The Zunyi Pepper Standardized Planting Of Key Technologies And Evaluation

Hot pepper is one of important vegetable crops,and its planting area is increasing.Hot pepper industry occupies an important position in Zunyi agriculture. Hot pepper planting technique is so laggard that hot pepper yield and quality are low in this region,which greatly influences the income of hot pepper industry.Therefore, based on the current situation,key planting technique of hot pepper is researched and summarized in the thesis.The results are as follows.Producing conditions of Zunyi hot pepper are good,its market is wide,and it has become an supporting industry of city of Zunyi.However,there are so many problems with it at present.Varieties are not pure,planting technique is low,plant diseases and pests are serious,the layout of planting region is not rational,the related market facilities are slow,deep process gets behind,etc.So,some developmental methods, such as unambiguous target,increasing investment,better lead and service,are put forward.Hot pepper seed germination and seedling growth were affected when its seeds were treated with different methods.The effect of 55℃water soaking was best,and CuSO₄ or KNO₃ could be added to the 55℃warm water in practical production. Among three nursing seedling modes,floating nursing seedlings was the best.The indexes such as seedling height,stem diameter,dry and fresh weight,the index of strong seedling and so on were larger than those of other cultivating modes.Hot pepper yield was highest when the plants were spaced 0.25 m apart in 0.55 m rows,which was 10.67 kg more than that of the control.There was no difference for plant diseases and pests compared to the control.When 80 kg hot pepper special fertilizer was used per 667 m²,hot pepper yield reached 141.67 kg/667 m²,enhancing 20.94 kg/666 m² more than that of the control.The complex preventive measures of plant diseases and pests are as the followings,increasing propaganda and train,issuing the information of plant diseases and pests in time,choosing excellent varieties with disease resistance,producing strong seedlings,standardizing planting technique,using suitable fertilizers and pesticides,and carrying out uniform prevention.Standardized planting could increase economic benefits.It could increase 339.32 RMB((?))/667 m² more than that of the control.3.39 hundred million RMB could be gained per year if standardized planting area is spread to 667 million m²,which brings good economic,social and ecological effects.
