不同覆盖模式对阳荷笋的影响研究

Study on the Effect of Different Coverage Modes on the Growth of Shoots of Zingiber striolatum Diels

为研究不同覆盖模式对阳荷出笋情况的影响,以鄂西北山区阳荷块茎为种源,采用黑膜、黑桶、秸秆3种覆盖模式进行对比试验研究。结果表明:黑膜和黑桶覆盖模式种植下,阳荷种姜的发芽率均达到90%以上。黑膜覆盖模式下种植效果最好,阳荷笋的平均长度、单笋质量及产量分别为15.81±2.02 cm、17.73±1.00 g、2622.45±100.05 kg·hm^(-2),并且阳荷笋外相较好,出笋时间最早。秸秆覆盖模式种植阳荷笋的成本虽然最低,但出笋质量较差,主要表现在对阳荷笋直立生长存在影响。在实际操作中,黑膜覆盖种植模式操作简单便捷,方便定期通风和数据统计分析。综合分析,黑膜覆盖是阳荷出笋生长较适宜的种植模式。

In order to study the effect of different mulching modes on the shoots of Yanghe,using the tubers of Yanghe as the material,three mulching modes of black film,black bucket and straw were used to conduct comparative experiments.The results showed that under the black film and black barrel mulching modes,the germination rate of Yanghe ginger was over 90%.The planting effect was the best under the black film mulching mode.The average length,single bamboo shoot weight and yield of Yanghe bamboo shoots were 15.81±2.02 cm,17.73±1.00 g,and 2622.45±100.05 kg·ha^(-1),respectively.The appearance of Yanghe bamboo shoots was good,and the bamboo shoots grown earliest time.Although the cost of planting Sunflower bamboo shoots with straw mulching mode was the lowest,the quality of shoots was poor,which mainly affected the erect growth of Sunflower shoots.In actual operation,the black film mulching planting mode was simple and convenient to operate,which was convenient for regular ventilation and statistical analysis of data.Comprehensive analysis,black film mulching is a more suitable planting mode for the growth of shoots of the sun lotus.
