There are many advantages to laying crop stalks in greenhouses. On the one hand, it can increase the temperature inside the shed and has the effect of heat preservation and warming. On the other hand, it can effectively reduce the humidity in sheds and reduce the chance of vegetable infection. There are also some stresses on the laying of crop stalks in greenhouses. Specifically, there are the following points:

1. Select the appropriate crop straw. For North China's grain-producing areas, the stalks of wheat, corn, rice, and other gramineous crops are rich in cellulose, good in straw flexibility, and good in adsorption, and can be laid in sheds. These straws can also be used as high-quality farmyard fertilizers after fermentation by high temperature or microbial action.

2. High-temperature exposure to straw. Above the crop stalks are often attached to or parasitized pests eggs or pathogens, should be selected sunny weather, the crop stalks laid on flat land or concrete ground full exposure for 2-3 days during the period, use iron forks to turn the sun, so that crops Straw is fully dried.

3. Drug spray treatment. After the fully stalked crop stalk is evenly distributed, a 1,000-fold potassium permanganate solution or 50% carbendazim 500-fold solution is used, and phoxim 800-fold solution is added. After the mixture is uniformly mixed, the crop stalks are sprayed. Further eliminate pests or germs remaining on the straw. After the crop stalks were filed neatly, and the plastic film was overwhelmed two days later, the stalks could be transported directly to the shed and placed in the operation line.
