当前肥料研究工作中,如何根据农民的先进生产经验,进行经济有效的施肥,从而获得农作物的增产,是一项迫切的研究任务.本试验即是在这一思想指导下进行的.在磷肥试验中,不仅要注意到磷肥直接对作物的肥效,而且还要研究其间接的肥效.根据1962年寿的磷矿粉、钢渣磷肥和过磷酸钙的盆栽试验结果证明:在四川重庆层紫色土施猪粪的基础上,只是钢渣磷肥对小麦有增产作用,另两种磷肥效果不显著,而蚕豆对三种磷肥的利用能力都很强,增产效果是很显著的.又根据本地农民经验,豆麦间作中的小麦可以获得增产.因此本试验是研究通过蚕豆根系对迟效性磷肥强力的吸收,并由其根系把可吸收性养分供给小麦,从而提高磷肥肥效和小麦产量.其结果是:小麦每盆籽粒产量为:无肥5.4克,单施猪粪10.9克,猪粪和磷矿粉10.8克,猪粪加钢渣磷肥14.5克,猪粪加过磷酸钙10.05克.而蚕豆籽粒每盆重量依次为7.8克,15.4克,21.85克,20.1克,24.25克.
In the current research on fertilizers, it is an urgent task to study how to apply fertilizers economically and efficiently in order to increase the yield of crops according to the advanced production experience of peasants.This experiment is carried out under the guidance of this idea.In the experiment of phosphate fertilizer , Not only to pay attention to the direct effect of phosphate fertilizer on crops, but also to study its indirect effect.According to the 1962 life of phosphate rock, slag phosphate fertilizer and superphosphate pot test results show that: in Chongqing, Sichuan purple soil facilities On the basis of pig manure, only the steel slag phosphate fertilizer has the effect of increasing the yield of wheat, while the other two kinds of phosphate fertilizer have no significant effect, while the broad bean has strong ability of utilizing the three kinds of phosphate fertilizer and the yield increasing effect is very remarkable. Wheat intercropping wheat can be increased.Therefore, this experiment is to study the strong absorption of delayed-acting phosphate fertilizer through the root system of Vicia faba, and absorbable nutrients from its roots to wheat, thereby increasing the fertilizer efficiency and wheat yield.The results are: Wheat grain yield per pot: 5.4 grams of fertilizer, single pig manure 10.9 grams, 10.8 grams of pig manure and phosphate rock, pig manure plus steel slag phosphate 14.5 grams, pig manure plus superphosphate 10.05 grams. Grain weight per pot were 7.8 g, 15.4 g, 21.85 g, 20.1 g, 24.25 g.
