high lint yield
相关语句
  较高的皮棉产量
     It also showed that early- mature variety would produce high lint yield and pre-frost yield if its density was increased, its higher development rate and higher density would compensate for its less plant and heat limited in growth season for loss to a certain extent.
     结果还表明,早熟品种的生长发育速率较高,如适当增加其播种密度,可一定程度上弥补因生长季热量限制与植株小之不足所造成的损失,从而仍获得较高的皮棉产量和霜前花率。

The seed qualities of sixty-one upland cotton cultivars were meas-ured in this study.There was a high significant negative correlationbetween contents of rough(total)protein and fat(r=-0.8921,p<0.01).The average content of rough fat and the linoleio acid obtainedfrom this investigation were 34.77% and 54.83% respectively,the posi-tive correlation between them was presented,but not significant.Theaverage content of rough protein and the lysine reported here was40.308%,2.3687% respectively,the positive relationship between themwas significant(r=0.3477,p<0.05).The results derived from thisstudy suggested that there was a scope for genetic improving the contentof the linoleio acid and lysine in cottonseed simultaneously.Nineteen of61 upland cotton cultivars measured contained higher linoleio acid andlysine than the general mean.Among them,Xingtai 6871,Zhong Mian-suo 7 and Wan 73-10 were the cultivars with middle-mature and high-lint-yield;Liao Mian 3 with earliness;Also Sp-23,DPL 55,Burundi,DPL 61,DPL 41 etc.could be taken as a parent for improving cotton-seed qualities.

测定了61个陆地棉品种的种籽品质。粗蛋白和粗脂肪之间为极显著负相关(r=-0.8921)。粗脂肪平均含量为34.777%,亚油酸平均含量为53.84%,二者之间为正相关,但不显著。粗蛋白、赖氨酸平均含量分别为40.308% 2.3687%,二者之间为极显著正相关(r=0.3477)。61个陆地棉品种中,赖氨酸及亚油酸含量均较高的品种有19个,其中邢台6871、中_7、皖_(73-10),为中熟丰产品种;辽棉3号为早熟品种;SP_(23)、岱_(55)、布隆迪棉、岱_(61)、岱_(41)等,均可作为棉籽品质改良的亲本材料。棉籽仁是优质植物油脂及高蛋白食品和饲料的来源。它的不饱和脂肪酸占70%以上,亚油酸占50%以上;棉仁粉蛋白质含量高达50%以上。

In an experiment(?)carried out in Dafeng County,Jiangsu Province, in 1987, basal 3, 5 or 7 fruiting branches of cotton plants were removed at squaring stage to compare their effects on yield and disease control. Pourty days after treatment, the per plant numbers of fruiting branches in the 3 treatments were 13.09, 11.45 and 10.37, respectively, while those of the check plants averaged 14.95. However, the highest lint yield appeared in the treatment with 3 fruiting branches removed. In a set of experiments...

In an experiment(?)carried out in Dafeng County,Jiangsu Province, in 1987, basal 3, 5 or 7 fruiting branches of cotton plants were removed at squaring stage to compare their effects on yield and disease control. Pourty days after treatment, the per plant numbers of fruiting branches in the 3 treatments were 13.09, 11.45 and 10.37, respectively, while those of the check plants averaged 14.95. However, the highest lint yield appeared in the treatment with 3 fruiting branches removed. In a set of experiments with the removal of basal 3 fruiting branches conducted at 5 locations of Jiangsu Province in 1988, counted 42 days after treatment, the number of fruiting nodes of the treated plants was similar to that of the untreated; the square and young boll shedding was decreased by 5.28%; the boll number per plant was increased. The boll rot control effect of the treatment was higher than 57% (Table 4). In addition, the fiber quality and output value were increased (Table 3).

1987年在江苏大丰,试验摘除棉株基部1—3、1—5、1—7台果枝,40天后调查,果枝数分别为13.09、11.45和10.37,而对照为14.95;8月中旬铃病调查,相对防效为26.7%,57.2%和86.11%。回归分析表明,每株平均约摘除3台果枝时,可获得最高期望值产量。1988年,在江苏省的5个试点上,统一摘除基部3台果枝,42天后,果枝数与对照差异减少至1.64台,果节数几乎不减,而脱落率降低5.28%,单株成铃数超过对照,且提高了售棉等级,铃病防效达57%以上,效益显著。若结合药剂防治,防病增产效果尤佳。

The net photosynthetic rates,dark respiration rates and photorespiration rates offour cotton(Gossypium hirsutum L.)genotypes(Zhongmian 12,Lumian 1,PD4548,PD0109)were studied under the meteorological conditions of the cotton field atAnyang,Henan Province in 1986—1987.It was known that photosynthetic photoflux density(PPFD),temperature,air vapor pressure deficit(VPD),CO_2concentration were important agrometeorological ecological factors controling netphotosynthetic rate of cotton leaf.It was found that the photorespiration...

The net photosynthetic rates,dark respiration rates and photorespiration rates offour cotton(Gossypium hirsutum L.)genotypes(Zhongmian 12,Lumian 1,PD4548,PD0109)were studied under the meteorological conditions of the cotton field atAnyang,Henan Province in 1986—1987.It was known that photosynthetic photoflux density(PPFD),temperature,air vapor pressure deficit(VPD),CO_2concentration were important agrometeorological ecological factors controling netphotosynthetic rate of cotton leaf.It was found that the photorespiration rate,darkrespiration rate,light compensation point,and CO_2 compensation point of floweringand boll-forming stage of Zhongmian 12,the high yielding variety,were lower thanthose of other genotypes,but the photosynthetic rates of PD strains whose fiber quality is better were higher than those of others.It was considered that high netphotosynthetic rate,low photorespiration rate,low dark respiration rate,low CO_2compensation point,low light compensation point could be used as criteria in the selection of new cotton varieties with higher lint yield and better fiber quality.It was also possible to get good fiber quality and high lint yield through the improvement ofenvironmetal conditions.

1986—1987年于河南安阳在田间气象条件下对棉花(Gossypium hirsutum L.)遗传型不同的4个品种(中棉12、鲁棉1号、PD4548、PD0109)的净光合速率、暗呼吸速率.光呼吸速率等进行了研究,认识到棉田光合光量子通量密度、温度、空气水汽压亏缺、CO_2浓度等是控制棉花净光合速率的重要农业气象生态因子。研究发现,抗病高产品种中棉12的光呼吸速率、暗呼吸速率、光补偿点及铃期 CO_2补偿点均低于其他遗传型,而纤维比强度高的 PD 种质系的净光合速率则较其他遗传型高。因而认为可以以高净光合速率、低光呼吸速率、低暗呼吸速率、低CO_2补偿点、低光补偿点协调一致为目标,选育具高光合生产力的高产优质棉花品种,也可通过改善环境获得优质高产。
