测土施肥是目前世界各经济发达国家的一项常规农业技术,我国近年来也在大力推广应用。测土施肥有三种方法,一是土壤养分丰缺指标法,二是计划产量施肥法,三是土壤养分诊断法。1986年,我们在过去研究的基础上,于农六师一○三团采用计划产量施肥法在哈密瓜上进行了试验。 材料与方法 供试品种为赛红,计划产量设亩产3吨、3.5吨及4吨三种,试验面积共6亩。哈密瓜需肥参数据1984年研究结果定为每产100公斤果实需有效氮373克,有效磷118克,有效钾621克。
Soil testing and fertilization is a common agricultural technology in economically developed countries in the world. China has also vigorously promoted its application in recent years. There are three methods of soil testing and fertilization, soil nutrient abundance index method, the second is the planned yield fertilization method, the third is soil nutrient diagnosis. In 1986, on the basis of past research, we conducted a trial on the melon using the planned yield fertilization method in the 130th group of farmers. Materials and methods The test varieties were race red. The planned output was 3 tons per mu, 3.5 tons and 4 tons. The total test area was 6 mu. Hami melon fertilization parameters According to the 1984 study results for each 100 kilograms of fruit required effective nitrogen 373 grams, 118 grams of available phosphorus, 621 grams of available potassium.
