配方施肥对核桃不同果期产量、果实性状与植株生长的影响

Effects of Formula Fertilizers on Production,Fruit Traits and Individual Growth of Walnut at Different Fruiting

施肥是核桃栽培中提高核桃产量和品质的最有效途径,探讨不同施肥配方对初果期和盛果期产量、果实形状和植株生长的影响,可为配置适宜的施肥配方,以及提高核桃产量提供科学依据。通过对初果期和盛果期的核桃样树,施加3个不同的复合施肥配方,然后对其果实产量、果实性状和植株生长指标等进行科学分析。结果表明:在初果期和盛果期,3个施肥配方在一定程度上对果实产量、果实性状和植株生长都起到增益作用,尤其以配方1增益效应最为显著。在研究区域内,对初果期和盛果期的核桃树均可采用配方1进行施肥管理,以达到持续、稳定获得核桃高产的目的。

Fertilization tends to be the best way to improve production and quality of walnut so that it is necessary to explore impacts of different formula fertilizers on production,fruit traits and growth at early fruiting period and full bearing period in order to provide scientific support for better fertilizer configuration and walnut production improvement.Three different formula fertilizers were exerted on walnut sample trees at early fruiting period and full bearing period respectively.Then fruit production,fruit traits,individual growth indexes,etc.had been analyzed scientifically.The results showed that all three formula fertilizers were able to facilitate production,fruit traits and growth to some extent at early fruiting period and full bearing period,among them the first formula functioning most significantly.Therefore,in the study area,the first fertilizer formula may be introduced in walnut in both periods to gain high production reliably and continuously.
