Fertilizer application

During the flower bud stage and fruit period of Hippophae rhamnoides, Zhuangguotiling should be sprayed in time to increase nutrients, prevent falling flowers, increase fruit setting rate, accelerate its expansion and ensure high quality and high yield of fruit.

Soil

Hippophae rhamnoides has strong adaptability to soil. It is suitable to choose gravel soil and sandy soil with good permeability, but avoid too clayey soil.

Note:

Trim the tree shape

When Hippophae rhamnoides grows to a height of about 2-2.5 meters, it needs to be clipped. If you do not fight horizontally, the old should be kept new, the secret places should be trimmed, the branches should be left empty, the canopy should be trimmed well, and the crown will have a high yield.

Chemical control can be carried out in late April. 40% carbendazim glue suspension 500 times or methyl topiramate 800 times can be irrigated once a month for 3-5 times in a row.

The harm of aphids can be prevented by spraying 2500-3000 times of imidacloprid. For the harm of apple leaf moth and spring inchworm, it can be sprayed with 3000-fold solution, or 2500-fold solution can be used to control.

Second, what is the effect and function?

1. The role of soil and water conservation

Seabuckthorn has this role of many plants, seabuckthorn itself has a strong ability to resist drought, coupled with strong growth, adaptability is also relatively good in the wind and sand resistance, so, seabuckthorn is often planted in the desert, can play a good role in soil and water conservation and desert greening. In fact, in addition to the desert, in the barren western region, some seabuckthorn will also be planted to conserve soil and water. in addition, sometimes, in the process of urban greening, seabuckthorn will be used as the preferred plant.

2. Nutritional function.
