Analysis of key points of modern agricultural vegetable cultivation technology

At present, China's cultivation technology has been significantly improved to a certain extent, and it has gradually formed a unique set of technologies and management processes for different types of local vegetables, such as cultivation varieties, water and fertilizer management, so as to promote the smooth realization of standardized production.

Present situation of modern agricultural technology

Today, with the increasing development of agricultural plastic greenhouse technology in China, the role of greenhouse in modern agricultural vegetable cultivation technology has gradually become prominent, and it has brought a very far-reaching impact on the construction of modern agricultural system.

The choice of shed film

Because the ultimate purpose of the selection of the shed film is to be able to plant no pollution, no drop performance of good vegetables, because the shed film as a whole has a very good light transmittance, therefore, to a certain extent, to increase the light required for vegetable growth, which is compared with the general quality of agricultural film, the shed film can well promote the increase in vegetable production and value, at present, Non-drop thermal insulation anti-aging film and high thermal insulation non-drop anti-aging film are the most widely used in China.

Illumination control

"All things grow by the sun" this is a well-known simple truth. In the normal growth process of vegetables, light is a very important factor affecting the final yield and quality of vegetables, light intensity can have a direct impact, therefore, at the same time we should effectively use natural light, while artificial light can be used to promote vegetable production has been significantly increased.

Take timely ventilation measures

Shading in the case of no ventilation can well promote the temperature in the greenhouse to reduce by about 5°, effective ventilation can not only promote the temperature in the greenhouse to be significantly reduced, but also ensure that the air in the shed is maintained in a good circulation state, and other harmful gases are eliminated in the first time. In this way, the probability of vegetable diseases in the shed will be well reduced. In addition, it can also play a role in improving vegetable photosynthesis and increasing vegetable yield. During the ventilation process, we must pay attention to the position of the vent to avoid the wind, to constantly change the orientation of the vent, and to ensure the change of the ventilation volume, and not to rapidly reduce the temperature at the position of the vent.

The choice of strong seedlings

In the process of planting vegetables, some can be directly sown, most of the vegetables need to be pre-cultivated and transplanted, like some melon and fruit types of vegetables are required to be cultivated, only the choice of strong seedlings can achieve the ultimate goal of high yield and efficiency.

Fertilization requirement

In the fertilization operation, organic fertilizer is usually the main fertilizer, and some base fertilizer can be applied appropriately. However, the entire process of fertilization must be in accordance with the category of vegetables, soil conditions, etc., to select the most appropriate type of fertilization, to ensure the appropriate amount of fertilization. In addition, be sure to ensure the ventilation and air permeability of the soil in the vegetable growing area. Usually when fertilizing vegetables, it is best not to use base fertilizer or topdressing for a long time, we can add an appropriate amount of trace elements in the fertilizer to ensure that the fertilizer as a whole reaches a balanced state.

With the rapid development of modern agricultural vegetable cultivation technology, people's quality of life has been significantly increased, however, in the current pollution phenomenon is increasingly serious, serious shortage of land resources and other realistic conditions, how to promote the continuous improvement of vegetable cultivation technology, promote the quality of vegetables and production continue to increase, is the agricultural technicians shoulder the eternal responsibility.
