Vegetables such as cucumbers, tomatoes, eggplants, and peppers grown in greenhouses have the advantages of rapid growth, early maturation, high yield, and good economic returns. As a result, some vegetable farmers thought that "good seedlings should be planted and good seedlings should be produced at high yields." In fact, this is not desirable.
Because the temperature of vegetables growing in the greenhouse is not consistent with the outside temperature, the vegetables in the greenhouse are poor in stress resistance, low in pollination, and low in seed maturity. 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, it reminded the vegetable farmers not to use greenhouse vegetables to plant seeds.
