Greenhouse vegetable greenhouse has been a very common way to cultivate vegetables, in order to promote the development of agricultural economy, soilless cultivation in greenhouse is a new way to adapt to the development; Therefore, the soilless cultivation frame produced by green Zhixin soilless cultivation factory is very popular. In this small series, we also want to remind you how to build and operate soilless cultivation greenhouse!
First, choose the appropriate greenhouse film. Using greenhouse to grow vegetables is a common vegetable planting technology in China. Building greenhouses should take into account the growth needs of vegetables, reasonable use of greenhouse membrane, so that vegetables grow regularly. Choose the greenhouse film to consider the warmth and non-toxicity. With the improvement of people's education level and quality of life, more attention is paid to green diet, and green vegetables have become the focus of people's attention. When using greenhouse to grow vegetables, if the greenhouse membrane has certain toxicity, not only will hinder the normal growth of vegetables, but also make vegetables contain different degrees of toxic substances. In addition, attention should be paid to the assembly of the shed membrane, a good assembly quality shed membrane can make vegetables grow in the appropriate temperature and humidity conditions.
Two, control the light inside the greenhouse. Light is essential to the growth of vegetables. Without light, vegetables can't produce chlorophyll and can't grow properly. Therefore, when using greenhouse to grow vegetables, attention should be paid to control the light. The intensity of light varies greatly in different seasons. Generally, during the winter and early spring, there is less sunlight, and because the greenhouses are cut off from sunlight, the vegetables receive very little light. During this period, farmers should lift the mulch to ensure that vegetables get adequate sunlight. In addition, in order to ensure that the sunlight in the greenhouses can meet the growth needs of vegetables, some facilities and equipment can be installed in the greenhouses, such as small bulbs, so as to raise the temperature of the greenhouses.
Three, pay attention to ventilation. Greenhouse is almost a closed space, in this environment, vegetables themselves react, it is likely to produce some toxic gases, if not timely discharge of these gases, will hinder the normal growth of vegetables, timely ventilation can ensure the normal growth of vegetables.
Four, scientific selection of vegetable varieties. There are different types of vegetables, and different vegetables have different requirements for the environment. Growers should consider whether the local terrain can meet the growth needs of vegetables, whether the vegetable varieties can meet the market demand, and ensure that the vegetable varieties can improve farmers' income. Rather than excessive planting, resulting in poor sales, low cost sales, resulting in losses of farmers' economic interests.
Fifth, do a good job in the prevention of diseases and insect pests. Vegetables in one or more stages will be affected by diseases and insects, resulting in reduced production. Farmers planting vegetables should be observed in time to prevent the occurrence of diseases and insect pests, and take measures to eliminate diseases and insect pests, reduce the impact of diseases and insect pests to a lower level, while doing a good job of greenhouse cleaning.
Sixth, scientific irrigation. Water is a necessary condition for the growth of all things, the growth of vegetables need enough water, without water vegetables can not grow normally, or even directly die. Therefore, planting vegetables must be watered in time. In addition, the water requirement of vegetables in the different stages of growth also has certain differences, we should pay attention to this, scientific irrigation vegetable food is an essential part of people's life, this is because vegetables contain a variety of nutrients, vegetable cultivation techniques and key points of modern agriculture were analyzed, and the development of cultivation techniques, to improve people's quality of life, promote long-term, stable development of agriculture in China.
