Embodiment Construction

[0015] (1) According to the requirements of the test design, mix the trace element fertilizer and the crushed soil uniformly in proportion to make the test fertilizer soil.

[0016] (2), according to the requirements of the test design, prepare several plastic containers with a diameter of 6--10cm and a height of 15--20cm; the plastic containers are required to have a certain strength, which can resist the penetration of the crop root system, so that the crop root system does not Able to penetrate plastic containers.

[0017] (3), test fertilizer soil is packed in plastic container, and the soil column height of test fertilizer soil packing plastic container is 5--10cm.

[0018] (4) In the area where the test crops are planned to be planted, several small pits are dug, and plastic containers containing the test fertilizer soil are placed in the pits, and the upper diameter of the containers is required to be close to the main root zone of the test crops.

[0019] (5) The test...

Abstract

The invention relates to a test method of a dry land trace element fertilizer, which belongs to the technical field of agricultural cultivation, and is characterized in that: according to the requirements of test design, uniformly mixing the trace element fertilizer and crushed soil by the ratio to prepare testing fertilizer soil, and putting the fertilizer soil into plastic containers with the diameter of 6 to 10cm and the height of 15 to 20cm; digging a plurality of small pits in a preset area for planting test crops, planting the plastic container into the pits, then planting the test crops into the small pits, and the main root areas of the crops are arranged above the plastic containers; and after the test, taking out the plastic containers, and moving the testing fertilizer soil out of a test area. The test method of the dry land trace element fertilizer integrates the characteristics of traditional potted plant tests and field tests, overcomes the impact of the field fertilizer tests on after-crops and the restriction of potter plant tests to the growth of the crops, can be reused in the second year without impacting the test on the basis of meeting the test requirements, and improves the utilization rate of a test lands.

Description

Technical field: [0001] The invention relates to a test method for dry land trace element fertilizer, which belongs to the technical field of agricultural cultivation. Background technique: [0002] Trace element fertilizer test in dry land soil is a routine test in soil fertilizer test. The conventional method is to apply the test fertilizer into the test area according to the design, for the crops in the test area to absorb, and then detect the growth effect of the test crops under different treatment conditions, so as to obtain the test results. However, after the applied fertilizer enters the test land, it has been mixed with the soil, forming a difference in the concentration of trace elements between the test areas, and cannot be used as a fertilizer test area again. Only after several years (generally more than 3 years) ) production to reduce the fertility differences among regional soils before they can be reused as fertilizer test areas. In this way, the actual wa...
