Regulation Studies On Key Cultivation Technique For Yield And Quality Of Chickpea In Xinjiang

In order to verify the planting period effects, suitable planting density, and the best amount of nitrogen fertilizer of chickpea variety in Xinjiang, this article take Xinjiang local variety Awat 1 as a material, has separately studied the effect of different planting period, planting density, nitrogen fertilizer amount and irrigation system on Xinjiang chickpea's growth and the yield and the quality, through the field experiment. The main conclusions are as follows:1. In the different planting time circumstances, with the planting period postponed, the plant birthing period of chickpea were shorten, the time to reach the maximum leaf area index was advanced, the amount of dry matter accumulation per plant were decreased, the No.of effectual pods per plant and the No.of granule per pods were remarkably reduced, granule weight were not very related to the planting period. Along with the planting period postponed, the chick-pea protein content, the VB2 content, the Asiatic petroleum acid content presents increasing tendency, the palm acid content presents declining trend, the Vitamin B1 content and the oleic acid content presents reduces after increasing, and the difference among each treatment attain remarkable level. But the planting period to be not remarkable to the flax acid content affects. The results expresses, on this experiment condition, optimum time of planting chickpea variety Desi(Beiyuanchun shrink) in Xinjiang is about April 8~ April 15.2.With the increase of the chickpea planting density, the plant birthing period were advanced, plant height were heightened, LAI were increased, dry matter accumulation per plant were decreased. The No.of effectual pods per plant remarkably reduced with the increase of density. The No.of granule per pod and the granule weight were not very related to the plant density. The protein content, flax acid content and the twenty carbon alkene acid content are increased with the increase of density. The comprehensive performance of 445 thousand plants per ha was the best, with the highest yield 5946.09 kg per ha, and the quality is also very good.3.Along with the nitrogen fertilizer increase ,plant height ,branch number ,stem thick, the length of each branch were decreased after increasing .N2 trentment attain the highest level.In the early growing period ,the influence of nitrogen fertilizer on dry matter accumulation per plant was not significant ,but in graining period, the difference attain the significant level. The trend of pod number per plant, seed number per pod and seed weight are same to its yield trend, all present decreasing after increasing trend.N2 treatment attain the highest level.and present significant difference beween each treatment. The economical yield present increasing trend along with increasing the amount of nitrogen fertilizer, and the difference between each treatment attain the significant level. The yield of N2 treatment is the highest, attain 3759.703 kg/hm2. The yield of each treatment from high to low respectively is N2> N 1> CK >N3, the highest yield was increased 110.49%to the lowest yield .With the increase of nitrogen fertilizer, chickpea's protein content, palm sour content and oil sour content were increasing, vitaminB1content was decreased after increasing, the second oil sour content was attain significant level between each treatment, and have not relation to the VB2 content. Under this experiment condition, the most suirable quantity of nitrogen fertilizer is about 150kg/hm2.4. With the increase of infusing water amount ,plant height ,branch number ,the length of each branch ,the total number of nodes on main stem ,dry matter accumulation per plant ,the valid pods number per plant and its parameters were decreased after increasing ,and the difference between each treatment attain an significant level .With the increase of infusing water amount ,chickpea seed's protein content ,palm sour content and oil sour content were decreased .All have an negative relation to the amount of infusing water .and the second oil sour present gradual increasing trend.VB1 content was increased ,after attain the biggest value on treatment B ,the vitamin content on the contrary reduced with the further infuse of water amount.VB2 content was decreased after increasing .The comprehensive performance of the treatment of infuse water at early flower time and prosperous flower time were the best. The yield attained 5721.75 kg/hm2, and the quality is good.
