So how should Psoralea corylifolia be planted? Below, the editor brings you the cultivation techniques for Psoralea corylifolia. Let's take a look!
1. Site selection and land preparation
Psoralea corylifolia likes to grow in dry places with sufficient light, so when choosing a planting site, it is necessary to ensure a place with sufficient light, dry terrain, and good drainage and irrigation for planting. After choosing the land, do a good job of land preparation, reduce deep plowing and turning, with a depth of about 30 cm. After leveling and fine plowing, make beds and open furrows to prepare for planting. Pay attention to controlling the specifications such as the length, width, and height of the beds, and it is best to shape the furrow surface into a turtle-back shape, which is not only beneficial to the growth of Psoralea corylifolia, but also beneficial to its planting management.
2. Seed soaking and seedling raising
Before sowing, soak the seeds in a solution such as gibberellin for about 14 hours, which can effectively reduce the phenomenon of flower and fruit drop in Psoralea corylifolia, improve the fruit-setting and seed-setting rate, and increase yield. Then soak the seeds in cold water for about 2-3 days so that the seeds fully absorb water, then remove them and air-dry them. Then sow around Qingming Festival, mainly by drilling, with row spacing controlled at about 45 cm, and cover with about 4 cm of soil after sowing. Then water thoroughly and cover with soil and film to improve the soil's moisture retention capacity. Under normal management, seedlings can emerge in about a week.
3. Timely transplanting
After sowing, do a good job of sowing management. Before seedlings emerge, keep the soil moist. After the seedlings grow, carry out thinning around May, with plant spacing of about 18 cm and no more than 2 seedlings retained per spot. When thinning, pay attention to the principle of keeping the strong and removing the weak to ensure uniform and complete seedlings. As just mentioned, after sowing, under normal management, seedlings will emerge in about a week. Then strengthen seedling management, and after about 1 month, transplanting can be carried out. When transplanting, control the planting spacing between plants and rows well to prevent overly dense planting, mutual shading in the middle and later stages, and impact on growth.
4. Field management
After the seedlings survive transplanting, pay attention to doing a good job of cultivating and weeding, keeping the soil sufficiently loose, with normal drainage and irrigation capacity and no weeds. Especially after heavy rain, otherwise water accumulation may cause root rot of Psoralea corylifolia seedlings and lead to pests and diseases. However, also pay attention to keeping the soil moist. During the planting process, fertilizer must be applied more than twice, mainly with decomposed farmyard manure, to meet the nutrients needed for the growth of Psoralea corylifolia. Finally, do a good job of pest and disease control to avoid unnecessary losses to Psoralea corylifolia and enhance its growth.
The above is a brief introduction to the cultivation techniques of Psoralea corylifolia. Psoralea corylifolia has relatively strong growth ability and is relatively simple to plant, but everyone needs to do a good job in planting management to ensure the growth of Psoralea corylifolia and increase yield. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
