Example Embodiment

[0035] Example 1 Appraisal of drought resistance of some late rice varieties in Hunan in 2012

[0036] The late rice varieties to be identified in this identification are Xiangwanxiandao No. 13, Yuzhenxiang, Nongxiang 18, Yueyou 9113, Wufengyou 308, Xiangyou 66, and Qingyou 109, which are seven approved late rice varieties in Hunan.

[0037] 1) Selection of control varieties: Xiangwanxian 12 was selected as the drought-tolerant control variety;

[0038] 2) Sowing and raising seedlings: sowing on the same day (June 10, 2012) to be identified late rice varieties and drought-tolerant control varieties, conventional seedling raising (using general water seedling raising method);

[0039] 3) Field preparation: A field of conventional land preparation is separated by field soil in the middle to form field I and field II with equivalent conditions. The water inflow and drainage of field I and field II are independent of each other;

[0040] 4) Transplanting: Transplanting on the same day (July...

Abstract

The invention relates to the field of crop planting, in particular to a method for identifying late rice head sprouting flowering period drought-enduring type varieties in field. The method comprises the following steps of 1) selecting a check variety, 2) sowing seeds and raising rice seedlings, 3) preparing the field, 4) conducting transplanting, 5) conducting drought treatment, and 6) identifying the drought resistance. According to the method, a late rice head sprouting flowering period variety comprehensive drought resistance formula is formulated, the check variety is set, the effect is easy to evaluate, the method is suitable for identifying a large number of drought varieties, the method is mainly used for identifying the drought resistance of the late rice head sprouting flowering period drought-enduring type varieties, the field simple identification method is adopted, and no complex instrument device is required.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a method for identifying drought-tolerant varieties of late rice in the heading and flowering stage in the field. Background technique [0002] Drought occurs widely in our country, and it has become more severe in recent years. my country's arid and semi-arid areas account for about 51% of the cultivated land, mainly distributed in Northwest and North China. Although the southern rice region has abundant rainfall, due to the uneven distribution of each month, strong seasonal droughts also occur from time to time. Drought has become the most important obstacle affecting rice production. According to statistics, the reduction in rice production caused by drought can exceed the sum of the reductions caused by other factors. Not only that, the drought also affected rice quality and rice planting area. Therefore, the reasonable evaluation, identification and research on the drought r...
