Effects of Equal-nitrogen Substitution of Chemical Fertilizer with Different Green Manures on Yield and Quality of Zucchini
摘要
Abstract
To investigate the effects of equal-nitrogen substitution of chemical fertilizers with two green manure crops,namely Vicia villosa and Raphanus sativus,on the yield,quality,and fruit morphology of zucchini,a control group(CK)with full application of chemical fertilizers was set up,along with 10 treatments(VM1-5 and RM1-5)based on different substitution rates of green manures.The results showed that compared with R.sativus,the substitution of chemical fertilizers with V.villosa had a better promoting effect on zucchini growth.When the substitution rate of V.villosa reached 40%(VM4 treatment,60%chemical fertilizer+40%V.villosa),the yield of zucchini was the highest,increasing by 13.38%compared with CK;the fruit length and diameter also increased significantly,by 5.55%and 11.53%respectively compared with CK.Meanwhile,after equal-nitrogen substitution of chemical fertilizers with V.villosa,the chlorophyll content in zucchini leaves during the budding stage increased,and the nutritional composition of zucchini fruits was also affected.The crude fiber content decreased,and the potassium content increased significantly.Among them,the VM4 treatment had the highest potassium content and VC content.In addition,equal-nitrogen substitution of chemical fertilizers with both V.villosa and R.sativus helped reduce the nitrate content in zucchini fruits.Among all treatments,the VM4 treatment had the lowest nitrate content,which was 19.77%lower than that of CK,with a significant difference.In conclusion,the combined application scheme of 60%chemical fertilizer+40%V.villosa had the best effect on improving the yield and quality of zucchini.This study provides a new scheme for reducing chemical fertilizer application in zucchini cultivation in Yunnan,and is of certain significance for realizing the sustainable development of regional agriculture.关键词
