    摘要:

    为了解不同施肥方案对红玉杧及土壤理化性质的影响,并为贵州红玉杧提质增效及改善土壤环境提供参考依据,以贵州种植5年的红玉杧为试材,共设计3个处理,处理1(CK)采用当地常规的施肥方法,处理2(T1)在常规施肥的基础上增施硫酸钾肥,处理3(T2)在常规的施肥基础上增施硫酸钾肥和海藻肥。分析不同施肥处理对果树茎粗、产量、果实品质、叶片和果实养分含量、土壤理化性质的影响。结果表明:T1、T2处理单株增产效果显著,较CK处理分别提高了15.61%、19.09%;主成分分析表明,T1、T2处理的综合得分明显高于CK处理,说明增施硫酸钾肥和海藻肥对果实品质改善效果明显。从叶片、果实、土壤养分分析结果来看,T1、T2处理叶片中钾、镁、铜、锌含量都能得到明显的改善,显著高于CK处理;钙含量CK处理显著高于T1、T2处理;果实中除氮元素外,CK处理的养分含量均高于T1、T2处理。T2处理土壤中的有机质比CK处理增加了106.73%,速效钾含量比CK处理提高了782.08%,但是T2处理的有效磷含量却比CK处理降低了92.78%。增施硫酸钾肥和海藻肥后,T1、T2处理总产值分别增加了15.55%、19.08%,VCR(施肥后增加农产品所得价值与施肥增加开支的比值)分别为12.12、5.53,从产投比而言是划算的,对提升红玉杧产量、品质及改良土壤理化性质效果显著,红玉杧管理上可以适当增施这两种肥料。

    Abstract:

    The effects of different fertilization treatments on the soil physical and chemical properties and Hongyu mango growth were studied to provide references for improving the quality of Hongyu mango and soil environment in Guizhou. The 5-year Hongyu mango was used as the test material.Three treatments were set up,including CK( the local conventional fertilization method),T1(potassium sulfate fertilizer applied on the basis of CK) and T2(potassium sulfate and seaweed fertilizer applied on the basis of CK).The effects of different fertilization treatments on stem diameter,yield,fruit quality,leaf and fruit nutrient content of fruit trees,and soil physical and chemical properties were analyzed. The results showed that:T1 and T2 treatments had significant effect on increasing yield per plant,which were 15.61% and 19.09% higher than CK treatment,respectively.Principal component analysis showed that the comprehensive scores of T1 and T2 treatments were significantly higher than CK treatment,which indicated that the effects of potassium sulfate fertilizer and seaweed fertilizer application on fruit quality were significant.From the results of leaf,fruit and soil nutrient analysis,the contents of potassium,magnesium,copper and zinc in leaves of T1 and T2 treatments were significantly improved,which were significantly higher than those of CK treatment; the calcium content of CK was significantly higher than that of T1 and T2 treatments; except nitrogen,the nutrient content of CK treatment was higher than that of T1 and T2 treatments.Compared with CK,the organic matter in T2 treatment increased by 106.73%,the available potassium content increased by 782.08%,but the available phosphorus content of T2 treatment was 92.78% lower than that of CK treatment.After applying potassium sulfate and seaweed fertilizer,the total output value of T1 and T2 treatments increased by 15.55% and 19.08%,respectively,VCR (the ratio of the increase in the value of agricultural products after fertilization to the increased expenditure on fertilization) were 12.12 and 5.53,respectively,which was also cost-effective in terms of ratio of production to input,which had significant effects on improving yield,quality and soil physical and chemical properties of Hongyu mango.These two kinds of fertilizers could be appropriately applied in the management of Hongyu mango.
