容器对基质栽培春茬黄瓜生长和产量的影响
|
摘要
以黄瓜品种博美626为试验材料,采用有盖苯板泡沫栽培箱、无盖苯板泡沫栽培箱、无盖塑料栽培槽、塑料栽培袋4种不同容器对其生长、根系活力、容器内根际环境、产量进行比较研究,旨在筛选出适合宁夏黄瓜高产基质栽培的栽培容器。使用塑料栽培袋栽培的黄瓜在生长中后期的株高、茎粗高于其他3个处理,且黄瓜根表面积、平均直径和单株根体积也显著高于其他各处理。塑料栽培袋栽培的黄瓜地上部鲜质量、地上部干质量和地下部干质量显著高于其他各处理,根系活力最大。塑料栽培袋的基质湿度最大,变化较为稳定,且在春季栽培中有明显根际温度优势。塑料栽培袋处理的黄瓜总产量、单株平均产量都极显著高于其他3个处理。说明塑料栽培袋是黄瓜春季栽培中适宜的栽培容器。
Comparative studies were carried out on the growth,root vigor,rhizosphere temperature and humidity,and yield of cucumber variety Bomei 626 planted in four containers,lid-free benzene plate foam boxes,lidded benzene plate foam boxes,lid-free plastic cultivation slots,and plastic bags,to select a kind of container for high-yielding substrate cultivation. The cucumber planted in the plastic bags showed higher plant and wider stem diameter in the middle and late growth stages,and the root surface area,root diameter and root volume were bigger. The substrate in plastic bags exhibited the highest and stable humidity,and optimal rhizosphere temperature for spring cucumber. The fresh weight and dry weight of aerial part,the dry weight of underground part,and the root vigor of Bomei 626 were higher than those in other three containers. As a result,Bomei 626 planted in the plastic bags achieved the highest yield. Plastic bag is the kind of container favorable for spring cucumber.
