Recently, a farmer sent a private letter asking how to use the idle greenhouse in summer? Indeed, in the hot summer, the temperature in the greenhouse is high, which is not suitable for the growth of general crops, and most of them are idle, resultin.
Grow vegetables
In summer, it is hot and rainy. Use solar greenhouses or greenhouses to grow spinach during idle time in summer. One crop can be harvested in about 40 days. The yield per mu is more than 2,000 kilograms, and the income is considerable. Spinach likes fertile, moist soil with high organic matter content. Apply appropriate amount of decomposed organic fertilizer according to soil quality. If it is in a solar greenhouse, no base fertilizer can be applied.
Using the idle greenhouse facilities in summer (ordinary steel frame greenhouses), a set of non-woven fabrics as a matrix and a three-dimensional hydroponic system with high efficiency facilities are designed to produce multiple crops of safe and high-quality small greens. The PPR drinking water pipeline (20~30 mm in diameter) can be fixed with north-south brackets on the upper and middle bars of the steel tube greenhouse, or no brackets are provided, and the middle hanging wire can be used for fixing. Six north-south pipelines can be installed in the 6m greenhouse. Poke a water outlet hole (about 1mm in diameter) every 5-8 cm, and connect it to the liquid storage tank with a three-way or four-way pipe. On the one hand, the PPR pipe is used as a fixed support for the non-woven matrix; on the other hand, it is used as an integrated drip irrigation pipe for water and fertilizer. Non-woven fabrics are hung on both sides of the PPR pipeline as a fixed substrate for cultivation roots, and covered on the water outlet holes, and the outside of the greenhouse is covered with insect-proof nets and sunshade nets.
Grow fruit
When using rice seedlings to grow in greenhouses, the primary consideration is to choose varieties that do not affect rice seedlings. The study found that the soil nutrients required for strawberries are basically the same as those required for rice seedling raising. As long as the infrastructure of the rice seedling raising greenhouse is fully utilized after the rice seedling raising is completed, high-yield and highly commercial strawberries can be cultivated. benefit. After harvesting strawberries, it is only necessary to crush and level the soil inside the greenhouse, which will not affect the use of rice seedlings in the second year.
