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: Pot-tray seedling raising and hole-planting simulation machine-transplanted rice plot test-Shandong province machine-transplanted rice variety regional test

[0049] 1. Test purpose

[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 planting machine-transplanted rice seedlings in our province to provide scientific basis for variety certification and promotion.

[0051] 2. The tested varieties (lines)

[0052] There were 8 tested varieties (lines) (including control), numbered J1501, J1502,...J1508, of which J1501 was the control Shengdao 14.

[0053] 3. Experimental design

[0054] S1: Bed soil finishing

[0055] (1) Choose seedling fields: Choose the loam or clay loam rice fields with deep tillage, convenient irrigation and drainage, and even soil strength before winter as the seedling fields for the rice regional experiment.

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 pot-tray seedling raising and hole-planting method for simulating a rice seedling planting plot test, which is suitable for a comparison test of a planting rice seedling plot of a machine transplanted rice variety, and belongs to the technical field of rice breeding. Background technique [0002] Machine transplanting is a high-yield cultivation technique that uses a rice transplanter to efficiently transplant seedlings instead of original hand transplants, completely eliminating the heavy manual seedling transplanting. As the development direction of high-efficiency rice cultivation, mechanical transplantation has been basically popularized in developed countries. my country plans to basically realize the mechanization of rice throughout the country by 2020. However, the selection of rice varieties suitable for machine-transplanted rice is the key to the success or failure of the technology. Through the comparison test of varieti...
