The quality of organic fertilizers should meet the requirements of ny525, and the quality of fertilizers should meet the requirements of ny/t496。

It is appropriate to apply a mechanically lax approach to the ground, with a depth of 25 cm to 30 cm in the field, to flattening, to make deep trenches of 1. 5 m to 1. 8 m wide, 20 cm to 25 cm high and 30 cm to 40 cm wide。
Five
5. 1 selection
The selection of varieties suitable for local cultivation, with seeds free of moths, imperviousness, light and full seed capacity, 80 per cent pure seed, 80 per cent clean, water content and gerontology levels are excellent。
5. 2 period
It's suitable for march to july。
5. 3 volume
For each 667 m2 broadcast during the broadcasting cycle, the volume may be increased appropriately if the site is of poor quality or delayed。
5. 4 sowing methods
Seed-breeding is used to sow the seed from impregnated seed in a wind-free weather in a thin, dry sanded bed of 1:100
Two times。
Six plants
6. 1 deplanting time
It's 40d-50d, 5cm-7cm, and it's four-five leafs. It is advisable to choose whether to move in the rainy weather or in the evening。
6. 2 cultivation density
Plant 8,000 to 14,000 plants per 667 m2 at 25 cm x 20 cm. 6. 3 emplacement
Caves, 1 puddle, grounded and watered。
7 field management
7. 1 saplings
Four centimetres of time and two to three saplings at 15 to 20 centimetres. 7. 2 shrimp
Following the transfer, 5d-7d seedlings were replaced, and a shortage was found to be timely。
7. 3 cropping
A full-scale weeding, pine earth before the closure. A little of the red root is shallow, so that it tends to be shallow, so that it does not hurt the root. Artificial weed after sealing。
7. 4 chase fat
A little red for fresh food followed by urea 25 kg per 667 m2 after every harvest combined with water to fatten。
A little red-coloured farming followed by compound fertilizer of 15 kg ~ 20 kg per 667 m2. Fertilizer quality should meet the requirements of ny/t496. 7. 5 drainage
After planting, water is poured in time to keep the soil wet. Water should be drained in time for heavy rains。
