Embodiment 1

[0067] (1) Variety selection

[0068] Select Teyouhang 1, Tianyou 998, Y Liangyou 1 and other super rice varieties that have been tested and demonstrated and are suitable for local planting, which have been certified by the Ministry of Agriculture as super rice varieties.

[0069] (2) Selection of the environment of origin

[0070] Select the field with flat surface, convenient drainage and irrigation, good water and fertilizer retention capacity; good tillability, plowing layer depth of 20-30cm; uniform soil fertility, soil organic matter content ≥ 20.00g / kg, total nitrogen ≥ 1.00g / kg, available phosphorus ≥ 10mg / kg, available potassium ≥ 50mg / kg, and fields with a pH value of 6.0-7.0 are planted with super rice.

[0071] (3) Cultivate strong seedlings

[0072] 1) Sowing period

[0073] For early planting, the daily average temperature should be stable above 12°C, and for late planting, the standard for avoiding the "cold dew wind" during flowering and pollination ...

Embodiment 2

[0128] Early and late construction in 2012 and early construction and late construction in 2013 implemented the present invention in Zhulian Village Committee, Gongguan Town, Hepu County, Guangxi Zhuang Autonomous Region.

[0129] The cultivated land area of ​​Zhulian Village Committee is 217.87hm 2 , the super rice variety planted in 2012 (including early cropping and late cropping) and 2013 (including early cropping and late cropping) is Y Liangyou 1. Among them, the planting area of ​​super rice in 2012 was 419.33hm 2 ; The planting area of ​​super rice in 2013 was 426.27hm 2 . In 2012, the implementation area of ​​the present invention was 410.53hm 2 , accounting for 97.90% of the area of ​​super rice, the contrast field area of ​​the present invention is not implemented is 8.8hm 2 , accounting for 2.10% of the area of ​​super rice; in 2013, the implementation area of ​​the present invention was 420.27hm 2 , accounting for 98.59% of the area of ​​super rice, the area ...

Abstract

The invention discloses a standardized cultivation method of super double cropping rice. Currently, the super double cropping rice is cultivated still according to a traditional method for cultivating ordinary rice, yield is not stable, the quality is not high, and grain safety and income increasing of farmers are seriously affected. The standardized cultivation method includes the technical measures of selection of varieties, selection of environment of producing area, robust seedlings cultivation, field cultivation and management, integrated control over plant diseases and insect pests and the like, and systematized standardized cultivation technology integration research of the super double cropping rice is carried out. According to a test result after 56 thousand of hm2 is popularized and applied, the yield of 667 m<2> reaches 456.67 kg / 667 m<2> averagely, the yield increase range reaches 42.57 kg / 667m<2> averagely, the rate of growth reaches 10.27% averagely, the increased income of every 667 m<2> reaches 100.58 RMB / 667 m<2> averagely, the cost for using chemical pesticide to control diseases, pests and the like is lowered, and the cost is saved by 6.5-7.2 RMB / 667 m<2>. According to the technical standard, the production of the super rice is indexed and scientized, the technical operability is high, the application effect is good, the standardized cultivation method is deeply popular by mass farmers, and the gained economic benefit, social benefits and ecological benefits are remarkable.

Description

technical field [0001] The invention relates to a standardized cultivation method for double-cropping super rice, belonging to the technical field of rice cultivation. Background technique [0002] Super rice refers to super high-yield rice, which refers to a new variety (combination) with a greatly improved yield on the basis of resistance and rice quality similar to that of the control variety (combination). Super rice varieties (combinations) refer to those bred by the combination of ideal plant shape shaping and heterosis utilization, etc., which have a large yield potential, and are equipped with ultra-high-yield cultivation techniques. Compared with existing rice varieties, the yield has been greatly improved, and A new rice variety that takes both quality and resistance into consideration. As of March 2014, there were a total of 111 super rice demonstration and promotion varieties named by the Ministry of Agriculture. With the continuous successful selection and pro...
