Many vegetable farmers have severely reduced production due to soil-borne diseases, and some have never stopped! Since we want to get the most benefit from the soil, we develop the soil and use a lot of chemical fertilizers, so that the beneficial bacteria in the soil are greatly reduced, the soil is compacted, and the vegetable greenhouse soil is a hotbed of various pathogens, which is the source of the survival of vegetables!
The greenhouse has been continuously planted for 5 years, and the soil bacteria are tens of millions. With the continuous improvement of the multi-cropping index of greenhouse vegetables, the soil-borne diseases have become more and more serious, which has become a constraint to the safe development of vegetable production.
The hot season is a good time to relax and slumber, prevent and prevent pests and diseases. If the growers can scientifically use the shack method, they can achieve twice the result with half the effort in the prevention and control of pests and diseases. This is a good way to eliminate germs, kill eggs, remove weeds, and improve the soil.
The so-called high temperature shack is the use of the sun's high temperature and drug fumigation for shed sterilization, generally from late July to mid-August. This method is low in cost, small in pollution, simple in operation, good in effect, and easily accepted by the masses.
The benefits of high temperature shack
(1) It is conducive to killing germs and insect sources.
(2) It is conducive to improving the efficiency of organic fertilizer. In order to improve the level of harmless and standardized cultivation, the majority of growers have increased the use of organic manure such as chicken manure, cattle and horse manure, and through the high temperature shack, it is beneficial to the post-fermentation of organic fertilizer.
(3) It is beneficial to improve the efficacy and no residue. By applying appropriate low-toxic, low-residue, photolytic, and volatile pesticides in the leisure shed, it is possible to increase the dosage in an appropriate amount, improve the efficacy, and fully exert the effect of high temperature and strong light, and shorten the residual period of the pesticide. To achieve harmless and non-residual effects on crops.
(4) It is conducive to raising land and fertilizing soil. Combined with increasing the amount of organic fertilizer and straw used, and scientifically applying a certain amount of fermented bacterial fertilizer, the soil structure can be greatly improved, the agglomerate structure can be enriched, the compaction can be reduced, and the degree of salinization can be alleviated and delayed.
Precautions for high temperature shack
(1) When applying the base fertilizer before the shacks, do not apply the biological fertilizer together to the vegetable greenhouse. If the biological fertilizer is applied before the suffocating shed, the biological bacteria in the bacterial fertilizer will inevitably be killed by the burning temperature during the high temperature suffocating process, and the biological bacterial fertilizer should not play the role.
(2) Under normal circumstances, the greenhouse greenhouse film is changed once a year. The vegetable farmers can deepen the shed in time after the gardening of the spring sorghum vegetables, apply the chicken manure, and use the old film to swell in the high temperature. Extend the shack time, but even if the shed time is a little longer, it is no problem, because the old shed film has already been changed, and the new film can be changed after the shed.
(3) Greenhouse greenhouses with serious root-knot nematode disease in vegetable greenhouses should be transported out of the shed before the high temperature shack.
(4) Many vegetable farmers apply all the fertilizers to the greenhouses, including biological fertilizers, in the base fertilizer, which is obviously not correct. Some vegetable farmers even after applying the base fertilizer containing biological bacterial fertilizer, not only the high temperature suffocating shed but also the methyl bromide fumigation, this practice is even more not worth promoting.
(5) With the new membrane, although the temperature is fast, the membrane damage is also serious, so the shed time should be controlled. After the general suffocation, put on a new film, wet for 15 days. For some old sheds, the shed time can be a little longer, but try not to exceed 20 days.
