地膜植棉是一项新的先进科学种植方式。从生产实践和科学试验表明:地膜植棉在土、肥、水、种诸因素相同的条件下,增加一项塑料薄膜复盖,因棉田生态条件的改变,而获得较好的产量和优良纤维品质,提高经济效益。现以我县四年来的地膜植棉产量资料进行数理统计、分析。从中看出,地膜植棉不但经济效益高,而且自身也有一定的变幅。这种变幅与水的关系、与土壤肥力高低、棉田管理水平等等有着密切的相关性,这种相关性是否真实地客观反映地膜植棉的生产规律性,尚得进一步试验研究,得出准确的论证,以下见解,仅供参阅。
Plastic film cotton is a new advanced scientific methods of cultivation. From the practice of production and scientific experiment, it shows that under the same conditions of soil, fertilizer, water and seedling, the plastic film mulching adds a plastic film covering and obtains better yield and fine fiber due to the change of ecological conditions in the cotton field Quality, improve economic efficiency. Now my county four years of plastic film cotton yield data for mathematical statistics, analysis. It can be seen that cotton film mulching is not only highly economic, but also has its own amplitude. The relationship between this luffing and water is closely related to the level of soil fertility and the management level of cotton fields. Whether this relativity can objectively reflect the law of production of plastic film-mulching plants is still subject to further experimental research. Accurate argument, the following opinion, for reference only.
