With the rapid development of modern agriculture, there are more and more planting methods. At present, the most planted households use greenhouse greenhouses, but there are also drawbacks in greenhouse cultivation. For example, the soil is easy to be knotted. Today, Huinong.com will share it. In the solar greenhouse soil improvement and fertilization repair technology, growers quickly learn! The continuous production cycle of the solar greenhouse is long, the soil can not be rested and rested, and it is easy to “fatigueâ€. In addition, the use of solar greenhouse fertilizers and pesticides is large, the soil loses the chance of natural freezing and thawing and leaching, and the cultivated soil is easy to be knotted and salted. Water staining. Improvement, fertilization and restoration of greenhouse soils are important measures to maintain greenhouse productivity. Soil improvement and fertilization repair technology in solar greenhouse: First, the rotation is down . The solar greenhouse should often be rotated between different vegetables and fruits to balance the ground force. It is also possible to plant a high-yield crop such as corn for feeding in the summer when the high temperature is in the high temperature period. After the seedling grows for about 40 days, it can be harvested or deep-pressed to achieve the purpose of lodging or biological cultivation. Second, the combination of breeding and breeding. Entering the summer period, the solar greenhouse cleans the litter after the crop is harvested, leveles the land, and combines the farmer's fertilizer to deep turn and ridge for 20 to 30 days to make the soil rest and recuperate. It is also possible to plant peas and other land-raising crops during the high temperature period in summer, and the seedlings grow for about 40 days, then deep-pressed and pressed, and cultivated and fertilized. Third, large water pressure salt. The solar greenhouse is a relatively closed small environment. Due to the large amount of fertilizer applied during the growing period of the crop, and the long-term lack of natural rainfall leaching, the ploughed soil tends to accumulate salt and make the soil secondary to salinization. Using the high-temperature production gap in summer, the soil in the greenhouse is flooded 1 or 2 times, and the salt accumulated in the plough layer is leached to the deep layer of the soil. Fourth, the high temperature shack. The so-called high temperature shack is the use of sunlight and drug fumigation for shed sterilization. In the summer period, taking high temperature shacks can not only mature the soil, increase the organic matter content, improve the soil structure, but also eliminate germs, kill eggs and remove weeds. It is a good way to improve greenhouse soil. Specific practice: after the summer greenhouse period crops are pulled, the crop leaves are removed, the soil is leveled and the soil is fined, and the farm manure such as chicken manure, pig manure and sheep manure is applied to the soil together with the soil preparation. After deep squatting, the ridges are ridged or made into high and low ridges according to the method of cultivating the crops. For the sheds with dead trees in previous years, use 50% carbendazim powder 2 to 3 kg plus 10 times fine before ridges. Mix well and spread evenly on the ground and evenly plow 10 to 15 cm to disinfect the soil. Before sealing the greenhouse, spray a fungicide and insecticide on the surface of the shed to kill the bacteria hiding in the gap. And pests; foot water irrigation, so that the soil water content reaches 60% of the maximum water holding capacity in the field; cover the ground with mulch film (fine crop straw), strictly close the greenhouse, keep the insulation as much as possible at night, keep it for 20 to 30 days, condition permit The time for the shack can be extended to 40 to 50 days. Everyone knows that whether it is vegetable cultivation or flower planting, the soil is the key, then the small-scale finishing of the above-mentioned solar greenhouse soil improvement and fertilization repair technology, the growers are rushing to collect it!
