喷施生物微肥对冬小麦生长发育及产量的影响

Effect of Spraying Biological Micro-fertilizer on Growth and Development and Yield of Winter Wheat

为探讨喷施生物微肥对小麦植株生长和产量的调控效应,以半冬性小麦品种郑麦379为供试材料,研究喷施生物微肥赛土丰(STF)、赛苗旺(SMW)对冬小麦生长发育及产量的影响。结果表明,与清水对照相比,STF处理和STF+SMW处理可显著促进冬小麦株高、次生根的生长,SMW处理和STF+SMW处理叶色较深,STF、SMW、STF+SMW处理均可有效防御病虫害。STF+SMW处理和SMW处理的穗粒数分别较对照显著提高12. 55%和12. 28%; STF+SMW处理和STF处理的千粒质量分别较对照显著提高13. 41%和12. 76%; STF、SMW、STF+SMW处理均可显著提高冬小麦产量,分别较对照提高4. 65%、6. 31%、18. 60%,且STF+SMW处理显著高于STF、SMW处理。说明在中后期叶面喷施赛苗旺对冬小麦穗粒数有积极的促进作用,种植前土壤喷施赛土丰可以提高冬小麦千粒质量,两者结合施用可以通过提高冬小麦穗粒数和千粒质量来提高产量,且效果显著。

In order to study the regulation effect of spraying biological micro-fertilizer on plant growth and yield,the effect of spraying biological micro-fertilizer Saitufeng(STF),Saimiaowang(SMW)on winter wheat growth and yield was studied with Zhengmai 379 as material.The results showed that compared with water control,STF treatment and STF+SMW treatment could promote the development of plant height and secondary root;the leaves color of SMW treatment and STF+SMW treatment was deeper;STF treatment,SMW treatment and STF+SMW treatment played an active role in protecting wheat plants from diseases and insect pests.Compared with control,the grain number of STF+SMW treatment and SMW treatment significantly increased by 12.55%and 12.28%,respectively;the 1 000-kernel weight of STF+SMW treatment and STF treatment significantly increased by 13.41%and 12.76%,respectively;the yield of STF treatment,SMW treatment and STF+SMW treatment significantly increased by 4.65%,6.31%and 18.60%,respectively,the yield of STF+SMW treatment was significantly higher than those of STF treatment,SMW treatment.Overall,spraying SMW could promote the increase of grain number of winter wheat,spraying STF could promote the increase of 1 000-kernel weight of winter wheat,spraying STF and SMW could improve the yield by increasing both the 1 000-kernel weight and grain number,and the effect was very significant.
