生命素叶面肥在和平县猕猴桃上的应用试验

Application Testing of Biotin Foliar Fertilizer on Kiwifruit in Heping County

和平县是全国最南端猕猴桃栽培基地县,也是广东省唯一猕猴桃产区,且种植面积每年都在扩大,是和平县农业支柱产业之一。为了提高叶面肥在猕猴桃上的使用效率、促进植株生长发育,提高产量和品质,增加果农的经济效益,本文研究不同浓度生命素叶面肥在和平县猕猴桃上的应用效果,以3年生大果红阳和3年生武植三号猕猴桃为试材,分析喷施不同浓度生命素叶面肥,测定新梢长度粗度、叶绿素含量、果实内外观品质和经济效益等指标,发现叶面喷施生命素叶面肥400~800倍液均能有效促进新梢增粗、伸长生长,提高采果期叶片中叶绿素a、叶绿素b含量及叶绿素总量,并显著提高猕猴桃果实硬度、总糖、VC、可溶性固形物含量等,提高单果重、产量及经济效益。

Heping county is the southernmost kiwi cultivation base county in China. It is also the only kiwifruit producing area in Guangdong province, and its planting area is expanding every year. It is one of the pillar industries in Heping county. In order to improve the using efficiency of foliar fertilizer on kiwifruit, promote plant growth and development, increase the yield and quality of fruit, enhance famers＇ economic benefits, research on the application effect of different concentrations of biotin foliar fertilizer on Kiwifruit was carried out in Heping county of Guangdong province. Three-year- old ＂Hongyang＂ and ＂Wuzhi 3＂ were tested by applying different concentrations of biotin foliar fertilizer to measure quality of fruit, length and diameter of new shoot and economic benefits. It showed that 400？800 times of foliar fertilizer on leaves could significantly increase hardness, total sugar, VC and soluble solids of fruit, and effectively promote the shoot thickening and elongation, improve single fruit weight, production, quality and economic benefit.
