Benefits of technology

This invention provides an effective way to identify resistive or Salt Tolers (drought) plants from other types of crops that are better suited than others due to their ability to withstand water stress during different stages of growth without losing its effectiveness over time. By doing this, researches aimed at identifying these specific genotypes will help improve crop production by providing genetic resources for future breeding efforts.

Problems solved by technology

This patented describes how crops like cotton have been developed over time through various ways including growing them under different conditions (saltiness) levels. However, selecting suitable types has proven challenges due to their high sensitivity towards environmental stressors during harsh weather periods. Therefore, this problem needs to be solved before developing better gene combinations based upon these selected characteristics.

Embodiment 1

[0016] The method for screening drought-resistant, saline-alkali-resistant cotton varieties comprises the following steps:

[0017] (1) Manufacture artificial saline-alkali land: choose non-alkaline soil, add 30 grams of sodium chloride, 3 grams of magnesium chloride, 5 grams of magnesium sulfate, 2 grams of calcium chloride, 1 gram of sodium bicarbonate, and potassium chloride per liter of fresh water 1 gram, produce artificial alkaline water, pour 10 liters of this artificial alkaline water in the non-alkaline soil of every square meter and produce artificial saline-alkali land; Need to build the artificial greenhouse that can remove top at any time in the saline-alkali land that adopts, so that let Cotton plants get full sun and are protected from rain when it rains, keeping them dry;

[0018] (2) Cotton seed preparation: select the seeds of common cotton varieties to remove mildew and remove impurities, and then remove the cotton seeds, dry the cotton seeds in a 20°C drying o

Abstract

The invention discloses a method for screening a drought-resistant and saline-alkaline-tolerant cotton variety, and relates to the technical field of agriculture. The method for screening the drought-resistant and saline-alkaline-tolerant cotton variety comprises the steps of manufacturing artificial saline-alkali land, preparing cotton seeds, cultivating cotton, detecting drought tolerance of thecotton and detecting the alkali tolerance of the cotton; the cotton variety with the highest drought resistance and highest saline-alkaline tolerance is obtained through actual cultivation, the defects of wrong selection and missing selection can be overcome, and seed selection is more convincing.
