Matters needing attention in planting Cassia seed

The main medicinal part of Mingzi is its mature and dry seeds. It has the functions of reducing fat, eyesight, moistening intestines, defecation and so on. It is often used to make tea and drink in our lives. At present, the main producing areas of cassia seed in China are Anhui, Guangzhou, Sichuan, Zhejiang and Guangzhou. So do you know what problems you need to pay attention to when planting cassia seeds? Let's take a look at it together.

1. Seed treatment

The seed of cassia seed is very dry after harvest and preservation, and its seed epidermis is relatively hard. Well, in order to improve the emergence rate of cassia seeds, we need to soak the seeds of cassia seeds in warm water with a temperature of about 40 to 50 degrees for one day, wait for the seeds to fully absorb moisture, and then remove the seeds after drying them. Soak them in chlorothalonil solvent for 15 minutes, rinse them with clean water and dry them before sowing.

2. Sowing seeds

When sowing, we must pay attention to the depth of sowing, not too deep, not too shallow, otherwise it will affect the budding rate of cassia seed. Sowing is usually done by strip sowing, so the depth of each ditch is about five centimeters. Sow the seeds evenly, cover them with soil, and then water each ditch once. At this time, we should pay attention to that the watering should not be too much, a little watering is enough, otherwise the seeds of Cassia seed are easy to be soaked.

3. Density

Cassia seed planting is also particular about density. We should determine the planting density of Cassia seed according to its growth habits, fertile degree of planting land, topography and other conditions. In general, the row spacing of cassia seed is about 55 to 60 centimeters, while the plant spacing is about 25 to 30 centimeters. In this way, the permeability of the planting land is good, and it can not only make full use of land resources, but also facilitate the field operation in the later stage.

4. Pick leaves and hit the top

When the seedlings of Cassia seed grow to about 30 to 40 centimeters, we have to top and pick the heart, which can promote the growth of branches, thus increasing the yield of Cassia seed. There is the proper removal of branches and leaves, for example, the leaves at the bottom of cassia seeds can generally be removed, which can not only reduce nutrient absorption, but also improve field permeability.

5. Cultivate the soil

When planting cassia seeds, we also need to pay attention to the timely cultivation of soil. The soil cultivation of Cassia seed needs to be carried out in two stages, the first stage is before Cassia seed enters the flowering stage, which is to enhance the air permeability of the soil; the second stage is after Cassia seed pods, we should carry out ligands in time, which can prevent lodging, enhance the saturation of Cassia seed, and achieve the goal of high yield.

The above points are easy to ignore in the process of planting, but they have a great impact on the yield and quality of Cassia seed. Then everyone must pay attention to these problems in the future planting. Of course, we also need to pay attention to the supply of water, the supplement of nutrients and the prevention and control of diseases and insect pests.
