| Jize County is the famous pepper hometown in China,known as the leading county of pepper industry in China.Pepper industry has become the pillar industry of jize county and local farmers to increase income and get rich.However,there were a series of outstanding problems according to the investigation,such as the yield effect and economic benefit of different cultivation patterns were not clear,the poor fruit quality due to the serious disease,which restricted the sustainable and healthy development of the pepper industry of Jize County.This paper studied the cultivation pattern and cultivation technology of pepper by the field and experimental,so as to provide technical support for the promotion of pepper industry in Jize County.The research conclusions were as follows:1.In recent years,the cultivation area and yield of jize pepper show an increasing trend year by year.The cultivation area and yield were 3971 hm~2 and 176,000 tons respectively in 2016,the cultivation area and yield increased to 5603 hm~2 and 234,000tons respectively in 2018.The main variety of pepper is yangjiaohong pepper in Jize County,which accounts for more than 80%of the total cultivation area of pepper.There were five provincial leading pepper processing enterprises in Jize,and more than 200processed types of products were selling around the domestic market and more than 10countries and regions.The main cultivation patterns of pepper were single cultivation and intercropping.The main diseases were virus and anthracnose of pepper.2.To study the effect of intercropping pattern on yield and benefit of pepper,four cultivation patterns of wheat/pepper,maize/pepper and wheat/maize/pepper and single cropping were set.The result shows that interplanting patterns can efficiently lower the soil temperature and reduce light intensity.It also shows that intercropping patterns can obviously lower virus disease rate and fruit rot rate and decrease the damage of pest borer of fruit to pepper.The pattern of wheat/maize/pepper was the best one among the different patterns,it increase was 34.33 kg/667m~2 than the control.3.The growth and yield of pepper were researched in the different color plastic film mulching,the results showed that plastic film mulching could significantly improve soil moisture content,improve the insulation performance of the soil,increase the pepper plant height,stem diameter,number of fruit weight and yield results,raising the quality of pepper fruit effect,and inhibit the growth of weeds and pepper production,the influence of different color mulching film on pepper growth and yield and the influence from highest to lowest were black plastic film mulching>blue plastic film mulching>silver gray plastic film mulching>transparent plastic film mulching.4.The pepper disease was serious in Jize,the virus disease and anthracnose were the major disease,there are ten kinds of high-efficiency fungicide were screened for control the disease of virus and anthracnose of pepper.The result showed that the best pesticide control virus disease of pepper were Zhibingling and 20%virus A than other pesticides,the control effects were 73.45%and 68.96%,respectively.The best pesticide control anthracnose of pepper were 10%difenoconazole WDG and 250 g/L azoxystrobin SC than other pesticides,the control effects were 83.75%and 79.26%,respectively.5.The agronomic traits and yield of pepper that VDAL was applicated was researched,the results showed that VDAL can efficiently enhanced the plant growth,increased the yield,fruits value and chlorophyll content.The concentration of VDAL of3.33 mg/L was the best one among the different concentration. |
