Paddy-upland rotation planting method of greenhouse potherbs

Abstract

The invention discloses a paddy-upland rotation planting method of greenhouse potherbs. The method includes the following steps: selecting a first potherb variety from land potherb varieties to plant in a greenhouse; selecting a second potherb variety from the land potherb varieties, and interplanting the second potherb variety and the first potherb variety in the greenhouse; selecting a third potherb variety from the land potherb varieties, and applying fertilizer and interplanting the third potherb variety in row spacing after the first potherb variety stops growing and before the first potherb variety is eradicated; after the third potherb variety germinates, eradiating the first potherb variety; after the second potherb variety stops growing, eradiating the second potherb variety and planting the third potherb variety; after the third potherb variety stops growing, selecting a fourth potherb variety form the land potherb varieties, and building shallow water layers to transplant the fourth potherb variety after applying fertilizer; after the fourth potherb variety stops growing, selecting a fifth potherb variety from aquatic potherb varieties to plant; after the fifth potherb variety stops growing, repeated the above steps to plant circularly.

Description

technical field [0001] The invention relates to a planting technology of crops, in particular to a planting method of wild vegetables in a greenhouse in water and dry rotation. Background technique [0002] Vegetable cultivation in facility greenhouses is more profitable, but after three to five years of continuous planting of land vegetables, the soil in the sheds will not receive rainwater for many years, and the soil surface is prone to salinization, and severe salinity can be seen on the surface of the ground. Coupled with the long-term accumulation of diseases and insect pests, the land vegetables have suffered a serious reduction in production, reduced profitability, and even operating losses. Contents of the invention [0003] In view of the difficulty in planting land vegetables in the prior art above, the purpose of the present invention is to provide a method that can avoid such disasters and avoid soil salinization by using the method of rotation of aquatic vege...

Problems solved by technology

[0002] Vegetable cultivation in facility greenhouses has high benefits, but after three to five years of continuous planting of land vegetables, the soil in the sheds will not receive rainwater for many years, and the soil surface is prone to salinization, and severe salinity can be seen on the surface of the ground.

In addition, the long-term accumulation of diseases and insect pests has caused serious reductions in land vegetable production, reduced profitability, and even operating losses.
