First, whole-of-the-ground fertilisation chooses the sandy sandy soil, which is deep in the ground, is rich in quality and lax in quality. The ground must be fine enough to sow, sow, soak, so that the soil can be made thin. Mainly based on fertilizer, it is supported by a combination of acreage application of 3,000 kg of fertilized farmers with appropriate quantitative fertilization。
It is appropriate to sow seeds at the appropriate time between the end of july and mid-august, before sowing, with 30 cm wide, 15 cm high and 20 cm wide. When the seedlings appear in two leafs, the seedlings take care to stay weak and strong, with two to three seedlings per cave and four to five seedlings。
3. The field management pre-growth period of the autumn radish is characterized by high temperatures and rainy seasons, in which weeds should be ploughed in a timely manner, with the principle of shallowness after deepness before shallowness, care not to damage roots, prevention of decaying roots or cracks, etc. Accelerator ammonium sulphate (ammonium sulphate) is followed up with water in a combination of 15-20 kg per acre and is applied 10 cm close to the sapling, with a 15-day interval followed by one to two urinations of 1,000 kg/acre each. The “breeding” of four to five seedlings should be preceded by less water to promote straight rooting. The surface of the top of the root of the flesh is exposed and attention should be paid to the application of fertilizing water with a thickness of almost 2 cm. The lack of water at this time can result in hollow, hard, spicy, and lower yields. Water was stopped 5-6 days before the harvest。
For maggots, 90 per cent of the crystal trichlorfon 500 times the fluid can be used to root maggots; 50 per cent of the thiophosphorus emulsifiable concentrate can be used to treat voodoo; 70 per cent of the acetylene acetylene can be treated with 2,000 times the hygienc powder; and 65 per cent of the dysene manganese zinc can be treated with 500-600 times the fluid。
