Embodiment 1

[0024] 0.8g potassium hexasulfate, 1.2g potassium pentasulfate and 1.7g urea were combined to form slow-release compound fertilizer 1 (the total mass of sulfur source: nitrogen, phosphorus and potassium source: 1:1.85). Prepare fungal PDA (PotatoDextrose Agar, PDA) culture medium according to the general method for microbial culture, add slow-release compound medicinal fertilizer 1 after high-temperature sterilization, and make the total concentration of medicinal fertilizer 3.7g.L -1 PDA culture solution, the PDA solution was poured into a petri dish and cooled and solidified, followed by Fusarium wilt (F.oxysporumf.sp.vasinfectum, race-7, provided by the Cotton Institute of the Chinese Academy of Agricultural Sciences), and placed in an incubator at 25 Cultivate at ℃ until the mycelium of the control group (no drug PDA) completely covers the plate, measure and record the colony diameter every day during the culture period, according to the formula

Embodiment 2

[0030] Referring to Example 1, investigate the effect of slow-release compound fertilizer 1 on Fusarium graminearum (F. graminearum, GeneBank: GQ466391, which is obtained from corn infected with stem rot in Zhengzhou, and is co-constructed by Henan Agricultural University and the Ministry of State Key Crop Science of Wheat and Corn). laboratory identification) of the bacteriostatic rate. Table 2 is the total concentration of 3.7g.L -1 The data table of the bacteriostatic rate of the slow-release compound fertilizer 1 against Fusarium graminearum as a function of inoculation time.

Embodiment 3

[0034]Referring to Example 1, investigate the slow-release compound fertilizer 1 against Fusarium moniliforme (F.moniliforme, GeneBank: GQ466389, which was isolated from corn infected with stalk rot in Zhengzhou, and was co-constructed by Henan Agricultural University and the Ministry of State Key Crop Science of Wheat and Corn). laboratory identification) of the bacteriostatic rate. Table 3 is that the total concentration is 3.7g.L -1 The data table of the bacteriostatic rate of the slow-release compound fertilizer 1 against Fusarium moniliforme as a function of inoculation time.

Abstract

The invention belongs to the technical field of chemical fertilizers and pesticides and relates to a slow-release compound medicinal fertilizer and application thereof. The slow-release compound medicinal fertilizer comprises a sulfur source, a nitrogen source, a phosphorus source and a potassium source, wherein the total mass ratio of the sulfur source to the nitrogen source, the phosphorus source and the potassium source is 1:(0.1-15); the sulfur source is polythionate or thiosulfate; the nitrogen source, the phosphorus source and the potassium source are prepared from one or more of urea, ammonium chloride, ammonium phosphate, diammonium hydrogen phosphate, ammonium dihydrogen phosphate, potassium nitrate, potassium carbonate, polythionate and thiosulfate. The slow-release compound medicinal fertilizer is prepared from one or more compounds of the polythionate or the thiosulfate and one or more components of common chemical fertilizers of the urea, the potassium carbonate, the ammonium chloride, the ammonium phosphate, the diammonium hydrogen phosphate or the ammonium dihydrogen phosphate according to the growth environment and the growth requirement of crops, so that the slow-release compound medicinal fertilizer is decomposed in a pH environment suitable for growth of plants, and nutrients and disease-resistant components required by the crops are slowly released.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers and pesticides, and relates to a slow-release compound medicinal fertilizer and its application. Background technique [0002] Chemical fertilizers and pesticides play an irreplaceable role in increasing production and harvest in modern agriculture, but they have been used separately for a long time, and the extensive use of chemical fertilizers and pesticides has also brought negative impacts on the environment. To reduce the amount of chemical fertilizers and pesticides, reduce the impact of both on the environment, and also reduce the labor of farmers. Combining chemical fertilizers and pesticides into medicinal fertilizers has been a research hotspot that scientific and technological workers have been working hard on. The existing preparation methods of various medicinal fertilizers can be classified into four categories: (1) chemical pesticides and chemical fertilizers are mixed ...
