不同栽培规格对粉马蹄产量影响比较试验

Comparative Experiment on Yield of Powdered Water Chestnut with Different Cultivation Specifications

[目的]优化粉马蹄种植技术,提高单产水平。[方法]对"桂粉蹄1号"新品种进行四种不同栽培规格,采用随机排列,三次重复共12个小区试验,分析不同栽培规格对产量及淀粉含量的影响。[结果]试验结果表明,"桂粉蹄1号"新品种栽培规格在60cm×60cm到90cm×90cm之间,产量和淀粉含量均随着栽培密度的减小而逐步增加且在70cm×70cm处达到最大值,超过70cm×70cm之后均逐步下降。[结论]建议在钟山县地域范围内,适当增加粉马蹄的种植密度,采用70cm×70cm的栽培规格,能够提早封行,积累淀粉含量,进一步提高粉马蹄的品质、产量和经济效益。

[Objective]To optimize the planting technology of powdered water chestnut and improve the yield per unit area.[Method]Four different cultivation specifications of"Guifenti No.1"new Variety were used to analyze the effects of different cultivation specifications on yield and starch content in 12 plots by random arrangement and three times of repeated experiment.[Result]The results showed that when the cultivation size was 60 cm×60 cm to 90 cm×90 cm,the yield and starch content of Guifenti No.1"increased gradually with the decrease of cultivation density,and reached the maximum value at70 cm×70 cm,but decreased gradually after 70 cm×70 cm.[Conclusion]It is suggested that the planting density of powdered water chestnut should be increased appropriately in the area of Zhongshan County,and the cultivation specification of 70 cm×70 cm can be adopted to seal the row in advance,accumulate starch content,and further improve the quality,yield and economic benefit of powdered water chestnut.
