[Scientific planting hundred questions and hundreds of questions] How to reduce the seedlings?

Question: How to reduce the erosion between the erosion?

** Answer: ** Mo seeds are small, thousands of grains weigh 6 ~ 8 grams, 1.67 million to 1.67 million seeds per kilogram, and 30,000 to 40,000 seedlings per acre.The traditional meal sowing method is not easy to control the amount of sowing. The amount of seeds per acre is generally 0.6 to 1 kg. Based on the 80%of the seedling rate, the seedling varieties are 60,000 to 80,000 plants, and the seedlings of small granules are from 80,000 to 130,000 to 130,000.The strain.In order to reduce the amount of work and reduce the labor intensity, before sowing, take 25% to 30% of the seeds of the seeds for 10 minutes with boiling water.Workers of Mori seedlings.

For conditions, the amount of seeding can be mechanized. The amount of sowing per acre is 0.2 ~ 0.3 kg, the machine broadcast spacing is 33 cm, the acupoint distance is 4 ~ 5 cm, and each hole is 2 to 3 capsules.
