At the end of every cotton harvest, Cotton grower There are a lot of topics to talk about cotton varieties. Some say that a good variety has been added, and some have regretted choosing the wrong variety and reducing the output. They have deep expectations and concerns about cotton seeds in the seed market.

In the 9~11 months of this year, with the experts and technicians from the China Association of cotton technology in Hubei, Hunan, Jiangxi, Anhui and other provinces, the author took part in several field observation meetings of new cotton varieties with high yield, and exchanged the new cotton varieties with the relevant agricultural distributors and cotton growers in Jiangsu and Zhejiang provinces. Although some cotton producing counties and cities in Zhejiang, Anhui and Jiangxi provinces were affected by the influence of typhoons and waterlogging, cotton production was reduced in. The cotton production situation in Hubei, Hunan, Jiangsu and other provinces is relatively good, and high yield farmers are everywhere. Many of them are using cotton varieties to increase production. For example, Zhang Chuncheng, the 64 year old Party branch secretary of the Xinle brigade of the Diao Dong cotton seed farm in Hanchuan, Hubei, has planted 15 mu of cotton fields in China. The famous brand of China, the national variety of Hua Za cotton H318, and 735 mu of cotton seed yield per mu have been attracted by many local and foreign visitors.

Years cotton Production practice tells cotton farmers that good seed is the primary factor for cotton yield increase. From the survey conducted by the author, it is more urgent for farmers to increase the yield of cotton. The higher the yield is, the greater the demand for improved varieties. 農(nóng)民對(duì)良種的期盼表現(xiàn)在以下幾個(gè)方面：一是有的農(nóng)戶正在準(zhǔn)備選購(gòu)棉種，由于市場(chǎng)上棉花品種太多，讓人看得眼花繚亂，不知選哪一個(gè)品種好，希望有關(guān)部門(mén)進(jìn)行指導(dǎo);二是有的農(nóng)戶已經(jīng)認(rèn)準(zhǔn)了今年的增產(chǎn)品種，打算明年全部更換這個(gè)良種，怕市場(chǎng)斷貨不能完全滿足要求;三是不少農(nóng)民說(shuō)，今年表現(xiàn)好的良種，明年要繼續(xù)確保質(zhì)量，不要頭年好，次年差，三年地里“多、亂、雜”;四是在南方棉區(qū)，已經(jīng)習(xí)慣了采用育苗移栽技術(shù)，農(nóng)民們主張選用以轉(zhuǎn)基因雜交棉為主的抗蟲(chóng)棉種，擔(dān)心購(gòu)不到正宗的雜交棉種;五是在棉種價(jià)格上，很多農(nóng)戶說(shuō)，只要棉花良種貨真，哪怕價(jià)格高一點(diǎn)，也是可以接受的，就怕品種變味或者用雜交F2冒充F1。

From the point of view of cotton production dynamics, the next year's cotton production area will continue to decline in most places except for a few places. In order to effectively promote cotton production in the reverse trend, we must give full play to the advantages of cotton varieties. First of all, the agricultural authorities should guide the cotton farmers to choose cotton varieties suitable for local use according to the "sunshine training" work in winter and spring. Secondly, the high-yield varieties should have wide adaptability, high yield and resistance to stress; third, the selected varieties must have the marked varieties approved by the provincial crop variety Approval Committee. Cotton seed Entering the market; fourth, we should try to choose hybrid insect resistant cotton varieties, because the hybrid insect resistant cotton should increase about 15% compared to the conventional cotton under the same cultivation and management conditions; fifth, ensure that the large farmers can choose authentic varieties, and accelerate the extension and extension of the excellent varieties through their exemplary role; sixth, strengthen the technical guidance, do well the matching of the good laws, and track the whole process.
