Fertilization Technology Of Juglans Regia In Large Scale Production In Wushi County

Juglans regia'Wen185'and Juglans regia'Xinxin2'common walnuts are the main cultivation walnut major producing area of Wushi County,South Xinjiang basin.Due to lacking of the scientific fertilization technology for a long time,resulting in low overall yield,poor quality and low commodity rate,and this affects the economic benefit seriously of walnut producing areas in southern Xinjiang.Therefore,this study relies on"arid zone oasis fruits and grains and cotton intercropping for the key technology research and development"research results(scientific fertilization part),and carried out fertilization technology popularization in 80 hm~2 walnut production of Wushi County,Use control group CK,flowering fertilizer group(plant source nutrient solution)T1,fertilization(fertilizer)before bud and fruit enlargement period+flowering spray fertilizer(group)compound fertilizer solution T2 three different fertilization way,through measuring and analyzing the response of yield,quality and commodity rateof walnut,and did the verification of fertilization technology popularization of walnut production.The main results were as follows:(1)Through the analysis of walnut yield,the results showed that the two kinds of fertilization treatment about fertilizer in flowering stageT1 and fertilization+fertilizer in flowering stage T2 have improved the number and fruit weight of single fruit significantly of Juglans regia'Wen185'and Juglans regia'Xinxin2'common walnuts,also improved the production obviously.Between the two kinds,the T2 has better effect,and the production of yield per acre could get 229.68 kg and 214.34 kg,and higher than 31.7%and 35.8%respectively than the control group(CK).(2)The analysis of walnut quality showed that through the treatment of T2 had a significant effects which compared with CK(P<0.05)on the improvement of Juglans regia'Wen185'and Juglans regia'Xinxin2'common walnut quality indexes(kernel rate,hard shell thickness,fat content and protein content),while the treatment of T1 could improve the fat content significantly,but for the kernel rate,hard shell thickness and protein content had no obvious effect.(3)Through the analysis of the commodity rate of walnut showed that the two fertilization treatments had sensitive effects(P<0.05)on the increase of diameter,longitudinal diameter,lateral diameter and average diameter of Juglans regia'Xinxin2'common walnut,but on the fruit shape index increased insensitive of two Walnut varieties.The two Walnut varieties had the characteristics of large head,good shape,excellent quality,and the damage rate,empty shell rate and dark spot rate were low,and it also had a high commodity rate.
