施钾量对设施甜瓜生长发育及产量品质的影响
Effect of Potassium Rate on Growth, Yield and Quality of Facilities Melon
摘要
Abstract
[Objective] This project aims to explore the effect of potassium rate on growth,yield and quality of Hami Melon and confirm the appropriate rate of potassium under the cultivated conditions of mulch drip irrigation in facilities.[Method] The cultivar of melon-Huangpi 9818 was taken as the experimental material,one-factor randomized block was designed,four treatments of potassium were applied to conduct the field plot experiment.[Result] The dry matter dynamic accumulation of different potassium treatments show the variation rule:slow accumulation-rapid accumulation-slow accumulation,and after the emergence during 61-85 d,the dry matter dynamic accumulation is at the exuberant stage,the dry matter accumulation of treatments is 67％-72％ in total accumulation.With the of process of growing period,the distributive proportion of dry matter accumulation in nutritive organs is reducing,he distributive proportion in reproductive organs is increasing.Treatment K2 gets the highest allocation of dry matter,165.7 g/plant at maturity stage,which is significantly different from K0 and K1.During the whole growth period,the stem diameters of treatments K2,K3 are both higher than those of treatments K0 and K1.[Conclusion] It's showed that increasing the rate of potassium can greatly promote the increment of yield and quality in a certain range,the highest yield of K2 is 31,970 kg/hm2.Soluble solid content,total sugar,vitamin C reach their maximum with the amount of 150 kg/hm2 of potassium.关键词
