Test method for reaction of peach garden soil to bag controlled slow release fertilizer

Abstract

The invention provides a test method for the reaction of peach garden soil to bag controlled slow-release fertilizer, which belongs to the technical field of agricultural testing. The test method comprises the steps of: (1) preparing a kind of fertilizer for testing, wherein the fertilizer comprises urea and monoammonium phosphate; mixing the urea and the monoammonium phosphate with potassium sulfate in a weight ratio of 41:14:40; after uniformly mixed, making the mixture into fertilizer bags of two kinds of 95g / bag and 47.5g / bag, and pricking micro holes on the bags through an industrial production line, wherein 0, 3, 5, 7 rows of holes are designed to be pricked on the bags of 95g / bag, and 0, 3, 5 rows of holes are designed to be pricked on the bags of 47.5g / bag; (2) arranging commercialfruit trees specialized mixed fertilizer; (3)testing the effect of different micro hole row numbers to the nutrient release of the bag controlled slow release fertilizer; (4) testing the effect of different temperatures to the nutrient release of the bag controlled slow release fertilizer; (5) testing the effect of the nutrient release of the bag controlled slow release fertilizer in field; (6) determining the release rate of the fertilizer according to the test in the step (5); and (7) performing data analysis according to the test result in the step ( 6). According to the test method for the reaction of peach garden soil to bag controlled slow-release fertilizer, the test method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of agricultural testing, in particular to a testing method for the reaction of bag-controlled slow-release fertilizers to peach orchard soil. Background technique [0002] Peach trees are sensitive to nitrogen. Excessive nitrogen will lead to vigorous growth of new shoots, and insufficient nitrogen will cause yellowing of leaves. Potassium has a significant impact on peach yield, fruit size, color, and flavor. Potassium nutrition is sufficient, the fruit is large, the fruit surface is plump, the coloring area is large, the color is bright, and the flavor is strong; the potassium nutrition is insufficient, the fruit is small, the color is poor, and the taste is light; the peach tree needs less phosphorus fertilizer and insufficient potassium. However, phosphorus deficiency will make the surface of peach fruit dull, the flesh soft, sour in taste, and spots or cracks appear on the peel from time to time. The r...

Problems solved by technology

[0004] In view of the defects in the prior art, the purpose of the present invention is to solve the unscientific technical problem of fertilization in the prior art, and provide a test method for the reaction of bag-controlled slow-release fertilizers to peach orchard soil. This assay method is simple and can accurately measure the The response of different rice varieties to slow-release urea is different, so as to select the best fertilization treatment method for the corresponding rice variety
