How to plant Senna leaves

Senna plays a very important role in our life, it is a main ingredient of laxative, it can be used to moisturize the intestines and defecate, and now there is a kind of tea called Senna on the market, it is a kind of health tea that can be used to lose weight, but all need to strictly control the proportion of Senna, otherwise it will cause gastrointestinal discomfort. So how to grow Senna leaves? Let's take a look at it next.

1. Land selection and preparation

Senna is more suitable for growing in a dry environment, so the topography of the planting land is generally on the high side, the drainage is relatively good, the soil permeability is strong, and the soil fertility is sufficient. We should reorganize the soil about a month before planting, so that it has enough time to sun up the soil, there can be no stagnant land in the field, and ditches are opened at an interval of about 1.5 meters in the field for drainage, and finally sprinkle the base fertilizer and wait for sowing.

2. Scientific sowing

The most commonly used planting method of Senna is seed direct seeding, which is more suitable for sowing in the hot and dry season, and can be planted in many places. Before sowing, we need to wet the soil before sowing, and then sow the seeds according to the row spacing of 70 centimeters. The distance between plants is 60 cm, and then cover the seeds with soil, and finally cover it with a layer of grass, so as to keep the land moist. Another planting method is seedling transplanting, which is similar to seed sowing. When it grows to about 10 to 15 centimeters after emergence, it can be transplanted according to a reasonable density.

3. Field management

Senna leaves do not need too much water in the growth process, but they also need to be watered, so we should strictly control watering, watering at the initial stage of Senna leaf growth, followed by watering in its peak growth period. in case of heavy rainfall, it is necessary to discharge the water from the field in time, otherwise it will affect its growth. In the process of its growth, it is generally necessary to apply multiple fertilizers, mainly nitrogen fertilizer, to promote the growth of Senna leaves, followed by the appropriate amount of phosphate fertilizer. When Senna leaves grow to a certain length, the buds and terminal buds should be removed in time, so that they can promote the growth of Senna leaves. Finally, we should pay attention to the irregular ploughing and weeding to maintain the permeability of the soil.

4. Pest control

Due to the special planting time of Senna leaves, the incidence of blight is very high during this period, so we should prepare for prevention in time, strengthen the management of the field, and then use Bordeaux solution to prevent it. After the onset of the disease can be treated with wettable zinc. At the same time, during this period will be accompanied by the emergence of pink butterfly larvae, we can combine trichlorfon control.
