为了掌握农作物产量,在作物收获前,往往要进行田间测产。在实行农业技术承包合同制中,还利用测产来确定承包地块的产量。农作物田间测产,只要选点有代表性,方法得当,测算细致,可以得到接近实际的数据。田间测产的方法有三种。1.目测法这种方法是根据农业生产的基本条件和农作物的长相,考虑到增产技术措施和气候条件的影响,凭眼力和经验来评定农作物单位面积产量的。搞好目测估产,应该着重
In order to grasp the crop yield, before the crop is harvested, it is often necessary to conduct field test. In the implementation of agricultural technology contract system, but also the use of production to determine the output of contracted plots. Crop field test, as long as the selected points are representative, method is appropriate, measured carefully, you can get close to the actual data. There are three ways to measure production in the field. 1. Visual method This method is based on the basic conditions of agricultural production and the appearance of crops, taking into account the technical measures to increase production and the impact of climatic conditions, with eye and experience to assess crop yield per unit area. Do a good job of visual assessment of production, it should be emphasized
