Trend 2 from the open cultivation to the protection of the cultivation and development: the protection of the cultivation of greenhouses, greenhouses, multi-layer coverage, net sheds, shade and so on. The cultivation of open field is affected by the early spring climate, and the output is not stable. Although the investment is small, easy to plant, well managed, the cultivation area is large, and the listing is concentrated, the issue of seasonal surplus is prominent.
The trend of three from the single-season cultivation to the annual cultivation and development: In the past to solve the early spring or late autumn vegetable market off-season, often use some early or very early varieties, in the short-term produce off-season vegetables, and in the short-term market. These varieties are often resistant, poor quality, low yield, short growth period. With the improvement of productivity, how to extend the production season, or to carry out annual production, the product has a long time to market, good quality and high output, and has become a market trend.
Trend 4 grows from single planting to multi-level cultivation: In order to make full use of the existing cultivated land and the space within the protected area, intercropping, interplanting, multiple cropping, multi-cultivation and multi-layer cultivation are often conducted according to the vegetable production situation. Such as tomato intercropping watermelon, intercropping leaf vegetables, mushrooms, pepper interplanting leeks, leeks or melon, melons and vegetables interplanting ginger, etc., in order to obtain a stable high yield.
Trend 5: From the group benefit to the pursuit of three-dimensional cultivation and development: With the development of science and technology, the high yield of single plant of vegetables has been improved, and higher yields and benefits can also be obtained through thin planting and three-dimensional cultivation.
Trend 6: From decentralized production to intensive production: From decentralized small-scale farming operations to centralized and contiguous planting, it is conducive to the popularization and application of new technologies and the mass processing, storage, transportation and sales of products.
Trend 7 shifts from labor-intensive to technology-intensive production: microcomputer control technology, drip irrigation, micro-irrigation technology, automatic roll-up blinds, automatic temperature control and light control, insect pollination, insecticidal lamp pest control, and pest control network pest control technologies. Reduce labor intensity and increase production efficiency.
