汉中平坝区种植制度改革的研究

通过对汉中平坝区种植制度演变规律的研究,指出种植业和畜牧业不配套是目前农业生产的主要矛盾。在实际调查和试验研究基础上,确定水田以引入“西引二号”饲料大麦,水旱地以开展间作套种为主的种植制度改革途径,并用线性规划方法对种植结构进行优化。结果表明,经结构调整,保证了当地主要粮食作物和经济作物面积的稳定和产量的提高,可基本解决因畜牧业发展而导致饲料不足的问题。

A Study of Reform of Crop Planting System in Flat Area of Hanzhong

Through studying the successive laws of crop planting system in the flat area of Hanzhong, the authors pointed out that the major contradiction in agroproduction is the imperfection of crop plantation and animal husbandry at present. Based on the practical surveys and experiments, it was determined that the reform of crop planting system should be to introduce "Xiying" No.2 feed barley to be planted in paddies and to carry out intercropping in irrigated and rainfed lands in the main. Also, linear planning method was empoyed to optimize the crop planting patterns. The results showed that the readjustment of crop planting patterns can ensure the stable planting areas of principal food crops and cash crops, and also improve crop yields. As a result, the problem of short of feeds in developing livestock production has been solved.
