Problems solved by technology

At present, the method of transplanting seedlings in seedling fields or seedling trays to establish plots is mostly used. There are shortcomings such as seedling raising in seedling fields is slower than machine-transplanted seedling trays, and the number of seedlings in seedling trays is inconsistent. Criteria for transplanting seedlings: neat, even, straight, complete, and strong

Embodiment

[0048] Example: Pilot planting simulation machine-transplanted rice plot test in pot-pan seedling cultivation——Regional test of machine-transplanted rice varieties in Shandong Province

[0049] 1. Purpose of the test

[0050] Identify the high-yield, stable-yield, adaptability, stress resistance and quality characteristics of each tested variety (line), and screen out the rice varieties suitable for the promotion of planter transplanting in our province, providing a scientific basis for variety approval and promotion.

[0051] 2. Participating varieties (lines)

[0052] Eight varieties (lines) were tested (including the control), numbered J1501, J1502, J1508, and J1501 was the reference Shengdao 14.

[0053] 3. Experimental design

[0054] S1: bed soil preparation

[0055] (1) Selection of seedling field: select a paddy field with loam or clay loam soil that is deeply plowed before winter, convenient for drainage and irrigation, and uniform in soil fertility as the seedling f...

Abstract

The invention discloses a method for simulating mechanized rice transplanting plot experiment by pot rice seedling hole planting, and belongs to the technical field of a rice breeding technology. The problem that mechanical transplanting is difficult to realize because of a relatively small area of a mechanized rice transplanting plot is overcome. According to the method, a rice seedling throwing and raising technology and a rice variety regional test technology are combined so as to achieve requirements of a mechanized rice transplanting technology; mechanized transplanting rice varieties which are suitable for locally planting are screened out by quantitative pot seedling for seedling throwing, and stimulating rice mechanical transplanting by fixed-point hole planting; the mechanized transplanting rice varieties replace conventional hand-transplanted seed-bed seedlings or mechanized-transplanting tray-nursing seedlings; manual rice seedling separating and transplanting is changed into pot seedling fixed-point pot planting; the transplanted rice seedlings are quick in reviving and good in premature, and have the characteristics of having nutrient soil in roots of mechanized-transplanting rice seedlings, being not damaged in roots during seedling separating, being straight in transplanted seedlings, consistent in seedling quantity per planting hole, quick in reviving, early in tillering and the like. According to the method, the accuracy and the scientificity of the mechanized rice transplanting plot experiment are improved.

Description

technical field [0001] The invention relates to a method for pot-pan seedling raising hole planting to simulate rice machine-transplanted plots, which is suitable for comparative tests of machine-transplanted rice variety plots, and belongs to the technical field of rice breeding. Background technique [0002] Machine transplanting is a high-yield cultivation technique that replaces the original hand transplanting with high-efficiency transplanting by a transplanter, which completely relieves the heavy manual transplanting. As the development direction of high-efficiency rice cultivation, machine transplanting has been basically popularized in developed countries. Our country plans to realize the mechanization of rice in the whole country by 2020. However, screening out rice varieties suitable for machine-transplanted rice seedlings is the key to the success of the technology. By conducting comparison tests on plot varieties, we can screen out rice varieties suitable for mac...
