农作物收获前进行田间测产,以初步估定地块的产量,做到心中有数。一般只要选点具有代表性,方法得当,测产细致,可以得到接近实际的数据。随着家庭联产承包责任制的推行,进行田间测产在农业统计中更有重要意义。进行田间测产主要有以下三种简易方法: (一)查测法测产在作物成熟后,通过查明农作物产量的构成因素,如禾谷类作物的穗数、粒数和粒重的具体数据,来综合推算单位面积的产量。要求每块地所选测点不少于3个,5亩地以上的地块所选测点不能少于5个。可用对角线等距布点,
Crop field harvesting before the test to initially estimate the yield of land, be aware of. As long as the general election as long as the representativeness of the method is appropriate, detailed measurement and production, you can get close to the actual data. With the implementation of the household contract responsibility system, field measurement is more important in agricultural statistics. There are three simple methods for field measurement: (1) The method of detecting and measuring production After the crop matures, by identifying the components of crop yield, such as the specific data of the spike number, grain number and grain weight of cereal crops , To comprehensively calculate the yield per unit area. Requires no less than 3 points for each site selected, more than 5 acres of land selected sites can not be less than 5 points. Available diagonal equidistant distribution point,
