(c) land selection: the choice of areas with strong drainage, sufficient light and fertile soil for cultivation。
When the land is completely levelled, the land will be levelled and the ditch will be opened。
Irrigated fertilization: during different periods of growth, water, drainage, fertilization etc. Are performed in a timely manner。
Sowing: mainly sowing and shifting。
Preventive measuresPrevention of white powder with cactus, treatment of plaster with dyson zinc or bodol spray, use of trichlorfon to kill silver moths, and use of fruit milk to kill red spiders。
I. Election of the land
1. Land selection: the choice of areas with strong drainage, sufficient light and fertile soil for cultivation。
Land degradation: in order to facilitate drainage, it is necessary first to level the land and then to open the ditch。
Ii. Fertilizing irrigation
1. Water and drainage is done in a timely manner after planting and during periods of growth。
Before seeding, in order to increase soil fertility, it is necessary to fertilize in the soil and work as a base。
3. At 15-20 cm, it is not appropriate to carry out fat pursuits to sow leaves。
Iii. Scrolling methods
1. Seeding time: the choice is made after or soon after rain。

3. After seeding, water is done in time for drainage during the rainy season。
Iv. Preventive measures
Main diseases: dust, stale diseases. Main pests: red spiders, silver moths。
2. Prevention and treatment of pollinosis: using pixie and high spraying。
3. Prevention and treatment of scavenging: reasonable planting density, adequate light, maintenance of soil moisture, effective protection against scabs, use of dyson zinc or podol spraying in case of disease。
4. Elimination of silver moths: use of trichlorfon to spray。
5. The elimination of red spiders: the use of fruit milk sprays。
