| Strawberry,belongs to the rosaceae in botanical classification,strawberry,due to taste delicious,nutritious,loved by the people,in recent years,with the development of the sightseeing agriculture,the local strawberry planting area increased significantly,but the economic benefit is not ascending increased with the increase of planting area,investigate its reason is not according to the different cultivation patterns suitable varieties,in addition,the low temperature is one of the main factors to limit its development.In view of the above situation,this paper studies the sunlight greenhouse cultivation pattern,plastic greenhouses to half for the cultivation mode and cultivation mode,the open country 3 different fruit economic characters of three varieties,the comparison of characteristics,phenophase,growth and results and compares the three varieties of reproductive characteristics,and studied under 5 ℃low temperature,the three varieties of different time of low temperature stress processing,the main physiological and biochemical index of SOD,POD,CAT,free proline,malondialdehyde,soluble sugar and soluble protein of strawberry hardiness,the influence of by the membership function method for comprehensive evaluation of three varieties of hardiness.The results are as follows:(1)different cultivation mode,the three varieties of fruit economic character,growth and results of characteristics and the comparison of comprehensive properties such as phenophase:different cultivation mode,the shape of three varieties,color bright,her love sweet,treasure to hand in the shape of early and all is conical,color pink,red,respectively,hani mostly short conical,part of wedge,the fruit is a deep red color.Under the greenhouse cultivation,three varieties showed good result characteristic,but luckily the inner quality of incense is better,more conform to the requirements of the harvest,the economic benefit is remarkable,secondly due to large treasure to pay early and the most simple fruit,is more conform to the requirements of the harvest.Although the taste of hani is sour,but mature period is early,can go public early.Therefore,in the greenhouse cultivation mode,the first choice is lucky,and baobao early life and hani can be matched with planting.Under the plastic greenhouse cultivation,the treasure to pay early and show good comprehensive properties,due to the mature period is the region’s peony festival,tourism people is more,the economic benefit is remarkable,her love sweet though intrinsic quality,but the yield is low,can be used as a high-grade picking,haney with colorful,although the taste is acid,but the yield is high,also can be used as auxiliary.Under open field cultivation,hani bright color,fruit size,taste sweet and sour,mature period,and is a tourist festival,many tourists and can be used as harvest,also can be used as processing,economic benefit is very significant,her love and treasure to pay early and due to the end of the period late harvested,thus can be used as a high-grade picking,auxiliary picking.(2)5℃ low temperature,a comprehensive evaluation on the three varieties of hardiness:with the extension of low temperature stress time,the three varieties of SOD were higher before the change trend of decline,but still keep the higher activity,hani increases the size of the largest,second respectively treasure handed in early life and her love.Xing xiang and hani’s POD is rising,and treasure to pay early and finally have the change trend of decline,but the decline is not large,treasure to pay early and increase the size of the largest,followed by Hani respectively and her love.Xing xiang and hani CAT increased first,after a slight drop,drop,treasure to pay early and the CAT has been rising trend,treasure to pay early and increase the size of the largest,followed by hani respectively and her love.The PRO of the three varieties finally showed an increase in the variation of the law,with the contrast of 53.66%in comparison with the contrast of 53.66%in the comparison with hani,and 1.03 times higher than that of baobao.Over time,the increase in the soluble sugar of hani was 1.92 times higher,Second respectively as fortunate and treasure to pay early birth,her love sweet biggest soluble protein increased,the second respectively as fortunate and treasure to pay early,in addition,the malondialdehyde hani constantly low,good cold resistance.According to the value of membership function,the cold tolerance of the three varieties was compared and the cold resistance was strong,and hani>baojiaozaosheng>xingxiang. |
