The project of pformation of science and technology achievements, "the demonstration project of high superiority pgenic insect resistant three line hybrid cotton Handan 98-1" has been studied through high-yield and high-efficiency seed production and supporting cultivation techniques. The three line hybrid cotton seed production system and seed quality standard have been perfected, and the high-yield cultivation technology of Hanza 98-1 has been developed and promoted.

Since the implementation of the project, the Handan Academy of Agricultural Sciences has worked hard for many years to develop the insect resistant three line hybrid cotton Handan 98-1, which is 0.45 of the wilt disease and 30 of Verticillium wilt, which is highly resistant to wilt and Verticillium wilt. Its resistance to disease is good, its resistance to Helicoverpa armigera reaches its resistance level, and its pesticide usage can be reduced by more than 60%. It has the advantages of early maturity, high yield, good quality, high lint percentage and low cost.

In order to better increase its production in production

potential

According to

In production

A set of high yield cultivation techniques for Hanza 98-1 was summed up.

The core of the technology is: on the basis of selecting suitable soil, applying base fertilizer, timely sowing and rational close planting, fertilizer and water pportation should follow the principle of "early chasing the bud stage fertilizer, early application of flower and boll fertilizer, adding top cap fertilizer at the later stage, supplementing foliar fertilizer with flocculating stage, keeping roots and protecting leaves, preventing premature senility", and "the principle of not watering seedling water, irrigating the bud stage water, irrigating flower boll water, and irrigating the floc water".

At present, a total of 167.6 kg of seed production has been achieved, and high-yield cultivation techniques have been developed and popularized to achieve 171.3 kg of cotton per mu and 1 million 480 thousand mu of acreage.

The establishment of parent seed research room and Germplasm Bank 580m2, 800m2.

The establishment of Hanza 98-1 parental breeding base is 200 mu, and the total seed production area is 11 thousand mu, and 16 high yield demonstration bases for hybrid cotton are established.

During the implementation of the project, 1 million 150 thousand kg of hybrids were produced, and the sales revenue was 32 million 200 thousand yuan. The profit was 8 million 395 thousand yuan and the social and economic benefit was 186 million yuan.

The implementation of the project has made remarkable achievements in reducing the cost of hybrid cotton seed production, expanding seed production scale, improving seed quality and yield, and has obvious promotion effect on the popularization of hybrid cotton in large scale, with remarkable economic and social benefits and wide application prospects.
