摘要
新疆光能资源十分充裕,光能生产潜力较大。热量资源比较丰富,利于玉米、棉花等喜温作物的种植,光照丰富,温差人对作物和瓜果产量提高和优质有利。越冬气候条件较差。平原地区降水稀少,变率大,地区季节分配不均;春旱严重,气象灾害多。因此,要充分利用光能资源优势,提高光能利用率。针对地区光热不均衡的特点,应因地制宜,采取不同熟制和不同种类作物栽培,北疆南部可种植喜温作物,南疆和东疆可建立长绒棉商品生产基地,吐鲁番盆地可大力发展葡萄、瓜果和长绒棉等经济作物。要合理开发利用水分资源,发展灌溉,科学用水,提高水的利用率。
Xinjiang enjoys rich light energy resources with a great productive potential as well asrich heat resources,being favourable to the growth of hygrophilous plants including corn andcotton.Richful sun shining and great diurnal temperature are favourable to the improve-ment of qualities and yields of crops,melons and fruits,but climate conditions for overwinterare very poor.There is less rainfall in the plain area with a great varying frequency and un-even distribution regionally.Sprining drought is serious with more meterological disasters.Therefore,the advantages of light energy resources should be fully utilized by improvinglight energy use efficiency.Different cropping systems and different crop varieties should beadopted in accordance with local conditions characterized by uneven distribu-tion of light andheat resources.Accordingly,hygrophilous plants can be adopted to the south part of Northxinjiang.The long-fiber commer-cial cotton producing bases will be set up in the south andeast Xinjiang.Grapes,melons and fruits as well as other industrial crops such as long-fibercotton can be developed in Tulufan Basin.Moisture resources should also be used and devel-oped rationally.Also,attention must be paid to developing irrigation and improving water useefficiency.
