Autumn stubble vegetables have entered the peak period of planting. Due to the tight time, they were planted without carefully checking the quality of the seedlings after the seedlings arrived. If problems such as diseased or weak seedlings are discovered after planting, it will cause a series of difficulties in later management. Therefore, when receiving seedlings, you should pay attention to whether the seedlings are neat and consistent, whether the seedlings are healthy, and whether they carry pests and diseases. You should not just check the quantity and ignore the quality. In addition, some large-scale and well-managed seedling plants will also have anti-counterfeiting marks. How to control ground maggots Ground maggots refer to all nymphaeidae larvae that damage the underground parts of open-field vegetables, also known as root maggots. They will feed on young vegetable stems, petiole bases, heart leaves, roots, bulbs and other places. After they develop into adults, they will gather on the incompletely decomposed manure. They are afraid of light and prefer to hide and damp. To control ground maggots, use 1.1% matrine powder 2 to 4 kg per mu, add 1000 to 2000 kg of water, and irrigate the roots along with the cultivation; or use 90% crystal trichlorfon 500 times liquid, 50% phoxim EC 800 Water the roots with ~1000 times liquid. Quickly decompose wet chicken manure Spread a layer of straw powder on the ground, and then spread wet chicken manure on it, sprinkle with 0.1% urea, sprinkle 15 kg of superphosphate per ton of straw powder, and sprinkle in a 0.2% quick rot agent premix. Straw powder can be used to adjust the humidity, and it is advisable to hold it into a dough. Turn the compost twice and pile it into a pile with a width of 1.5 to 2 meters, a height of about 1 meter, and an unlimited length. Use a stick to punch the air holes, and cover with a plastic sheet to keep moisture, heat and fertilizer. Other management is the same as that of dry chicken manure fermentation, and special attention should be paid to ventilation.
