegetables, fruits, transplants and seedlings. Greenhouses can be divided into glass greenhouses and plastic greenhouses. Plastics mostly used are polyethylene film and multiwall sheets of polycarbonate material, or PMMA acrylic glass. Commercial glass greenhouse are often high-tech production facilities for vegetables or flowers. The glass greenhouse are filled with equipment such as screening installations, heating, cooling and lighting, and may be automatically controlled by a computer.
