1, pest control: ⑴ main ring rot disease is, in the incidence of spraying Bordeaux mixture 1:1:200, serious lime sulfur spray 0.3 Baume for prevention and treatment. ⑵ aphids more serious harm in the seedling stage, 40% of available times or dimethoate 2000 1:10 tobacco, lime for prevention and treatment. ⑶ morning liming can prevent slugs.
2, Harvest: bottle sprayer year 10 months late, Cassia fruit ripening. When the pods from green to brown, use sickle cut off from the base of the plants, placed drying yard threshing season, cleanse impurities, select full, no worm for the species.

Height 3-6 cm Time seedlings, the seedlings Ruomiao or too dense pull; height 10-13 cm, combined tillage weed, plant spacing of 30 cm by singling. In case of drought, proper watering.
4, fertilization: Cassia roots, rhizobia, nitrogen fixation can play without a lot of fertilization. ⑴ height 10 cm when applied per acre thin human waste 1,000 kg to promote seedling growth. ⑵ 6 mid Zaishi human waste 1000 kg.
