The arrangement of vegetable stubble in greenhouse should be reasonable

The stubble arrangement of vegetables in greenhouse must adapt to the market, adjust measures to local conditions and greenhouse system.

Generally speaking, the following principles should be grasped in the arrangement of stubble:

First, according to the market price, the peak period of vegetable harvest is arranged in the period with the highest vegetable price.

Second, the ripening period of vegetables is arranged in the most suitable season for vegetable growth. only by combining high yield with high price can we achieve high benefits and reduce the difficulty of management and production losses. In fact, if the greenhouse with poor thermal insulation performance is produced twice a year, that is, winter and spring and autumn and winter, and make full use of the light and heat resources from March to June and September to November, high yield and high efficiency can also be obtained.

The third is to improve the utilization rate of the greenhouse. There is a problem of "summer leisure" in the winter warm greenhouse and "winter leisure" in the arch greenhouse. Straw mushrooms and beans can be cultivated in the winter warm greenhouse during the summer off stubble, and rape and spinach can be planted in the arch greenhouse during the winter idle period, which can effectively improve the planting efficiency.

Fourth, it is necessary to consider crop rotation with other vegetables to reduce diseases and insect pests and prevent soil secondary salinization.
