Irrigation District, Wuwei grain and forage corn varieties comparison test results
Species are [im49, [im760, one 10 and Yu Shen 8703. Respectively, 140d,[link widoczny dla zalogowanych], 140d, 141d and 142d. Late maturing varieties than in the control 3 ~ 5d, is in late-maturing varieties. 2.2 Economic characteristics can be seen from Table 1. Shendan 1O height 275.3cm, ear length 2O. 6cm. 678.9 grains per spike, grain weight 266.0g,[link widoczny dla zalogowanych], kernel weight 38.3g, economic coefficient of 0.34, the Mu grains, grain weight, kernel weight maximum; [im824 height 327.1cm. Ear length 18.8cm. 568.2 grains per spike, grain weight 217 shuttlecock. Og, kernel weight 32.5z, economic coefficient 025; 1im760 height 3101cm. Issued long-18.8cm. 617.5 grains per spike, grain weight 210.7g + kernel weight 341g, Yu 8703 economic coefficient of 0.26 {height 300.7cm, ear length 22.2cm, grain number 62O7 weight 251 grains + draft. 7g, kernel weight 444g, economic coefficient 02,723 tested different varieties of grain yield of 7 grain equivalent yield of maize varieties 10206.35 ~ 1214286kg/hm (Table 2) which Shendan 1O Received: 2o011207 Author: Shu Ping set ( 1956 a) + women. Where on the Chuansha, Assistant Research brother. Soil and Fertilizer Institute is mainly engaged in the work sheet. 7, output and income area of strengthening the carbuncle enhance pest control pest control is one of the key measures to obtain high yield. Sowing with 5-methyl isofenphos granules 3Okg/hm withdrawal facilities, control root maggot and other soil pests, ensuring the whole seedlings. 3 leaves after emergence spraying 5O dichlorvos EC, 9O crystal trichlorfon 1000 times, prevention of rape leaf miner, flea beetle Phyllotreta, rape leaves a black seam. After the rape the following year in time turning green rolling oil sprayed 5O% plus 90% phoxim crystal trichlorfon 1000 times. Phyllotreta flea beetle control, black sewing leaves A larvae. Bolting to flowering stage in the 2.5 Decis EC 60 ~ 120g/hm. Lee EC sweep or 20 off 900 ~ 1300g/hm + 700kg water spray 1 or 2 times, may have to teach early flowering stage to control diamondback moth rape seed increase of EC with 4O 4O bacteria omethoate wettable powder Jing received 1000 times the net liquid spray to control aphids and Sclerotinia sclerotiorum. Gansu Agricultural Science and Technology No. 5 of 2002 G, ~ nsuAgr. Sci. andTechn. No. 520O215 species - the I - more resistant to significant differences in possession of 51 strictly the highest yield compared with the control for the 12142.86kg/hm varieties yield a single 2 18.97; followed by the 1 [m824 production ll777.78kg/hm. Yield than the single 2 l5.40; [im760, 1 [m49, Yu 8703, respectively, increase over the single 2 14.03,12.60,12.10, respectively, of 3,4,5-ranking position of the tested varieties 1} than in the control seat, single-species yield 3.58 Single 2. Analysis of variance, the grain yield differences were not significant biological yield of 2.4 different species can be seen from Table 3, tested seven varieties of maize biomass yield Yu 8703 in 27142.86 ~ 501I2.86kg/hm the highest - for 50142.86kg/hm, No. 2 than the control increase in 8124 alone; followed by the 1 [m824, than the control yield in a single 2 73.55; tim760, lim49 and Shen, respectively, compared with the control single-lO increase 44.92,[link widoczny dla zalogowanych],41.1 {and 30.98; Kang Shan 1, biological yield than the control, cut 1.89 compared with the control test new multiple small-minded poor. Yu 8703,1 [m824 and 1 [m49,[link widoczny dla zalogowanych], Shen single-1O, in a single 2, cool, 1 single pull biomass difference was significant, Yu 8703 and 1 [m760 significant difference in the level of ~ 1im760 with the single-2,[link widoczny dla zalogowanych], cool a single l No difference was highly significant {Shen single-l0 and the single 2, cool single-1 difference was highly significant 3 Summary of Test goblets results show that the tested seven ten varieties of grain yield Shendan 10 the highest, economic traits better than the other varieties, and its respect for the French I bow into the 1 [m824 and lim760, while the highest biomass Yu 8703, compared with CK 81.24. This four varieties of high yield, good grain yield, biological yield high, and Yu 8703,1 im824 and 1im760 straw with green mature, is the fine grain and forage species, can be used as filling in Wuwei City, Hirakawa promote the use of new varieties of pregnancy. Ten varieties of the 4 species than in the control late in the single 2 1 ~ 5d, is in late-maturing varieties, to ensure normal growth of corn, the best use of mulching Caipei.
