Cucumbers, tomatoes, eggplants, and peppers grown in greenhouses have the advantages of rapid growth, early maturation, high yield, and good economic returns. The idea is that "good seedlings will be planted and good seedlings will be produced at high yields." Therefore, many vegetable farmers choose to keep their dishes in the greenhouse. In fact, this is not desirable. Because the temperature of vegetables growing in greenhouses is not consistent with the temperature of the outside world, vegetables in greenhouses are poor in stress resistance, pollination is low, and seed maturity is not high. Due to the limited area of ​​greenhouses, it is not easy to change the sorghum with seedlings, and pathogens that spread along with seeds and soil will be harmed in a cyclic manner. Therefore, to remind farmers to pay attention to friends, do not choose to stay in greenhouse vegetables, so as not to cause unnecessary losses in the next year planting.
