The Effects of Silkworm Excrement Organic Fertilizer on the Hemp Yield

ABSTRACT

The ecological farming and organic fertilization are getting popular and required in time, when synthetic fertilizers and agrochemicals are used and easily overcome. In this article, organic farming of hemp (Cannabis sativa L.) is presented, and an innovative organic fertilizer the mulberry silkworm (Bombyx mori L.) breeding waste is examined. This insect breeding is a cheap source of waste, which gives very positive results on the plants yield. Such tests of hemp have not been carried out so far.

In this research, three repetition pots were prepared: with silkworm fertilizer 15 Mg∙ha⁻¹, 30 Mg∙ha⁻¹, and pots without fertilization (control). The amounts of three yields – total, straw, and seed – were measured. Moreover, the chemical composition of silkworm waste, soil, and hemp material was tested. The best results of fertilization were obtained in silkworm manure fertilization in dose 30 Mg∙ha⁻¹.

摘要

生态农业和有机肥在使用合成肥料和农药且易于克服的情况下得到了及时的普及和要求. 本文介绍了大麻的有机耕作（Cannabis sativa L.），并研究了一种创新的有机肥料-桑蚕（Bombyx mori L.）繁殖废料. 这种昆虫繁殖是一种廉价的废物来源，对植物产量产生了非常积极的影响. 到目前为止还没有对大麻进行过这样的试验. 本研究制备了3个重复罐: 用蚕肥15mg∙ha-1，30毫克∙ha-1和不施肥的盆栽（对照）. 测定了总产量、秸秆产量和种子产量. 此外，还对蚕渣、土壤和麻料的化学成分进行了测定. 施用量为30mg的蚕粪施肥效果最好∙ha-1型.
