Yanshan hongbingli processing factory takes you to know: what problems should be paid attention to when planting chestnut seedlings

Next, Yanshan red food chestnut manufacturer will discuss this problem with you to see what aspects should be paid attention to when planting. Here are the following points to know when planting chestnut seedlings:

1. Requirements of chestnut on environmental conditions: chestnut is one of the forest resources with early economic development in China. It likes light. The soil pH value is between 4.5-7.5, the annual average temperature is above 10 degrees, the average temperature during the growth period is 16-20 degrees, and the average temperature in winter can be planted within minus 25 degrees. Chestnut has strong adaptability, wide distribution, simple cultivation process and high yield. It can be cultivated economically in mountainous areas and beaches.

2. Variety selection: 9 kinds, such as maroon, chestnut, eosin, etc.

3. Cultivate strong seedlings: seed treatment: chestnut seeds are afraid of drying, heat and freezing. After seed selection, fumigate with aluminum phosphide, disinfect with 100 times methylthiophanate solution, treat seeds, and use clean and moist river sand. Sowing in department stores: from early March to early April, sow with a row spacing of 1 foot and a plant spacing of 5 or 6 inches. It is required that the stem of the seedling in that year should be greater than 0.8 cm, the height of the seedling should be greater than 1 meter, the root system should be developed, and 10000 plants should be planted per mu. Timely grafting: chestnut branches contain a lot of chemicals, and grafting cannot guarantee survival. Therefore, we must choose a good period and pay attention to grafting technology to improve the survival rate of enterprises. Autumn, August and October are suitable for budding. In spring, 20 days before germination, the SAP can be split and cut before it is fully utilized and recycled. When subcutaneous grafting is used, the new leaves should be expanded, and the sap flow problem should be fully developed. The rootstock can be effectively grafted about 20 days after germination. Scions should be collected as soon as possible before germination and stored in a cool place with sand at low temperature.
