Fat sea has a mild diarrhea effect. Its mechanism is that the increase of intestinal contents after taking fat sea orally can produce mechanical stimulation, which results in the occurrence of diarrhea caused by the increase of reflex intestinal peristalsis. For anesthetized dogs, the intestinal peristalsis can be significantly increased by soaking fat sea overseas cortex, soft shell and kernels separately. This effect can be antagonized by atropine. Rabbit intestinal peristalsis in vitro was increased by the extract of benevolence, but the effect of outer skin and soft shell was not obvious.

A look at the nature of the soil. Low-lying lands and saline-alkali lands should use acidic fertilizers such as ammonium nitrate, ammonium sulfate, and superphosphate; alkaline soils such as urea and ammonium bicarbonate should be used for acidic soils; and volatile sulfuric acids should be used for sandy lands with poor water and fertility conservation capabilities. Fertilizers such as ammonium or urea. Second, look at the characteristics of fertilizer. Shallow application, application, or application with water should be avoided so as to avoid wastage of fertilizer efficiency and waste. Three see the need. Seedlings of 6 to 7 leaf lengths should be top-dressed with coarse fat to induce early rooting of the tiger root; chemical fertilizers should be applied at the jointing stage, accounting for 30% to 40% of the top-dressing amount; the amount of fertilizer at the booting stage should be increased to account for the total amount of fertilizer. The amount of 50% to 60%; the amount of nitrogen applied in the early stage, spraying the foliar fertilizer in the middle stage, spraying potassium dihydrogen phosphate at the seeding stage. Look for growth. Strong seedling plots can be fertilized; weak plots in addition to chemical fertilizers but also after the application of good decomposing good manure, cake fat; to strong seedlings in the plots of weak seedlings to eat rice, more fertilizer, so weak seedlings become strong. After fertilization, cover the soil with deep cultivator. Five to see the law of reproduction. In the seedling stage, fertilization is too early to facilitate the seedlings; the fertilization of the male and female ear can not be late, and the old seedlings can be prevented;
