Preliminary study on anti-stress effect of fertilization under weak light and low temperature stress
The resistance to low temperature and weak light of microbial fertilizer and nitrogen fertilizer reduction in incubators are studied by taking maize as the test crop,and the anti-stress effects are compared with organic carbon nutrition(α-ketoglutaric),which has weak light resistance effect.The results show that under 66%light conditions,compared to conventional nitrogen treatment,the yields of microbial fertilizer treatment,nitrogen fertilizer reduction treatment and organic carbon nutrition treatment are all increased with an increase rate of 27%to 33%,both nitrogen fertilizer reduction treatment and microbial fertilizer treatment have a yield increase in resistance to weak light stress;The low temperature resistance effect of microbial fertilizer treatment is significantly better than that of nitrogen fertilizer reduction treatment,nitrogen fertilizer reduction treatment is slightly better than nitrogen increase treatment.Compared with conventional nitrogen treatment,microbial fertilizer treatment increases yield by 50%.
