Hybrid cotton hole-tray seedling raising, transplanting and seed production technology

Abstract

The invention provides a hybrid cotton hole-tray seedling raising, transplanting and seed production technology which comprises the following steps: seedling raising; transplanting management; post-planting management; and breeding management. According to the hybrid cotton hole-tray seedling raising, transplanting and seed production technology, a hole-tray seeding raising and transplanting technology and artificial emasculation seed production technology are effectively combined and optimized, the seed production period is ahead of schedule and prolonged by 8 days to 10 days, seed production cotton ball bearing rate is increased by 18.45%, seed production output is increased by 42.6%, and hybrid cotton seed farm average seed per mu yield is enabled to be increased from 84.5kg to 120.5kg.

Description

technical field [0001] The invention relates to a cultivation technology, in particular to a hybrid cotton plug seedling cultivation, transplanting and seed production technology. Background technique [0002] Xinjiang is located in the hinterland of Eurasia, rich in light and heat resources, and is the largest area suitable for growing cotton in my country. The cotton planting area in our district has grown to nearly 26 million mu, and the total cotton output in 2012 accounted for 50% of the national output. Under the key support of the state, our district has achieved a steady increase in cotton yield and total output, and has now built the largest high-quality cotton production base in China, and has been identified by the state as a superior cotton industrial belt, with continuous area, total output, and transfer volume Ranked first in the country for 15 years. The cotton industry has become the pillar industry of the autonomous region and Corps. Cotton, as the main c...

Problems solved by technology

[0005] As of June 2012, 5 early-maturing hybrid cotton varieties have been approved in Xinjiang. Their yield, resistance, quality and other comprehensive traits are superior to those of conventional cotton varieties in the same period. The cost is high, and the area of ​​large-scale application in production in the past 10 years is less than 2 million mu, which is only one tenth of Xinjiang's annual cotton planting area

With the further improvement of the breeding and planting level in our region, the promotion of hybrid cotton will gradually accelerate, and the demand for seeds will further increase. Relying on the conventional seed production technology to produce hybrids, the yield is low and the price is high, and it is difficult to achieve a balance between supply and demand.
