我县位於黔北,地处大娄山脉西部,地表起伏大,海拔高差悬殊,气候立体分布,属黔北单(双)季稻作区。全县共有稻田19.9万亩,占总耕地面积的32％,水稻产量占全县粮食总产量的40％,水稻总产长期徘徊在8000～9000万斤,平均单产400～450斤,属水稻低产县。在近20万亩稻田中,按单产水平可分三个等级(如表一),中、下等田占70％左右,面积约14万亩,是我县水稻生产上的拖腿田,同时也是发展我县水稻生产的潜力,上等田占30％,但单产水平也只有700来斤,与高产地区和本县高产田块相比,也还有潜力可挖。为了加速水稻生产的发展,我们在省
My county is located in northern Guizhou, is located in the western part of the Dalai Mountains, the surface undulating, altitude difference, the three-dimensional distribution of climate, is a single double (double) northern Guizhou area. The county has a total of 199000 acres of paddy fields, accounting for 32% of the total cultivated area, rice production accounted for 40% of the county’s total grain output, total output of rice hovering at 8000-90000 kg, with an average yield of 400 to 450 kg, is a low yield of rice county. In nearly 200000 acres of paddy fields, according to the level of yield can be divided into three levels (Table 1), middle and lower fields accounted for about 70%, an area of about 140000 acres, is my county rice production drag legs, at the same time But also the potential for developing rice production in our county. The upper farmland accounts for 30% of the total output. However, the yield per unit is only 700kg, which is still higher than that of high-yielding areas and high-yield plots in this county. In order to accelerate the development of rice production, we are in the province
