Example Embodiment

[0031] Example 1

[0032] 1. The insect-resistant organic fertilizer of the present invention consists of the following components and weight percentages, and is formulated to be 100kg:

[0033] Tobacco leaf scraps 80%; 80kg;

[0034] Calcium hydroxide 1%; 1kg;

[0035] Inert filler 19%; 19kg;

[0036] In the above components, the tobacco leaf scraps are tobacco plant wastes such as tobacco stalks and finely divided tobacco leaves or tobacco plant wastes such as tobacco stalks, tobacco stalks and finely divided tobacco leaves; calcium hydroxide is slaked lime; inert filler is straw coal or mud Pulverized coal. The channels for obtaining or purchasing the above components are the same as above, and will not be repeated.

[0037] 2. The preparation method of the above-mentioned insect-resistant organic fertilizer is carried out according to the following steps:

[0038] (1) After the tobacco leaf fragments are pulverized by a pulverizer, 80 kg of the pulverized tobacco leaf fragment...

Example Embodiment

[0044] Example 2 and Example 3 are also examples of the organic fertilizer of the present invention. Except for the content of the following components of the organic fertilizer, the components and the preparation method of the organic fertilizer are the same as in Example 1, and will not be repeated.

[0045] Example 2

[0046] The insect-resistant organic fertilizer of the present invention is composed of the following components and weight percentages: 100kg is prepared:

[0047] Tobacco leaf scraps 70%; 70kg;

[0048] Calcium hydroxide 3%; 3kg;

[0049] Inert filler 27%; 27kg.

[0050] In Example 2, the present invention was tested by the Analysis Center of the Agricultural Environmental Resources Research Institute of the Yunnan Academy of Agricultural Sciences: the organic fertilizer contains 42.2% organic matter, 4.3% total nitrogen, phosphorus pentoxide, and potassium oxide, pH 7.8, and moisture 7.9 %, reaching the implementation standard of NY525-2002 in the organic ferti...

Abstract

The invention discloses a pest-resistant organic fertilizer and a preparing method thereof, which belong to the technical field of organic fertilizer. The organic fertilizer consists of 70 to 80 percent of tobacco leaf scrap, 1 to 5 percent of calcium hydroxide and 19 to 27 percent of inert fillers; the tobacco leaf scrap can be tobacco plant rejected materials such as tobacco stem, tobacco stalk or fine tobacco leaf and the like, or cigarette industry tobacco plant rejected materials such as tobacco stalk and fine tobacco leaf; and the inert fillers can be peat or peat powder. The preparing method comprises the following steps of: respectively crushing the tobacco leaf scrap and the inert fillers through a crushing machine; sieving the calcium hydroxide by 80 meshes to prepare standby materials; and adding all the standby materials into a mixer for uniform mixing to prepare powdery or granular organic fertilizer. Compared with common organic fertilizer, the pest-resistant organic fertilizer has the advantages that the average soil insect resistance effect is 65.9 percent, the average field insect resistance effect is 61 percent, and the average increase in yield is 6.4 percent. The price of the pest-resistant organic fertilizer is approximately equal to that of the common organic fertilizer, the raw material is sufficient, the production process is simple, the pest-resistant organic fertilizer is energy-saving and environment-protective, and the method is easy to be mastered.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to an organic fertilizer with insect-resistant properties and a preparation method thereof. Background technique [0002] Tobacco plant wastes such as tobacco stems and tobacco leaf debris left in the cigarette industry are collectively referred to as tobacco leaf debris. In Yunnan Province alone, more than 200,000 tons of discarded tobacco leaves are produced every year. Therefore, how to treat and effectively utilize these tobacco leaves in a harmless manner is an urgent need in production. [0003] Tobacco leaf debris is rich in natural insecticidal ingredients - nicotine, according to the determination of organic matter containing 60.2%. Therefore, it is of great significance to develop new insect-resistant organic fertilizer products by using tobacco leaf debris, harmless treatment of tobacco leaf debris, environmental protection, and turning waste into treasure, a...
