    Because this seedbed substrate fertilizer contains insecticide components. It can control all kinds of pests at the source. That's basically how we grow out-of-season vegetables now.

    Don't think that the fees have increased, but the benefits and benefits that come are beyond your imagination. It's okay to plant a small area, but a large area is a big expense. This method reduces to a certain extent many unnecessary troubles in growing high-quality cabbage.

    When the soil moisture is not good and affects the growth of cabbage, it is necessary to water the cabbage. Taking into account the nutritional growth requirements of cabbage, it is best to use the farmer's fertilizer when watering.

    But now this demand is basically not satisfied. Because there is no such demand and supply when planting large areas, it is even more difficult that there is no such human resources in rural areas, and there is a serious shortage of labor supply. Therefore, in many cases, water is watered.

    At this time, a certain amount of insecticide is mixed in clean water to achieve a good insecticidal effect. Cool weather after the autumn equinox is the key to the growth of cabbage, so it is important to do a good job of field management of cabbage. The biggest headache for vegetable farmers in cabbage field management is the gnawing of cabbage.

    Many pesticides are not curable. This is the result that even if the medicinal properties are passed, if the cabbage is pickled again, the cabbage will decrease, the quality of the cabbage will decrease, the quality of the product is not good, and it is not easy to sell.

    The effect of stocking Chinese cabbage insects with farmhouse grass and wood is very good. I have been using this method for many years. The specific method is to spread the prepared plants and trees evenly on the cabbage leaves after the dew starts to dew in the evening on a sunny morning, and it is difficult to stick the plants and trees firmly to the cabbage leaves.

    When vegetable insects gnaw on the leaves, insect pests often occur in the process of cabbage planting, which will not only affect the quality of goods, reduce economic benefits, but also cause many viral diseases. The control of vegetable green insects and other pests can preserve the high yield and economic benefits of cabbage. The liberated area of cabbage insects should take "prevention first, comprehensive prevention and control" as the principle, strengthen field management, cultivate healthy and good-looking products, and meet the market demand of the mayor.

    At present, the prevention methods of vegetable green worms are mainly traditional physical methods, biological control and modern chemical prevention measures that are being developed.

    The physical control methods of vegetable green worms were to select excellent cabbage varieties, mainly insect and disease resistant varieties, such as Qingza No. 3, Fenghang No. 78, Benzhai No. 3, Taiyuan Liqing and other varieties. Full cleanliness and soil disinfection are also key to preventing vegetable green worms. Light insecticide is the most environmentally friendly method, and the ideal method is to trap with frequency vibration insecticidal lamps or black lights to deal with vegetable green insects and other pests.

    Biological control methods of vegetable green insects In the process of cabbage planting, biological products and beneficial biological agents pest control, no pesticide residues, no pesticide pollution, and high safety are the main directions of pest control in the future. Vegetable green worms are detected early, easier to prevent, and can be sprayed with a solution of 300 500 times a day, and the prevention effect is very good when the insects have not yet developed resistance.

    According to the Ministry of Agriculture's vegetable common pest control technology and many years of experience in agricultural stores, planting Chinese cabbage cabbage is serious, and we have the following methods to control cabbage. The cabbage butterfly is also known as the cabbage white butterfly, and the young insect is called the cabbage green worm. The cabbage worm mainly eats the mesophyll on the back of the leaves, and we often see many holes in the leaves of Chinese cabbage, which is caused by the typical cabbage insect.

    As the cabbage worm grows, it will discharge a large amount of feces, contaminating the leaves and cabbage sum, resulting in poor quality of Chinese cabbage and easy to breed soft rot. Generally speaking, autumn is the peak period for cabbage worm damage.

    My family often plants a row or two of garlic or onions around the cabbage patch.

    Years of practice have proved that if you plant onions or garlic on the edge of the cabbage field, the cabbage will grow very well, and if you don't do any other control work, you will hardly see the shadow of pests.

    Of course, the control of cabbage insects can also be killed with pesticides.
