Embodiment 1

[0025] see figure 1 , the paddy field fertilizer test field that prevents water and fertilizer from interlacing includes paddy field 7, and paddy field 7 is surrounded by field ridge 5; In paddy field 7, be surrounded by soil ridge 2 and form three repeated experimental areas, between adjacent experimental areas is isolated by irrigation and drainage ditch 8, The width of irrigation and drainage ditch 8 is 30cm.

[0026] The soil ridge 2 inwall of each repeat experiment area is provided with the first pinch plate 1, the second pinch plate 3 and the 3rd pinch plate 10, divides each repeat experiment area into four equal areas by three separate pinch plates 4 A test plot; an irrigation and drainage outlet 11 is provided on the side wall of each experimental plot adjacent to the irrigation and drainage ditch 8; irrigation and drainage outlet 11 places are inserted with an irrigation and drainage gate 6.

[0027] see figure 2 , the two ends of separation gusset 4 are all insert...

Embodiment 2

[0048] see image 3 , in paddy field 7, surrounded by soil ridge 2 to form four repeated experiment areas,

[0049] The two ends of separating pinch plate 4 are all inserted in 25cm in the soil ridge 2, and the bottom of pinch plate 4 is positioned at 15cm below paddy field furrow surface.

[0050] The bottom of the first gusset 1 in each test plot, the bottom of the second gusset 3 and the bottom of the 3rd gusset 10 are all positioned at 15cm below the paddy field border surface, and the height of the soil ridge and the ground gusset is 25cm .

[0051] The length of the irrigation and drainage outlet 11 is 30 cm; the length of the irrigation and drainage gate 6 is 50 cm, and both ends of the irrigation and drainage gate 6 are inserted in the soil ridge 2 .

[0052] The area of ​​each experimental plot is 40 square meters.

[0053] Other structures are with embodiment 1.

[0054] Embodiment 2 is applicable to the plot test of paddy field fertilizer that is applicable to f...

Abstract

The invention relates to a paddy field fertilizer experimental field capable of preventing mixing of water and fertilizer. The paddy field fertilizer experimental field comprises a paddy field, wherein ridges I are arranged on the periphery of the paddy field, more than three repeated experimental areas are defined by ridges II in the paddy field, and irrigation and drainage ditches are arranged between adjacent repeated experimental areas for isolation; buckle plates are arranged on the inner wall of the ridges II in each repeated experimental area, and each repeated experimental area is divided into more than two experimental subareas with equal size by more than one partition buckle plates; an irrigation and drainage water opening is formed in the side wall of each experimental subarea on the side adjacent to the corresponding irrigation and drainage ditch, and an irrigation and drainage gate is inserted in the irrigation and drainage water opening. PVC (polyvinyl chloride) buckle plates are used for producing the paddy field fertilizer experimental field, so that the workload for producing the paddy field fertilizer experimental field is reduced, and the occupation area for an experiment is saved; by means of the ridges and the buckle plates, mixing of water and fertilizer between the experimental subareas can be blocked, field animals can be prevented from going through the ridges, and the fertilizer experimental accuracy can be improved.

Description

technical field [0001] The invention belongs to the field of agricultural science research, and in particular relates to a paddy field fertilizer test field. Background technique [0002] Field experiment is one of the most important methods of agricultural scientific research and the most basic means of agricultural technological innovation. However, there are many uncertainties in field experiments, which are affected by many environmental conditions, which can easily lead to inaccurate test data or even failure. Therefore, it is the most basic requirement of scientific research to do everything possible to maintain a single difference in field trials. [0003] For fertilizer scientific research, it is necessary to ensure that fertilizers in different test plots cannot contaminate each other in order to obtain valuable test data. In the dryland plot test, the fertilizers in different plots can be separated by ditches or soil ridges between the plots to ensure a single di...
