Problems solved by technology

The liquid culture method and the sand culture method cannot fully simulate the field conditions and are completely different from the soil environment, thus limiting the potential of crop varieties and affecting the screening effect, and the operation process is cumbersome and difficult to control

Embodiment Construction

[0012] It was applied to wheat and sweet potato crops from 2005 to 2008, and the phosphorus-efficient genotypes Xumai 856 and Xushu 27 were screened out. Xumai 856 variety has been popularized and applied on a large scale in Huaibei area, while Xushu 27 has been widely used in low-phosphorus red soil areas of Henan, Liaoning, Jiangxi and Guangxi provinces, as well as in the hilly areas of Huanghuaihai, showing higher yield and higher yield than local varieties. Stable production, welcomed by farmers.

[0013] As shown in the accompanying drawing, there are 4 rows (repetitions) of field test plots, and 9 test plots 1 are set in each row. ), there are 80 centimeters of wide inter-district roads 2 between the sub-districts; 100 centimeters of wide repeating roads 3 are arranged between adjacent rows, and repeat four times.

[0014] Fertilize according to the design of long-term fertilizer positioning test, NPK treatment: 150kgN, 75kgP per hectare per season 2 o 5 、112.5kgK 2 ...

Abstract

The invention discloses a method for screening phosphorus-efficient genotypes of crops, which belongs to the field of evaluation on crop variety resources. 20-year-old soil fertilizer is used for long-term located testing, NPK (nitrogen, phosphorus and potassium) fertilizer and NK (nitrogen and potassium) fertilizer with evident difference in phosphorus nutrient are used to treat soil, and screening of phosphorus-efficient genotypes of the crops is performed on a field. The method includes: dividing the field into a plurality of test plots, and building cement ponds around each test plot for isolation; randomly planting test varieties into the test plots, using no less than ten plants of each variety, repeating planting for four times, and performing same managements; calculating the single plant yield in each repeat, using an average as the singe plant yield in each repeat, and using the averages of the four repeats as final yield results for analysis and evaluation. The method has the advantages that the method is more comparable and more reliable than the fluid-culture method and the sand-culture method using a greenhouse and tests using field soil at different places, and ideal phosphorus-efficient genotypes can be screened out to be directly used as material for selection, production and application of new varieties.

Description

technical field [0001] The invention relates to the technical field of crop variety resource evaluation, innovation and new variety breeding, in particular to a method for screening crop phosphorus-efficient genotypes. Background technique [0002] Phosphorus is a non-renewable mineral resource in nature, with 107 million hm in my country 2 About 2 / 3 of the soil in the farmland is severely deficient in phosphorus. The seasonal utilization rate of phosphorus fertilizer is generally only 5% to 10%, plus the after-effects of crops, generally no more than 25%, and the rest of phosphorus is fixed by the soil and becomes insoluble phosphorus. There are significant differences in phosphorus efficiency between different crops and even different varieties of the same crop, so people pay more and more attention to screening and cultivating new crop varieties with high phosphorus utilization efficiency and strong ability to activate soil non-available phosphorus. Most breeders use li...
