Test method for reaction of Clawson vine to bag controlled slow release fertilizer

Abstract

The invention provides a test method for the reaction of Clawson vine to bag controlled slow-release fertilizer, which belongs to the technical field of agricultural testing. The test method comprisesthe steps of: (1) preparing a kind of fertilizer for testing, wherein the fertilizer comprises urea, calcium superphosphate, monopotassium phosphate, organic fertilizer, and ferrous sulfate; (2) making slow release bags from common kraft paper, and pricking 10 holes on one face of each bag, wherein the diameter of each hole is 5 mm; (3) utilizing field micro-plot trial, and setting seven different fertilizer treatments; selecting 5 Clawson vine with the same vigor and with no diseases and insects, and repeating each treatment three times, wherein the soil fertilization is implemented by dipping a hole with the depth of 40 cm and 30 cm away from the root; (4) determining Chlorophyll and leaf area 2 weeks after each time of fertilization; (5) measuring the yield and quality of each plot; (6) determining the net photosynthetic rate, the transpiration rate, the air hole conductivity, and the intercellular CO2 concentration of the Clawson vine leaf; and (7) performing data analysis according to the test results in steps (4) to (6). According to the test method for the reaction of the Clawson vine to the 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 method for testing the response of Cressen grapes to bag-controlled slow-release fertilizers. Background technique [0002] China is a big agricultural country, and it is also the largest producer and consumer of chemical fertilizers in the world today. The application of chemical fertilizers was a major achievement in China's agricultural production in the 20th century, especially in grain production. Especially in the later period, it played a decisive role in the sustainable development of national grain production. [0003] Xinjiang is the main grape producing area in my country. Since the late 1990s, the development of viticulture in Xinjiang has been very rapid, and it is the fastest growing period in history. From the regional distribution point of view: both the northern and southern Xinjiang have developed a lot, with Changji, Ili, Turpan, Aksu, Kashgar an...

AI Technical Summary

Problems solved by technology

[0004] In order to improve the yield and quality of grapes, the optimal fertilization treatment method is needed to improve the quality and yield of grapes while improving the utilization rate of chemical fertilizers; in the prior art, there is no test method for using different fertilization methods to study grapes. Fertilizing grape vines through traditional experience cannot meet the current situation of grape development
