Problems solved by technology

[0004] At present, there are many kinds of "plant drought resistance agents" on the market, most of which are technologies developed based on the needs of plants for some mineral elements and plant growth regulators. The drought resistance of plants is mainly enhanced through specific methods such as seed coating, seed soaking, and spraying. Water retention capacity, because it only emphasizes the change of a certain biological trait, ignores the overall drought resistance of the crop, resulting in complex product components and limited functions, which cannot solve the problem of crop drought resistance. Breeding, cloning of drought-resistant and water-saving genes, and the use of water-retaining agents to

Embodiment Construction

[0010] Yumai 49 was selected from the seed company of Henan Academy of Agricultural Sciences.

[0011] 1. Pretreatment:

[0012] Disinfection: select a few wheat seeds that are plump and full, with complete embryos, and use 0.1% HgCl 2 After disinfection for 15-20 minutes, rinse with tap water and distilled water three times respectively, and dry the water on the seeds with filter paper.

[0013] Seed soaking: Soak the seeds in distilled water for 24 hours.

[0014] Pregermination: Place the seeds in a petri dish and place them in an incubator at 28°C for 72 hours.

[0015] In order to make the obtained phenotypes universal, we adopted different planting methods: (1) Use small plastic tubes with vermiculite as a support, plant two seedlings in each tube, take ten tubes as a whole, and irrigate nutrients under the tubes (2) Plant in plastic pots with vermiculite as a support, plant 100 seedlings in each pot with a row spacing of 1 cm × 1.5 cm, and fill the pot with nutrient ...

Abstract

The present invention pertains to the agricultural technical field, relating to the application of sodium nitroprusside in drought resistance of crops. Sodium nitroprusside is confected into 10 to 30mg/L aqueous solution and then irrigated into roots or sprayed on leaves of crops. The crops processed by sodium nitroprusside in the seedling period can obviously improve the drought resistance, and after one week of natural drought, the water content still maintains high and the growth is recovered after drought rehydration. In addition, sodium nitroprusside can significantly promote the growth of wheat lateral root and plays an important role in improving the plant-root water absorption.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to the application of sodium nitroprusside in drought resistance of crops. Background technique [0002] Sodium nitroprusside is a powerful venous and arterial dilator. By increasing the venous compliance, the ventricular filling pressure will drop rapidly, and the arterial blood vessel expansion will reduce the systemic vascular resistance, thereby reducing the preload and afterload of the heart. Endocrine hyperactivation. Sodium nitroprusside is currently mainly used in the treatment of cerebrovascular, cardiovascular and other diseases to play a role in dilating blood vessels, and has become a widely used clinical drug. [0003] Drought is one of the main natural disasters in our country, and it often brings great losses to agricultural production in the north, especially to winter wheat, the main food crop in the north of our country. Drought has become one of the important e...
