Tobacco planting technology
1. Site preparation
Pre-winter deep plowing, ridging before spring planting, ridge distance 80 cm, ridge height 25-30 cm, it is recommended to plant a single row of ridges, buckwheat and tobacco should smash irrigated wheat ridge rot. With the use of ridges to use granular ground pest medicine, 80 kg of pure sulfur-based high-potassium fertilizer and 50 kg of bio-organic fertilizer are used per mu.
2. Planting seedlings
Single ridge single row of spring potato five meters, summer potato six meters, that is, an acre of 3,000 spring potato, summer potato about 3500 planting seedlings, it is recommended oblique planting or flat planting, prohibited direct planting.
3. spraying closed medicine
Within three days after the seedlings are sprayed, a safe and highly effective pendimethalin or isopropamide is sprayed against the sweet potato seedlings, a sprayer is 70-100 ml, and an acre sprayer is used. The effective period of 45 days basically avoids mid-term herbicides. If the sealing effect is not good, sweet potato special post-emergence herbicides can be sprayed.
4. timely control
1 Scorpion 25 centimeters first light control, sweet potato special control Wang medicine a bottle of a mu.
2 tweezers 35 centimeters to control the second time.
3 The third time after a week, control Wang.
5. With the control of spraying foliar fertilizer
The enhanced taste combined with the control of spraying special potassium dihydrogen phosphate sweet potato, increase color with drip irrigation drip trace elements, increase production of spraying photosynthetic production factors, increase storage resistance spraying sweet potato calcium and preservatives.
6. Killing harvest
Tobacco 25 needs to be stored before harvesting, storage temperature is 7-10 degrees, humidity is 75-95%, and sufficient oxygen supply is maintained. Therefore, it is necessary to pick out the broken insects. Nicotine 25 electricity supplier specifications two to six two, two or two to two pounds of grilled potato specs six or two catty, all require no disease pest trenches.
