What is the planting method of windbreaks?

Land selection and soil preparation: Saposhnikovia divaricata is a deep-rooted plant, the main root length can reach 50-60 cm, and it is suitable to be planted in sandy loam with high dry terrain and good drainage; Clay land is planted with short windproof, many forks and poor quality. Saposhnikovia divaricata is a perennial plant, and sufficient base fertilizer should be applied for soil preparation, with 3000-4000 kg manure per mu, calcium superphosphate 15-20 kg, deep ploughing and fine harrowing. A flat ridge with a width of 1.3- 1.7m was made in the north, and a high ridge with a width of 1.3m and a ditch depth of 25cm was made in the rainy area in the south.

2. The propagation mode is mainly seed propagation, which can be sown in spring and autumn. Spring sowing, from late March to mid-April in the river basin and mid-April in North China; Sowing in autumn, September in the river basin-10, sowing before freezing in North China, and emergence in spring. In the finished border, furrows are dug according to the row spacing of 30-40cm, and the depth of furrows is 2cm. Sow the seeds evenly in the furrows, cover the soil and flatten it, slightly suppress it, cover the grass and water it to keep the soil moist, and the seedlings can emerge 20-25 days after sowing. 2 kilograms of seeds per mu.

3. Interplanting field management: when the height of seedlings is 5cm, the spacing between plants is 7cm; when the height of seedlings is 10- 13cm, the spacing between plants is 13cm.

The planting method mentioned above is the planting method of most of us, but in recent years, with the continuous progress of science and technology, our agricultural modernization has also been put on the agenda. Nowadays, many crops have begun to be sown and harvested mechanically, and many new machines have appeared on medicinal materials, which have played a great role in our planting. It is difficult to accurately control the amount of seeds. Planting management is very complicated, even in the late stage of mechanical sowing, it takes a lot of manpower and material resources to sow seedlings. Now there is a better planting method, that is, the seeds are pelleted twice.

Such seeds will become seeds with uniform size and smooth surface, which is more suitable for large-scale mechanized seeder sowing. So how did it do it? I have to mention our new seed granulator. It was the advent of this machine that completely changed the problem that medicinal materials could not be sown accurately. Seed pelleting is to change small seeds into large seeds, and irregular seeds into round or oval shapes, which is more suitable for mechanized planting. There are many machines to choose from. We can choose knitting machine or plug seeder according to the long characteristics of seeds. After the seeds are pelleted, they can be positioned quantitatively, saving seeds and costs. There is no need to transplant seedlings in a large area in the later stage, which saves a lot of manpower and material resources. Moreover, the seeds do not have the problem of competing for nutrients and sunshine, and the seedlings are even and Miao Zhuang.
