Problems solved by technology

However, in actual production and application, it is found that the total amount of nitrogen, phosphorus, and potassium in this type of chemical fertilizer is generally below 2%, so the fertilizer efficiency is low, and it does not have drug effect, so its yield increase rate is low, and disease prevention The ability to resist disasters is poor, and it is increasingly unable to meet the needs of the development of modern agricultural production

example 1

[0037] Example one: Dongtai City Shifei Station uses the foliage spraying of the present invention, and the concentration of 0%, 0.1%, 0.2%, and 0.3% with the present invention's content is used as a comparative test respectively, and the results show that: the concentration of 0.2% increases production by 13.6% on average. %, 0.1% and 0.3% two concentrations, respectively increase 10% and 11.4%.

[0038] Example 2: The coastal area of ​​Yancheng City is an area with a high incidence of cotton wilt. The city's soil and fertilizer station used the cotton field with fusarium wilt to spray the aqueous solution containing 0.2% concentration of the present invention as a comparative test. The test results showed that the average number of bolls per plant increased by 3.16 compared with the control field, the total number of peaches per mu increased by 9480, the average boll weight increased by 0.37 grams, and the yield per mu increased by 24.6%. The test results reached a signific...

example 3

[0039] Example three: the Institute of Vegetables of Jiangsu Academy of Agricultural Sciences applies the present invention to the impact of Yanghua radish output as a comparative test: 3.3 square meters of plot area, repeated three times, contrasting arrangement, adopting agricultural sprayer to spray dilution of the present invention, treatment group Spray 1000 times liquid for the first time, and spray 500 times liquid for the second time. The control group was sprayed with water. The cultivation and management of the two groups were the same. The test results showed that the radish yields of the treatment group and the control group were 24.9 jin and 21.5 jin, respectively. Compared with the control group, the average yield of the treatment group increased by 15.7%.

[0040] The present invention has passed the quality inspection of Jiangsu Provincial Health and Epidemic Prevention Station, and its result and evaluation are: according to the interim standard for classifi...

Abstract

The invention discloses a leaf fertilizer which is mainly applied to the leaf spraying of crops. The leaf fertilizer comprises the following constituents in percent by weight (%): 15-25% of urea, 5-15% of potassium dihydrogen phosphate, 10-20% of potassium oxide, 5-10% of zinc sulfate, 15-25% of borax, 5-15% of manganese sulfate, 1-4% of ferrous sulfate and 10-15% of magnesium sulfate. Compared with the prior art, the leaf fertilizer has the characteristics of insecticide-fertilizer dual effects, nutrition ingredient completeness, high concentration, low cost, no toxicity, remarkable disease and disaster prevention effects, convenience in use, large yield increase amplitude, applicability to a variety of soil and a variety of crops, and the like; and with the application of the leaf fertilizer, the economic benefit of agricultural production can be obviously increased, so that the leaf fertilizer is a highly-desirable agricultural composite chemical fertilizer.

Description

technical field [0001] The invention discloses a foliar fertilizer, in particular to a compound chemical fertilizer which has double effects of medicine and fertilizer and is especially suitable for foliar spraying, and belongs to the technical category of chemical fertilizers. Background technique [0002] Existing chemical fertilizers of this kind have a great variety and are too numerous to enumerate. Among them, "Penshibao" produced by Dianbo in Guangxi, "Ye Mian Bao" produced in Beijing, and "Cuizhu Brand Leaf Fertilizer" produced in Guangdong, etc. , have relatively high market sales, have made a greater contribution to the development of agricultural production, and achieved better economic and social benefits. However, in actual production and application, it is found that the total amount of nitrogen, phosphorus, and potassium in this type of chemical fertilizer is generally below 2%, so the fertilizer efficiency is low, and it does not have drug effect, so its yiel...
