Effects Of Different Fertilization Treatments On The Growth And Yield Of Jujube

Jujube is widely grown in northern Shaanxi and is an important industry for farmers to increase their income.In this study,the commonly used Goutouzao,Muzao and Junzao in northern Shaanxi were tested,Fertilize the date trees with organic fertilizer,compound fertilizer,special fertilizer and fungus fertilizer.There are three levels of fertilization,two fertilization and three fertilization.Taking the indexes of growth and development,quality of fruit setting and yield of three jujube trees as the research content,the investigation of statistical data and correlation analysis were conducted to explore a suitable fertilization scheme for jujube trees.This will provide a theoretical basis for increasing the economic benefits of jujube cultivation and reducing the cost of fertilization for the region.The main results of this experiment are as follows:1.Effects of Different Fertilization Treatments on the Growth and Yield of Goutouzao.Organic fertilizer has a significant effect on the growth and fruit size of jujube,The number of flowering and the number of fruit set have increased significantly.The increase in leaf area also promotes the growth of jujube trees.Three kinds of different fertilization times have greatly improved the output of jujube trees,and the yield increased by 27.67%,27.76% and 26.31% respectively.Under the two times of fertilization,the single fruit weight increased significantly and increased by 33.22%.Compound fertilizer had no significant effect on the index of jujube tree.The jujube special fertilizer will increase the jujube flowering and increase the size of the jujube fruit,but the fruit set is generally low,the increase of fruit weight is not obvious,and there is no increase in production.After fertilizing fertilizer,there was a certain increase in the number of fruit set and fruit weight,and the yield also increased,but the fruit size did not change significantly.Considering the fertilizer effect of jujube planting,it is recommended to use organic fertilizer to fertilize jujube trees twice a year.2.Effects of Different Fertilization Treatments on the Growth and Yield of Muzao.The use of organic fertilizer and compound fertilizer has a very good effect on fertilizing jujube trees,Three different times of fertilization have a good effect of increasing yield.The output increased by 27.88% and 23.75% respectively.The use of organic manure fertilization only once a year has significant effects on jujube growth and fruit quality.Compound fertilizer had no significant effect on fruit set number and fruit setting rate.Special fertilizers and fungus fertilizers have a single effect on the various indicators of the jujube tree and are not recommended for fertilization.Therefore it is recommended to use organic fertilizer fertilized only once a year.3.Effects of Different Fertilization Treatments on the Growth and Yield of Junzao.Organic fertilizer has significant fertility effects on growth indicators and yields of jujube trees.Increased production by 37.50%,Twice fertilization on fruit Vertical length and Horizontal length Significantly increased,Increased by 12.89% and 16.72%;Fungus fertilizer had a greater impact on flowering and fruit setting in early jujube trees.Compound fertilizer and red dates had a good effect on the quality of fruit set in the later period,but the fertilizer effect was relatively single and was not recommended for fertilization.Comprehensive consideration of jujube tree overall fertilization effect and economic benefits recommend the use of organic fertilizer,fertilization in the whole year in twice.The use of organic fertilizer has better effect on the growth and yield of Goutouzao,Junzao and Muzao,The effect is stable and long-lasting.The effect of compound fertilizer is related to jujube tree varieties.Special fertilizers have a more prominent effect on fruit size and weight gain.Fungus fertilizer has obvious effects in the growth and development of jujube trees.The compound fertilizer special fertilizers and fungus fertilizer is easily affected by the number of fertilization.
