1. Land selection: the choice is to grow in sandy sandy soil with strong drainage, estuarine and soil thickness. 2. In the field as a whole, 2500 to 5,000 kg of decomposition fertilizer per acre after three to five times of tilling soil. Seeding: the planting takes place before the rainy season during spring. In the autumn, planting was chosen in august. 5 field management: the timely preparation of seedlings, weeding, fertilization, etc., depending on the growth of the seedlings. 6 insects and pests: root-scraping with tobuzin or polybacterial spirits。
I. Election of the land
1. The choice is to grow in sandy soils with strong drainage, estuarine and thicker soil。
Before planting, three to five times the soil is tilled and then 2500 to 5,000 kg of decomposition fertilizers per acre are spilled into the soil。
3. After fertilization, the width of 1 - 1. 2 m is applied。
Ii. Sowning
1. Plantation methods: seed reproduction. Seeding methods: spring, autumn。
2 spring
The wet soil areas should be broadcast in spring before the rainy season。
Seeds are first immersed in water around 30°c for 24 hours, then dryed and then planted。
3 autumn
Seeding time: august, sowing density: 0. 7-1kg per acre。
When seeding takes place, it is broadcast on a 50 cm ditch on the side of the stairwell, then covered with three to five cm of earth and then crushed。
Iii. Field management
Following seedlings, and in conjunction with the growth of the seedlings, work is done in a timely manner on seedlings, weeding, etc。
2. Fertilisation
Nitrogen fertilization in the pre-growth period and potassium phosphate fertilization in the post-growth period。
Every spring festival, before the rain, weeding and fertilization work is carried out, with fertilizers choosing 50-100 kg of corroded cortex per acre and 1,000-1500 kg of farm fat。
After two years of growth, there is a need to remove non-stilled flowers。
Iv. Pests and pests
1. Main diseases: root causes, major pests: aphids, silver moths, grasshoppers, etc。
The precautionary approach
In the early stages of the onset of the disease, root causes of the disease were prevented by spraying with the root of the tobuzin or polybacterial spirit。
Timely drainage during the rainy season can effectively avoid root causes。
Pest prevention needs to be combined with agricultural, physical and chemical control。
