If the greenhouse vegetables mainly grow melons, the vegetables are best ridged in the greenhouse, and planted in large and small ditches. First, ridge planting can increase the tillage layer, increase the ground temperature, and ensure root growth; second, the watering capacity is well controlled to prevent damage to the roots; third, the ditch is convenient for farming operations, improving the ventilation and light transmission between the rows. It can have the effect of preventing disease and increasing production.
Then how to adjust the ditch and ridge, carry out the cultivation of large and small ditch, and the Hui Nong School here brings a simple and practical way for everyone.
1. The width of a greenhouse is about 3.6 meters. It is suitable to plant 5-6 ditch vegetables for each plant. You can estimate this value according to this value.
2. Use a tape measure to measure the line from each column position. The width between the two lines is preferably 60 cm or 72 cm, which is the line spacing. Divide the adjacent two columns into planting rows;
3. Use the big hoe to open the ditch and cover the soil, and grasp the principle that the planting line and the operation line are in phase. When planting rows are covered with soil, the soil is covered from the planning line to the outside to form a “small and small ditchâ€;
4. After ditching and covering the soil, use the hoe to level the operation line and the planting line separately, and keep the ridge height about 25-30 cm. When planting vegetables in later stages, planting at half ridge is most suitable;
In four simple steps, the work of adjusting the ridges and ridges can be completed, and the production of greenhouse vegetables can be increased.
