Embodiment 1

[0037] A method for constructing a paddy field fertilization field plot test, comprising the following steps:

[0038] A. Choose 1 for the test field. According to the selection requirements of the test paddy field, the test paddy field selected for the example is located in Group 1, Jiahe Village, Bainihu Township, Xiangyin County, Hunan Province. The geographical coordinates are 28°44′41.6″N and 112°50′51.5″E. The paddy field is more than 20 hectares, the experimental field area is 1200 square meters, 500 meters away from the road, and 200 meters away from the farmers' houses, with good drainage and irrigation conditions and sufficient sunlight. The soil is the fertile paddy soil formed by the parent material of the lake deposits, which is a typical representative paddy soil type in the Dongting Lake area.

[0039] B. Community settings 2. The number of treatments in the example paddy field experiment is 9, and the number of experiment repetitions is 3 times. The length o...

Abstract

The invention discloses a construction method for a field plot trial of fertilizer application to paddy fields. Through the selection of a test field, ridges of plots and footpaths are constructed by repeatedly settling moist soil in a paddy field; a plot irrigation mode that main grooves are connected with small grooves is adopted so as to increase the repeated treatment times of each plot; the plots are set in a block so as to ensure that the density of transplants and the number of seedlings in the plots are identical. The construction method comprises the following steps: A, selecting the test field; B, setting the plots; C, constructing the plots; D, applying fertilizers to the plots; F, raising and transplanting seedlings; G, irrigating the plots; H, intertilling and weeding; I, controlling pest; J, harvesting rice; H, sampling soil and ground water. The test plots are simple in structure and low in construction cost, and the cross flow of water and nutrients among the plots are effectively avoided. Therefore, the construction method is suitable for various field plot trials of short-term and long-term fertilizer application, agricultural chemicals, varieties, irrigation, cultivation, discharge of greenhouse gasses, and runoff and leaching loss of nitrogen and phosphorus nutrients.

Description

technical field [0001] The invention relates to the technical field of agricultural research, and more specifically relates to a method for constructing paddy field fertilization field trials, which is suitable for application in various field trials in paddy fields. Background technique [0002] Field experiment is an agricultural scientific experiment method to study the relationship between crops and the environment under natural conditions in the field, using various traits, yield and quality of crop growth and development as indicators. Field tests can be divided into variety tests, cultivation tests, fertilization tests and pesticide tests according to the research content, and can be divided into dry field tests and paddy field tests according to the type of land. Field experiments can study the yield-increasing effect of new varieties, new products and new technologies under natural conditions in the field, objectively evaluate high-yielding varieties with various ex...
