Weed residues Many vegetable farmers save trouble when turning over the ground, turning the residual plants and weeds in the shed into the ground. This is potentially harmful. First of all, these residual plants and weeds carry a lot of germs and eggs. Turning them into the ground will aggravate some soil-borne diseases (Phytophthora capsicum root rot, tomato blight, etc.) And whitefly occurrence; secondly, vegetable residues remain in the soil, and some autotoxic substances will be produced after rot. If the same vegetable is still planted in the next crop, it will affect its normal growth. It is recommended that all roots of the plant be pulled out of the soil when clearing the garden. When cleaning up the residual plants, the rotten fruits, fallen leaves in the planting rows, and weeds in and outside the shed should also be removed. The residual plants cleaned out of the shed should not be stacked near the shed, but should be transported to a special place to be stored or buried, so as to prevent pathogenic bacteria on the residual plants from entering the shed with wind, rain, insects or people. Manure should be fully rotten Vegetable farmers have the following problems when applying manure: First, the time for fresh manure to decompose is too short, ammonia and other toxic substances generated in the manure cannot be converted in time, and the vegetables are harmed after planting. Biological bacteria, harmful bacteria carried in manure, etc. may multiply in large quantities, and they are not completely rotten, which is prone to burn seedling problems. It is recommended that the application of manure should be based on the specific conditions of your own shed. If the planting time of the next stubble is approaching, you can add fermenting fungicide after the application of manure to increase the fermentation bacteria in the soil and accelerate the manure maturation. It is still far away, and it can cooperate with high-temperature shack to apply manure to the soil in advance to kill pathogenic bacteria and worm eggs carried in the manure to ensure that the manure is fully decomposed. To completely loosen the soil Vegetable farmers generally have the disadvantages of insufficient ploughing depth and small ploughing range when ploughing. First of all, at present, vegetable farmers generally use rotary tillers. After turning over the ground, they see that the soil layer is deep and loose. However, most of the actual rotary tillage depth is less than 20 cm. Turning the ground with this rotary tiller will cause the bottom of the plough to move up. The soil permeability decreases, the range of root growth is limited, and it is not conducive to the growth of vegetables. Second, in order to save trouble, many vegetable farmers only plow the cultivation rows, and the ridges are not plowed. Because these ridges have been stepped on for a long time, the soil is firm and restricted. The growth of the root system is not conducive to the cultivation of strong trees. It is recommended to try to plough the soil artificially with plow or iron hoe as much as possible. In recent years, many vegetable farmers have specialized small excavators to plow the ground. The ploughing depth can reach 50 cm, which effectively solves the problem of shallow ploughing. The soil should be deeply plowed every 2-3 years. When plowing, the ridges should be plowed together as much as possible to completely loosen the soil and facilitate the expansion of the vegetable root system. Pest control needs to be in place The crop replacement period is a good time for pest control, but most vegetable farmers often ignore this when turning over the ground. Many vegetable farmers now share a rotary tiller or hire someone to turn over the ground. If the rotary tiller is not disinfected before use, it will spread germs and pests in one shed to other sheds, especially root-knot nematodes. The spread of dirt on the soles of the shoes is very harmful. It is recommended that vegetable farmers do disinfection work when cleaning rotary cultivators and clean up the soil on the machines. In areas where the root-knot nematode is severely damaged in the shed, marks should be made when turning over the ground, and deep-turning with iron cymbals alone or at last, to avoid the spread of root-knot nematodes. Many vegetable farmers open the vents on the front and top of the shed after they turn over the ground, thinking that there are no vegetables in the shed, and pests will not enter. But this season is still harmful insects, they are likely to enter the shed to lay eggs, and then harm the next crop. Experts recommend setting up insect nets in time after turning over the ground to prevent outside pests from entering the shed, especially the vent in the front of the shed. Weeds around the shed should be removed in time to prevent it from becoming a transfer station for pests to invade the shed.
