Embodiment Construction

[0031] Example:

[0032] Guizhou Hongsifang Agricultural Development Co., Ltd. in Cengong County, Guizhou Province introduced the high-quality hybrid rice two-line combination "Fengliangyou 4" from Anhui in 2009 for seed production. Through the one-year trial production in 2009, the performance of this variety is better than that of Anhui, but the output still cannot meet the requirements of large-scale promotion. After 3 years of exploration, through the improvement of cultivation methods, the application of bioregulation, flowering period adjustment, pest control and other measures, the yield per mu has been greatly increased. The yield per mu has increased from 120 kg introduced in 2009 to about 300 kg. In 2013, the seed production area of ​​"Fengliangyou No. 4" in our county reached 4,500 mu, with an average yield of 310 kilograms per mu and an output value of 5,270 yuan per mu.

[0033] The specific method is:

Abstract

The invention discloses a method for increasing the seed production yield of hybrid rice 'Fengliangyou No.4'. According to the method, an improved variety 'Feng' 9311 is taken as a male parent and an improved variety 'Guangzhan' 63S is taken as a female parent, and the improved variety 'Feng' 9311 is combined with the improved variety 'Guangzhan' 63S for hybrid seed production to produce seeds of the hybrid rice 'Fengliangyou No.4'; the method specifically comprises the following steps: (1) carrying out seed breeding; (2) raising rice seedlings; (3) transplanting the rice seedlings; (4) carrying out field management including the processes of fertilizing, applying 'Tiaohuabao' (a farm chemical), preventing and controlling pest and disease damage and applying '920' (a farm chemical); (5) pollinating; and (6) harvesting. Through the measures of improving a cultivation technology, applying a bio-regulator, adjusting a flowering phase, preventing and controlling pests and diseases and the like, the acre yield of the seed production of the hybrid rice 'Fengliangyou No.4' is greatly increased and is increased to 300kg from 120kg, so that the large-area seed production popularization of the hybrid rice 'Fengliangyou No.4' is achieved; the method is suitable for popularizing the cultivation of the hybrid rice 'Fengliangyou No.4'.

Description

technical field [0001] The present invention relates to seeds of crops, specifically, it belongs to a seed production method, and more specifically, it belongs to a hybrid rice seed production method. technical background [0002] The hybrid rice "Fengliangyou No. 4"-National Approved Rice 2009012, is a fine variety approved by the Anhui Provincial Crop Variety Approval Committee in 2006. This variety is an indica two-line hybrid rice. Planted in the middle and lower reaches of the Yangtze River for one season of mid-season rice, the average growth period is 135.3 days, which is 0.1 day longer than the control Ⅱ You 838. The plant type is compact, the growth is luxuriant, the leaves are straight, the color changes well at maturity, the bud sheaths and leaf sheaths are green, the tip of the lemma is colorless and has no awn, the effective number of panicles per mu is 161,000 panicles, the plant height is 124.8cm, and the panicle length is 24.2cm. The total number of grains ...
