摘要
为解决秸秆去向,把秸秆制成生物炭,在黄瓜生产中施用生物炭,对改良土壤有很好的效果.以纯土、纯基质(耶渣)为对照,土∶秸秆炭分别为5∶1、10∶1、15∶1的配比制作营养土,开展盆栽试验进行相关研究.结果表明:施用秸秆炭处理2(土∶秸秆炭为5∶1)土壤孔隙度增加32.19%,土壤容重降低31.34%,土壤抗张力强度减少,有利于种子萌发;黄瓜苗株高、茎径、真叶数与秸秆炭用量成正相关,瓜形与秸秆炭用量成反比;各处理产量大小依次为:处理2>处理3>处理4>处理1,产量随秸秆炭用量增加而增加,与纯基质相比,纯基质产量最优,但基质生产的成本远远高于秸秆炭配比基质.秸秆炭有利于黄瓜生产,同时解决了秸秆的去向问题,是循环农业发展的方向之一.
In order to solve the problem of the direction of straw, the straw is made into biological carbon, and the application of biological carbon in the production of cucumber has a good effect on improving the soil. The YISHION soil and the pure matrix (lord slag) were compared. The nutrient soil was made according to ihe ratio of soil and straw carbon such as 5: 1, 10:1 and 15: 1, and the pot experiment was carried out to conduct the related research. The results showed that after applying straw carbon treatment 2 ( the ratio of soiland straw charcoal is 5:1 ), the soil porosity increased by 32.19%, the soil bulk density decreased by 31.34%, and the soil tensile strength decreased, which was favorable for seed germination. The height of cucumber seedlings, the diameter of the stem and the number of true leaves were positively correlated with the dosage of straw charcoal, and the melon shape was inversely proportional to the dosage of straw charcoal. The yield and size of each treatment plan are as follows : treatment 2 〉 treatment 3 〉 treatment 4 〉 treatment 1, and the yield increases with the increase of the amount of straw carbon. Compared with pure matrix, the yield of pure matrix is the best, but the cost of matrix production is much higher than that of matrix with the straw carbon ratio. Straw carbon is beneficial to the production of cucumber, at the same time, it solves the problem of the direction of the straw, which is one of the directions of the development of circular agriculture.
