Embodiment 1

[0036] Example 1: Inland saline-alkali land, with a salt content of 0.3 to 0.6%, 4 repeats, each repeating 0.3 acres. The control was the salt-tolerant variety Lunkang 6 cultivated in saline-alkali soil. Location: Dezhou City, Shandong Province.

[0037] 1. Choose salt-tolerant winter wheat varieties

[0038] Take Dekang 961 as the seed.

[0039] According to our indoor [germination rate (Gr), germination index (Gi) and vigor index (Vi) in 2% NaCl solution, see Table 1] and field comparison test [Dekang 961 (DK961) and Lumai under salt stress See Table 2 for the emergence rate (%) and emergence time (days) of 15 (LU15). Dekang 961 had the best seed germination and emergence under high salt pressure.

Abstract

The high-yield cultivation technique of wheat in saline-alkali field includes the following measures: selecting salt-resistant fall wheat species seed, using organic fertilizer as main fertilizer andusing microelement fertilizer for saline-alkali field crops as auxiliary fertilizer, selecting DEkang 961 as cultivatino species, before sowing, in tenth-twentieth of October, adopting wild flooding irrigation method, watering, salt-pressing and making moisture, after 3-5 days ploughing under to great depth and making land preparation, then film-covering and hole sowing with 1-3 days, after reviving in spring and when the first new leaf is grown and second new leaf is only produced spraying 20% mepiquat chloride paclobutrazol microemulsion on foliage.

Description

(1) Technical field [0001] The invention relates to wheat cultivation technology in saline-alkali land, belonging to the field of agricultural technology. (2) Background technology [0002] There are about 400 million hectares of saline land in the world. In my country, there are more than 23.4 million hectares of saline land. At present, most of my country's saline-alkali land is in a barren state, and the yield of a small part of saline-alkali farmland is also very low. Making full use of salt-tolerant genes in salt-tolerant crops to breed new high-yield salt-tolerant wheat varieties (lines) is the most fundamental, economical and effective method for improving the utilization of saline-alkali land, and it is also a subject of great social and economic significance. Internationally, the salt-tolerant breeding of wheat is mainly based on the cooperation of the International Center for Wheat and Maize Research (CIMMY. Mexico) and the British PBI for the distant hybridization of w...
