中耕追肥是农业增产的重要措施之一.适时的中耕追肥,可以改善土壤的蓄水性,提高土壤肥力,并促进作物的生长发育,从而提高作物产量.追肥所用的肥料,可为有机肥料及无机肥料.追施无机肥料时,可以液体状态喷射到作物表面(如磷肥),亦可以干粉或结晶颗粒施入作物根系附近的土壤中.本文主要叙述后一种.进行中耕追肥,可利用现成中耕追肥机、中耕机改装成的中耕追肥机,及创制的小型简易中耕追肥机.在进行中耕机改装及简易中耕追肥机的创制时,应注意农业技术对追肥的如下要求:(1)施肥量的范围要大,适合于各种作物的施肥量要求;(2)排肥均匀,故障少;(3)追肥
Cultivation topdressing is one of the important measures of agricultural production.Cropsted timely top dressing, can improve soil water storage, improve soil fertility, and promote crop growth and development, thereby increasing crop yield.Apple fertilizer used for organic fertilizers and Inorganic fertilizer topdressing inorganic fertilizer, the liquid state can be sprayed onto the surface of crops (such as phosphate fertilizer), can also be dry powder or crystalline particles applied to crop roots near the soil.This article mainly describes the latter species. Cultivation top dressing machine, cultivator modified into the top-dressing fertilizer machine, and the creation of a simple simple top-dressing fertilizer machine.In the cultivation of tillage machines and simple cultivation of top-dressing machine creation, should pay attention to the technical requirements of top dressing on the following requirements: (1) fertilization The range of the amount should be large, suitable for a variety of crop fertilizer requirements; (2) fat evenly, less failure; (3) top dressing
