According to relevant introductions, I planted 50 to 60 square meters indoors, and last year's harvest was good. This year I began to expand the planting, or to follow the method of last year. In September this year, I started digging and sold it on the market for only three days. Then I dug again, only to find that all the Gastrodia elata was rotten. How is this going on? Zhang Qiudong, Department of Disease and Pest Control of Provincial Plant Control Station, answered: most of the causes are due to bad environment, such as high temperature, high humidity, poor ventilation and so on.

Zhang Qiudong, Department of Disease and Pest Control of Provincial Plant Prevention Station, answered: most of the causes are due to bad environment, such as high temperature, high humidity, poor ventilation and other factors that are not conducive to the growth of Gastrodia elata, resulting in the yellowing of the tuber skin of Gastrodia elata, the decay of the central tissue, and the internal slurry shape. Finally died of rot and smelly empty shell.

Prevention and control methods: first of all, strictly select Gastrodia elata species. It is best to choose the zero generation or the first generation of hybrid Gastrodia elata. If you find that the hemp body is not full, the growth point is not obvious, and there are signs of decay (even a small spot), you should discard it. The second is to pay attention to indoor cleanliness and hygiene, do a good job in environmental hygiene, and often be ventilated and ventilated.

Attention should also be paid to pest control. Common pests are mole cricket, grubs and termites. Prevention and control methods: first, manual hunting. Once the uplift of topsoil or sand in the cultivation site is found, the soil or sand can be removed and killed manually. The second is light trap. With the help of the phototaxis of most insects, a black light is set up in the cultivation site of Gastrodia elata to trap and kill adults. The third is drug entrapment. Mirex or anti-pest powder can be sprinkled on the cultivation site.
