Cultivation Techniques and Management Key Points for Catechu
Catechu is a very traditional Chinese medicinal herb in China, mainly distributed in Yunnan Province, China. Its main medicinal part is the branches and trunk, and it has various functions such as stopping bleeding and promoting tissue regeneration, and clearing the lungs and resolving phlegm. It is mainly used for bruises and injuries, eczema and damp sores, etc., and its medicinal value is very high. Now catechu trees also have a certain planting area in China, so how exactly should catechu be planted? Below, the editor brings you the cultivation techniques for catechu, let's take a look together!
1. Timely seed collection
The main planting method for catechu is mainly seed propagation, so we must collect seeds in time before planting. When the color of the catechu fruit gradually darkens, it means it is ripe, and the fruit should be harvested in time before it falls off. Then put the fruit in the sun to dry for about 4 days to evaporate the moisture in the fruit, and open it after the fruit cracks. Carry out seed collection, selecting healthy seeds that are plump and have no wounds, to ensure the quality of the seeds. A high-quality seed can maintain its germination capacity for about one year, but it is easily harmed by pests, so it is best to sow immediately after harvesting, and its germination rate can reach about 85%.
2. Sowing and seedling raising
Although the germination ability of catechu seeds is relatively strong, in order to further improve the seed germination rate, we still need to do a good job of pre-sprouting before sowing. This can effectively improve the seed germination rate and ensure uniform seedlings. First, soak the seeds in water at a temperature of about 50 degrees, let it cool naturally, and then leave it in the water for about one day. After soaking, the germination time of the seeds can be shortened to about 4 days, but the root system of catechu is distributed relatively deeply, and the growth ability of the lateral roots is not strong. Therefore, seedlings should be raised first. When sowing in spring, after about one month of seedling raising, they can be transplanted and planted.
3. Planting and afforestation
Before planting, choose sandy soil with good drainage and irrigation and fertile soil for planting. If the plot is hollow and accumulates water, then drainage ditches should be set up to avoid severe water accumulation causing the roots of catechu to rot and affecting its normal growth. And do a good job of land preparation to improve soil looseness and promote the growth of young trees. Then control the spacing between plants and rows, dig the planting holes well, and apply sufficient decomposed farmyard manure as base fertilizer in each planting hole. Then transplant at the right time, do a good job of management after successful planting, and carry out afforestation.
4. Field management
After planting, water thoroughly to settle the roots, but the amount of water should not be too much, to avoid affecting the normal growth of catechu. Pay attention to observing the permeability of the soil, and avoid it being too closed off, which may lead to afforestation failure. And according to the actual growth of catechu and the fertility of the soil, topdress in time. Pay attention to doing a good job of intertillage and weeding, with each occurrence no less than two times, and appropriately cover with grass to improve the soil's ability to retain fertilizer and water. Finally, crops such as peanuts can be intercropped to improve the utilization rate of the soil and reduce the waste of land resources.
The above is a brief introduction to the cultivation techniques of catechu. During the planting process, pest and disease control should also be done well. Avoid pests and diseases harming the growth of catechu and causing a reduction in the economic benefits of planting. That is all for today's introduction.
