稻田生态系的生境结构和小气候比较简单,而且只有相对较少的资源,因为,稻田生态系中的物种多样性越少,空余生境生态位就越多,这就导致稻田生态系统极不稳定,病虫害发生频繁,产量品质易被影响。1.选用抗病品种。结合当地天气、病虫害发生情况,选择适宜抗病品种。2.打捞菌核。根据病害后期形成的菌核会掉落在稻田里成为下一年的病原这一特点,在耕沤田时,
The habitat structure and microclimate of paddy field ecosystem are relatively simple and have relatively few resources because the less species diversity in paddy ecosystem and the more niche in free-range habitat, which leads to extremely unstable paddy ecosystem, Pests and diseases occur frequently, yield quality is easily affected. 1. Use resistant varieties. With the local weather, pests and diseases, choose suitable disease-resistant varieties. 2 salvage sclerotia. According to the late stage of the disease, the sclerotia will fall into the rice field to become the next year’s pathogen of this feature, farming plow field,
