Planting techniques of Cassia seed

The planting technology of cassia seed needs to be determined according to its growth habits, which will be analyzed in detail below.

Growth habits: cassia seed likes warm and humid climate, not cold, and is afraid of frost, but it has lax requirements on soil, sand and clay can be planted, slightly alkaline soil grows best, and the root system is developed in well-drained, loose and fertile soil. Nitrogen-fixing rhizobium is the most, like phosphate and potassium fertilizer, and is more resistant to drought.

Propagation and cultivation: seed reproduction method, which can be divided into spring sowing and summer sowing, spring sowing before and after Qingming Festival, summer sowing before the Summer Solstice, applying fertilizer in the field before sowing, sowing or sowing at a distance of 30 cm between rows, opening a shallow ditch of 2m and 3cm, keeping the humidity suitable, seedlings can emerge in seven days. When the seedling height is 6 cm, it can loosen the soil and weed the seedlings, the distance between plants is 25 ~ 30 cm, check the seedling gap, transfer the seedling height above 40 cm, keep up with water and fertilizer, promote more branches, more flowering, more pods, beware of lodging, it is best to cultivate some soil at the root, hit the bottom leaves, to facilitate ventilation and light, enhance grain saturation, and achieve the purpose of high and stable yield.

Pest control: there are few diseases in Cassia chinensis, and the stagnant water is easy to cause root decay and affect the yield. Insect pests include aphids, spiders, cabbage insects, etc., which can be controlled by foliar spraying of trichlorfon, dimethoate and pyrethroid pesticides.

Harvesting and processing: generally in autumn September, when the pod changes from green to yellow, the field should beware of people and animals entering the field, colliding the pods to blow up the seeds. After Frosts Descent, when the dew is not dry on a sunny morning, cut off the whole plant, put it in the hospital for threshing, dry and clean, remove all kinds of impurities, pods, and so on.
