| Yongchang county is a large agricultural county in Gansu province.It is also the main production base of high altitude summer food in Gansu province,the main producing area of beer barley and the tourism area of oil and vegetable tourism.In recent years,Yongchang county takes advantage of natural,agricultural resource advantage and location advantage,develops characteristic economy,and actively promotes the standardization of high quality and high yield plateau summer vegetables and field crops construction.Yongchang agricultural products gradually realize the specialty,security,diversity and varieties.After many years of development,Yongchang county has formed the three pillar industries with high altitude summer food,beer barley and rapeseed tourism.But local agricultural development encountered many problems.Single cultivation crop variety and variety degeneration problem are become the problem urgently to be solved in the new stage of agricultural development in Yongchang county.These vegetable crops and field crops are the main crops in the region,and it is important to accelerate the replacement of these crops.Therefore,to carry out the cabbage,carrots,baby food,cauliflower,broccoli,celery,six kinds of vegetables and barley,rape varieties introduced two kinds of field crops,test and research,and through the test for rapeseed were suitable for cultivation of planting technology.The main results are as follows:1.Through the cabbage,carrots,baby food,cauliflower,broccoli,celery,coldresistance,such as vegetable varieties comparison experiment,the adaptability,high yield and high quality comparison,select the varieties suitable for local production.Cabbage varieties angel cooked sex is moderate,leaf is light green,round flat circular is relatively tight,has insect resistance and good shelf quality,production of 108 t/ha,the variety yield increases by 8.43%,which is suitable for the varieties of planting on the region;The variety of carrot varieties Niagara has a good comprehensive character,high commodity rate,with a yield of 96.6 t/ha,compared with 32.37% in contrast with napa,which is suitable for large area cultivation in Yongchang county.It has a good appearance,good commercial property,good ripening,good compactness,high quality of food,high resistance to disease,high quality of single ball.The output of the crown south spring was up to 158.5t/ha,compared with the control variety,the golden doll increases by 12.49%,and the yield of the earth pearl was 156.5 t/ha,which was 11.08% higher than the control.These two kinds of dolls are suitable for the promotion of planting in Yongchang county.Cauliflower variety Chevrolet ball white,the shape of the ball is round ball,the texture is compact and delicate,the selfcovering good,the commercial sex is good.The weight of single ball reached 0.81 kg,and the yield reached 49.5 t/ha.Compared with the control variety,the white spirit increases by 6.1 t/ha,which is suitable for the planting and promotion of Yongchangcounty.Red queen broccoli varieties comprehensive properties,its tight tender for mushroom,not easy to loose flower,flower small,fresh scent,good quality,good shelf quality,production reached 39.4 t/ha,hardy varieties excellent increased by61.47% than control,is suitable for planting on Yongchang varieties;Celery varieties royal princess good color,good disease resistance,good single ball weight,yield than other varieties of obvious advantages,yield of 162.3 t/ha,varieties than control,San Diego,increase of 8.3 t/ha,the cultivars can be used as Yongchang celery preferred varieties.2.The two barley varieties,HF-05-1-11 and 0416-1,which are suitable for the promotion of planting in Yongchang county,were selected by comparison experiment of barley variety.The yield of the species HF-05-1-11 was 74.17 cm high,the ear length was 7.97 cm,the grain number was 22.33,the grain weight was 46.27,and the yield was highest to 6.2t/ha in all the test varieties,and the yield increased by 7.15%compared with that in the control group.Variety 0416-1 was 74.17 cm tall,the ear length was 9cm,the grain number was 22.67,the 1000-grain weight 40.7,the yield was 6.1 t/ha,and the yield was 0.3t/ha,and the yield increased by 5.52 %.3.The selection of two rapeseed oil varieties and the oil 309 for the promotion of planting in Yongchang county were selected through comparison test of rape variety.These two varieties have more effective branches,the number of single wilts and single kernels are large,the grain weight is large,the yield is high,and the yield advantage of other varieties is huge.The yield of the crown oil was as high as 4.7 t/ha,and the yield increased by 1t/ha compared with that of the control variety,which increased by 27.03%.The yield of the oil 309 was 4t/ha,and the yield was 0.3t/ha,which was 8.11%.4.The technology of mulching film mulching with rapeseed and mulching has been shown to increase the yield and economic benefit of local rape.The yield of black film mulching was 6.2 t/ha,compared with the production of the white film mulching,the yield increased by 24.6%,and the yield increased by 1.8t/ha,compared with the conventional level,with a yield increase of 27.3%.In total,cabbage varieties angel,carrot varieties Niagara,baby food varieties crown south spring emperor queen,cauliflower varieties Chevrolet,broccoli varieties,celery varieties royal princess excellent comprehensive properties,high yield,these vegetable crop varieties suitable for planting on Yongchang county;The wheat varieties HF-05-1-11 and 0416-1 panicle grain number,mu panicle number,1000-grain weight and other yield components are reasonable,the yield is high,can be promoted in Yongchang county;The effective branches,the number of kernels and the number of kernels in the oil and vegetable varieties were high in yield,which was suitable for the popularization and planting of Yongchang county.The effect of black film covering oil yield is obvious,which is suitable for the cultivation of local rape. |
