Effects of two soil conditioner combined application on the growth,yield,and quality of continuous cropped watermelon in facility
摘要
Abstract
In order to investigate the effects of two soil conditioners combined on the growth of continuous cropped watermelons in facility in the northwest region of Hebei province,a field experiment was conducted using the watermelon variety'qilin'as experimental material.Six treatments were set up,including conventional fertilization(CK),conventional fertilization+soil conditioner A 90 kg/hm2(T1),conventional fertilization+soil conditioner B 9.0 kg/hm2(T2),conventional fertilization+soil conditioner A 45 kg/hm2+soil conditioner B 4.5 kg/hm2(T3),conventional fertilization+soil conditioner A 60 kg/hm2+soil conditioner B 3.0 kg/hm2(T4),conventional fertilization+soil conditioner A 30 kg/hm2+soil conditioner B 6.0 kg/hm2(T5).The main vine length,stem diameter,maximum leaf length and width,net photosynthetic rate,and chlorophyll content at different growth stages,root growth indicators,yield and quality of watermelons at harvest stage were studied.The results showed that all soil conditioner treatments promoted the growth of watermelon leaf,main stem and stem diameter,in which T3 treatment had the best effects.During the pruning and flowering period,the chlorophyll content and net photosynthetic rate of each treatment reached their maximum values,and T3 treatment had the highest chlorophyll content and net photosynthetic rate,which increased by 14.71%and 13.45%,respectively,compared to CK.The root length,surface area,volume,fresh weight,and dry weight were all maximized in T3 treatment,which was significantly higher than CK,with increases of 26.51%,32.14%,45.87%,42.52%,and 35.00%,compared to CK,respectively.Compared to CK,the yield and net profit of T3 treatment were the highest,increasing by 23.72%and 48.98%,respectively.The soluble solids,soluble sugar,soluble protein and vitamin C content of T3 treatment had the highest levels,which were significantly higher than CK,increasing by 11.30%,28.62%,72.73%,and 40.77%,respectively.The titrable acid content of the T3 treatment was the lowest among all treatments,decreasing by 28.95%compared to CK,and was significantly lowered than CK.The thickness of the watermelon skin in T3 was significantly lower than that in CK,with a decrease of 14.51%.In conclusion,in the production of continuous cropped watermelon in facilities in the northwest region of Hebei province,T3 treatment could achieve the goal to promote watermelon growth,enhance photosynthesis,increase the yield and economic benefit,improve watermelon quality.Therefore,T3 treatment was a suitable soil conditioner application formula for continuous cropped watermelon in facilities in the northwest region of Hebei province.关键词
