Cassia seed is the seed of Cassia acuminata. Cassia bicuspidata got its name because pods often hang on the top of branches in groups of two. Its leaves are like Sophora japonica, and some people call it double pod Huanghuai. Pods look like cowpeas. In the south, people call it a weenie tree. Cassia acuminata has lush foliage, early fruiting, long flowering period and bright colors. And has the functions of dust prevention and smoke prevention. Planting double pods on both sides of the road or in the community will become a beautiful scenery in autumn.

Cassia is native to tropical America and cultivated in tropical areas all over the world. China, Guangdong, Guangxi and other provinces have introduced and cultivated them. Cassia acuminata has strong wind resistance, dust resistance and smoke resistance, and is especially suitable for growing in slightly acidic soil or latosol with medium fertility.

breeding technology

1. Seedling raising technology: sow seedlings, collect mature seeds, carefully apply base fertilizer, sow in stages, cover with a layer of fine sand of 0.5-0.8 cm after sowing, spray water, cover with sunshade net, strengthen fertilizer and water management, uncover sunshade net before seedlings leave the nursery, gradually reduce watering times and amount, stop fertilization, and promote lignification of seedlings, with a height of 70-80 cm.

Cutting and seedling raising: in spring, select the lateral branches of healthy mother trees, cut them into cuttings with the length of 10~ 12 cm, insert the cuttings into 2 parts of loam+1 part of burning soil+1 part of sand matrix, and insert them to a depth of 3~4 cm, and spray water 5~6 times a day.

2. Cultivation techniques: select slightly acidic or latosol with good drainage for soil preparation, dig 40×40× 30 cm planting holes according to the plant spacing of 40× 40 cm, apply base fertilizer in the holes before planting, and water after planting. When the seedling height is 1 m, the core should be picked and topdressing should be done 2 ~ 3 times before and after flowering to promote flower hypertrophy and prolong flowering period. Prune and prune in time to maintain a good plant shape.
