Embodiment 1

[0023] Embodiment 1: Extraction method of plant tissue extract A.

[0024] 150 parts of celandine whole herb, 20 parts of root bark and stem bark of bitter bark vine, 20 parts of sheep's hemp leaves, 10 parts of dried roots of scutellaria baicalensis, mash them with a tissue grinder and mix together, add EO-PO 10 parts of block polymer, 10 parts of epoxy rapeseed oil, 10 parts of methyl oleate, 270 parts of deionized water, after stirring with a mixer for 30 minutes, the mixed liquid was placed in a centrifuge at 5000 rpm for 20 minutes, The supernatant was taken to obtain the plant tissue extract A. wherein the ratio of mass and number of celandine whole herb, root bark and stem bark of bitter bark vine, leaves of Azalea chinensis and dried root of Scutellaria baicalensis is 15:2:2:1.

Embodiment 2

[0025] Embodiment two: fertilizer B.

[0026] Fertilizer B is nitrogen, phosphorus, potassium ternary compound, mixed fertilizer, adopts conventional technical means to make; Wherein total nitrogen (N) accounts for fertilizer mass fraction percentage and is 15%, and total phosphorus (P 2 o 5 ) accounts for 15% of fertilizer mass fractions, and total potassium (K 2O) accounts for 15% of fertilizer mass fraction percentage; the preparation method of fertilizer B is as follows: 100 parts of potassium nitrate, 70 parts of urea, 102 parts of superphosphate, 28 parts of talcum powder, mix homogeneously, drum granulate, sieve and retain Granules with a diameter of 1.8-2.0 mm are the fertilizer B.

Embodiment 3

[0027] Embodiment three: the preparation method of described medicinal fertilizer.

[0028] Medicinal fertilizer, its preparation method is as follows: several parts of the plant tissue extract A of Example 1, several parts of the fertilizer B of Example 2, A is sprayed on B by spraying equipment, so that it is evenly distributed in B, and dried by drying equipment The medicinal fertilizer is finally prepared; the drying means that the mass fraction of the water in the medicinal fertilizer accounts for less than 0.5% of the total mass fraction of the medicinal fertilizer; the drying temperature of the drying equipment is 40 ± 1 degree Celsius .

[0029] Table 1 Example 3 The different mixing ratios of A and B prepared by the method described in Example 3 were used to prepare the medicinal fertilizer.

[0030] Fertilizer No.

Abstract

The invention discloses a pesticidal fertilizer. The pesticidal fertilizer contains a plant tissue extract A and a fertilizer B, wherein the plant tissue extract A is extracted from a mixture of a celandine whole plant, celastrus angulatus root and stem bark, rhododendron molle leaf and dry scutellaria baicalensis root; the fertilizer B is selected from nitrogen, phosphorus and potassium containing ternary compound and mixed fertilizers, the total nitrogen (N) accounts for 15% of the fertilizer by mass, the total phosphorus (P2O5) accounts for 15% of the fertilizer by mass, and the total potassium (K2O) accounts for 15% of the fertilizer by mass. The invention discloses a preparation method of the pesticidal fertilizer. Mixed use of the plant tissue extract A and the fertilizer B has a synergistic effect of controlling a damping-off disease of hot pepper. The pesticidal fertilizer effectively, scientifically and reasonably utilizes resources, has a great significance in environmental protection and plays a positive promoting role in reducing agricultural input and increasing agricultural yield and income.

Description

technical field [0001] The invention relates to a medicinal fertilizer, in particular to a medicinal fertilizer containing plant tissue extract and a preparation method thereof. Background technique [0002] Pepper damping-off, damping-off is one of the important diseases of pepper seedlings. It is distributed all over the country. It is often caused by unsuitable temperature and humidity during seedling cultivation and extensive management. When the disease is severe, it often causes seedlings to fall and die in patches. Except that this disease harms capsicum solanaceae vegetables, vegetable seedlings such as melons, lettuce, celery, cabbage, cabbage, radish, onion can all be victimized. When the autumn seedlings are infected, the base of the stem is yellow-green and water-stained, and then turns yellowish-brown soon and develops to circle around the stem. The diseased tissue is rotten, dry and sunken, resulting in constriction. In the early stage of the disease, only a ...
