| For nearly 20 years of exploration in Xinjiang cotton production situation, and the current farmers in Xinjiang cotton production behavior and search the production costs are the key factors affecting farmers in Xinjiang cotton cultivation, this study controlled by looking for the China statistical yearbook and questionnaire way carries on the summary and model search, in the hope of understanding of the cotton production in China are fully, to make scientific guidance for guidance in Xinjiang cotton production. Results show that, since reform and opening up, the Xinjiang cotton production and the cotton production has the very good collaborative, presents the fast growth the tendency. Xinjiang cotton production in the contribution of the national cotton production plays an important role. Xinjiang cotton yield per unit area in a certain extent, affected the cotton yield per unit area on the national level, are steadily increasing trends. Xinjiang cotton planting area presents the fast growth the tendency,since reform and opening up the national cotton planting area shows the tendency of increase after the first reduce. The Xinjiang cotton industry is still very important in the agricultural production in Xinjiang, the Xinjiang cotton output per capita of volatility seems to have less effect on the national cotton output per capita. Changji, Northern Xinjiang lakeside town of cotton planting area and cotton production cost present scale economy u-shaped curve, the optimum planting area of 167.7· 667 m2, can get the lowest cost is 750.7 yuan/667 m2. Aksu kuqa cotton production cost and the relationship of economic optimum planting scale of cultivated area, when the area of 130· 667 m2 can obtain the least costs, minimum cost is 850yuan/ 667m2, Eastern Xinjiang, and planting area of curve also show U curve, when the area of21 ha can obtain costs for at least 1200 yuan; Xinjiang cotton growers the best scale economyof 21.2 ha of cultivated area, at the same time the corresponding minimum cotton production cost is 1067 yuan, but the realization of the optimal economic scale is uncommon in the small family unit; Under different irrigation mode in certain radioactive-polluted area in Xinjiang,drip irrigation benefit is 985.8 yuan/667m2, and the average for flood irrigation is only 600yuan/667m2, agricultural areas in xinjiang cotton cotton adopt best drip irrigation mode; Under flood irrigation cotton per 667m2 net income increased with the increase of planting area showed a trend of reducing the rise, then present a u-shaped quadratic function curve, is the best scale economy, when cotton planting area of 20.2 ha, can obtain the best economic benefits is 1538 yuan, the cotton per 667m2 irrigation mode with the increasing of planting area of the net income to the basic remain unchanged or smooth, not the so-called scale economy. Drip irrigation cotton net income per acre with cotton planting area has the economic scale, when the cotton planting area of 11.6 ha can harvest the biggest economic benefit, is 1669 yuan per 667 m2; Certain radioactive-polluted area in xinjiang cotton farmers per capita net income and cotton cultivation area of quadratic function curve, is the best returns. Corresponding to the cotton area of 445.6 acres, corresponding to the per capita net income 86052 yuan. Cotton planting area and yield per unit area scale economy. Get the best yield per unit area of 22.9 ha of cultivated area, the corresponding income is 2562 yuan. The Xinjiang cotton planting users for employees in the production process of cotton yield significant influence, has hired unit average income is in 1138 yuan, and no employment unit income is 1350 yuan, compared with workers, no worker family units of cotton net income increased by 18.6%, reached significant difference levels. In additional,We found the cotton yield is higher than buying machinery did not buy machinery, more than its increase the income 311 yuan. But the difference was not significant(p = 0.218)... |
