In addition, before soil preparation, 667m2 needs to apply organic fertilizer about 400kg, phosphate fertilizer about 20kg and so on. Do a good job of deep ploughing, leveling the land, and timely removal of weeds and waste agricultural film and so on.

In general, the greenhouse does not need to be too large, the best scope is that people can work inside, adhere to the principle of low cost, from the direction of the shed, the best direction should be east-west direction. In general, the width of the shed should be 2.2 to 2.4m, and the length of the shed should be managed rationally according to the size of the plot.

3. Bed management

Flat bed or low bed is OK, but the width should be controlled at about 1m, and the length should be managed by combining the length of greenhouse, the number of seedlings and other factors. Under normal circumstances, it is necessary to set up two strip beds in a greenhouse and leave a path in the middle. After making the bed, rake the bed flat and cover it with fine sand (or vermiculite), which is usually 6~8cm in width. Next, it is necessary to install the plug-in advanced micro-spraying equipment reasonably at the top of the seedbed. In general, the number of sprinklers should adhere to the principle of no weight and no leakage in the spraying process.

When managing panicle production, the relevant staff should choose the plants that are 2 to 3 years old without diseases and insect pests and whose growth is more robust as the mother tree. Then the cuttings were made from late June to early July. After cutting the ear, try not to see the sun. After cutting the ear, you should not soak it in water. You should immediately start to make ear without light, that is, make rational use of branches. Generally, the ear should be controlled in 10~15cm, and 2-3 buds should be retained in each branch. The distance between the upper cut and the apical bud was controlled to 0.5cm, and the flat cutting treatment was carried out to retain 1 or 2 leaves, so as to facilitate the absorption of water and the formation of photosynthesis. When dealing with the cut, the distance between the cut and the lower bud should be controlled at about 0.3cm, and it should be obliquely cut into a horseshoe shape to increase the contact surface between the cambium and soil to facilitate rooting.

5. Cuttings treatment

After the cuttings are cut and treated, they need to be tied up in the way of 50 cuttings in 1 bundle to ensure that the buds are facing up, place them neatly in the basin, and then soak the lower part of the cuttings in 1500 times solution of Guoguang brand for 2 hours.

6. Cutting

According to the row spacing of 5m × 10cm, the hole was drilled with a punch, and then the cuttings were cut, and the suitable depth was just passing through the sand layer.
