Soil conditions and seed quality
Soil conditions
Soil fertility above average, soil organic content of 1. 0%, soil nitrous content of 0. 1%, soil phosphorus content of 0. 10, soil
Quick effect phosphorus content 5. 0 mg/kg, soil potassium content 80 mg/kg and soil salt content 0. 3%. If this is not achieved, it will be possible
Overfertilizing supplements。
3. 2 seed quality

4 reproductive characteristics
4. 1 nutritional growth characteristics
The species is burgeoned and bred, and growing more rapidly, especially after the period and flowering; the leaves are large and the leaves are dark; leaf branch
Stronger, larger, loose。
4. 2 reproductive growth characteristics
The branch starts at about seven. It's fast, it's electric, it's bell-sharp, especially during the bell-sharp season
In the stronger case, the upper branch is still stretching fast and has a strong drinking capacity。
5 production structure
5. 1 production indicators
Production of more than 100 kg per 67 m3 skin
5. 2 production composition
More than 60. 0 million bells per 667 m2 total; average single bell weighing more than 4. 7 g: clothing above 37. 0 per cent

Plantation techniques
7. 1 oral selection
The varieties are suitable for cotton planting and lead to the selection of low-prematured high-yielding crop varieties such as garlic, melons and premature wheat. Whatever
The herd should be predominantly cotton, with more than 60 per cent cotton。
2 cultivate the seedlings
7. 2. 1 bed preparation
7, 2
Sapbed selection
The seedbeds are selected in areas close to the field, with no dead yellow atrophy, fertile soil, light and easy to manage. In the autumn, press every 67m daejeon
A standard seedbed (12 m ~ 15 m x 1. 33 m) and approximately 80 cm wide drains and walkways around it. Application of 150 per standard bed
200g murdan to prevent underground pests。
7. 2. 1. 2 fertilizer beds
Fertilizers of 4kg ~ 5kg per sapling bed, 2kg carbon ammonium, 3kg ~ 4kg per phosphate, 2kg potassium chloride. Fertilizer mixed with bed
7. 2. 1. 3 ribbon and ribbon
In mid-march, it's 7 cm in diameter, 9-10 cm in height
It is desirable that the earth's moisture be prepared in front of it, and that it be scattered at a height of 1 metre from the ground。
The number of scramblings should increase by 60-80 per cent compared to the density of the field's decomposition。
7. 2. 2 旙
