甘蓝尖椒新品种及新栽培技术模式研究与推广

经4年试验示范推广,在冀东加苫加后土墙型冷棚中,摸索出甘蓝尖椒新品种及新栽培模式,即选用新品种甘蓝精选8398,尖椒冀冬35。精选8398在8月下旬至9月上旬播种,定植密度67 500株/hm2;冀冬35在11月下旬播种,单株定植,密度46 500株/hm2。试验表明:甘蓝精选8398平均产量54 225 kg/hm2,收获期集中在元旦、春节,比对照中甘11增产6 525 kg/hm2,增产率达12.03%,产值高29 520元/hm2;尖椒冀冬35平均产量78 430 kg/hm2,4月上旬采收,比对照朝研牛角椒提前25 d左右上市,增产19 530 kg/hm2,增产率达24.90%,产值高41 075元/hm2。该模式平均纯效益161 312元/hm2,比传统栽培模式高78 189元/hm2,在京、津、冀等北方地区有着广泛的推广价值。

The New Cultivation Technique for New Cabbage and Pepper Variety and Its Popularization

The new cultivation technique for Jingxuan 8398(new cabbage variety) and Jidong 35(sharp pepper variety) was studied for 4 years experiment,demonstration and popularization in Luannan county,Hebei.The optimum sowing time and planting density of Jingxuan 8398 and Jidong 35 is from the last ten-day period of August to the first ten-day period of September and 67500 plant/ha,and during the last ten-day period of November and 46500 plant/ha respectively.The average yield of Jingxuan 8398 was 54225 kg/ha,6525 kg/ha higher than CK(Zhonggan 11) and the output value was 29520 yuan/ha higher than CK(Zhonggan 11) because the harvest time concentrates in the period of New Year's Day and the Spring Festival.The average yield of Jidong 35 was 78430 kg/ha,19530 kg/ha higher than CK(Chaoyanniujiao pepper) and the output value was 41075 yuan/ha higher than CK(Chaoyanniujiao pepper) because the harvest time was 25d earlier than CK.The average benefit by using the cultivation technique is 161312 yuan/ha,78189 yuan/ha higher than the traditional cultivation method.Therefore the new cultivation technique should be popularized in Beijing,Tianjin and Hebei.
