Embodiment 1

[0014] A preparation for improving the emergence quality of sweet sorghum in saline-alkali land, which consists of sweet sorghum seed soaking agent and sweet sorghum seedling spraying agent;

[0015] The sweet sorghum seed soaking agent is composed of the following components by weight percentage: 0.03% betaine, 0.0003% propionyl brassinolide, 0.004% ascorbic acid, 0.5% potassium dihydrogen phosphate, 0.015% vitamin B, wood Plain zinc carbonate 0.003%, manganese sulfate 0.001%, magnesium sulfate 0.005%, trehalose 0.001%, boric acid 0.006%, and the rest is water;

[0016] Accurately weighed with a ten-thousandth balance: betaine 0.015g, propionylbrassinolide 0.0015g, ascorbic acid 0.02g, potassium dihydrogen phosphate 2.5g, vitamin B 1 0.075g, lignin zinc carbonate 0.015g, manganese sulfate 0.005g, magnesium sulfate 0.025g, trehalose 0.005g, boric acid 0.03g, dissolved in 500mL of water.

[0017] The sweet sorghum seedling spraying agent is composed of the following component...

Embodiment 2

[0020] The experiment was carried out in a light incubator. The tested variety is Yajin 2, provided by Beijing Sangliang Technology Development Center. Select seeds that are full in size and shape, disinfect them with 5% hypochlorous acid solution for 5 minutes, rinse them with distilled water three times, rinse them completely, and then dry them under the sun until the water content of the seeds is below 14%. Sweet sorghum seed soaking agent and clear water (control) were used to soak the seeds, and after soaking for 12 h, they were placed indoors to dry for later use. Sow the soaked seeds in a plastic pot with an upper diameter of 16 cm and a lower diameter of 11 cm. The pot is a mixed substrate of vermiculite: yellow sand = 1:1 (volume ratio), and 8 seeds are evenly sown in each pot. at 1cm. Use 120 mmol·L -1 The 1 / 2 concentration Hoagland nutrient solution of NaCl evenly waters the substrate. Place the plastic pots at a diurnal temperature of 28 / 20oC and a photosynthe...

Embodiment 3

[0027] This embodiment was tested and implemented at Jinhai Farm Tidal Flat Test Base (120°50′59″N, 32°57′59″E) in Dafeng City, Jiangsu Province. The average salt content of the soil in the 0-20 cm plow layer of tidal flat saline-alkali land was 0.3%, and the test variety was Liaotian No. 1, which was provided by Liaoning Academy of Agricultural Sciences. Set up 3 repetitions, each plot area is 44.8m 2 , the sowing date is May 10, 2011, and the harvest date is November 3, 2011. Planting with equal row spacing, row spacing 60cm, density 7000 plants / mu, open field direct seeding. Carry out preparation treatment according to the formula of embodiment 1, take equal amount of clear water as contrast, dosage 30 L / mu. The main implementation steps are as follows: Soak the seeds with sweet sorghum seed soaking agent before sowing, and then sow them in ditches after drying. After 15 days of sowing, the seedlings are fixed, and one seedling is reserved in each hole. At the same time, t...

Abstract

The invention discloses a preparation for improving the seedling emergence quality of sweet sorghum in saline-alkali soil, and relates to the technical field of agricultural production. The preparation is composed of a sweet sorghum seed soaking agent and a sweet sorghum seedling spray, and concretely comprises betaine, propionyl brassinolide, ascorbic acid, potassium dihydrogen phosphate, vitamin B1, zinc lignin carbonate, manganese sulfate, magnesium sulfate, mycose, boric acid, and the balance of clear water. Seeds are soaked in the sweet sorghum seed soaking agent before sowing, the soaked seeds are aired at room temperature, the aired seeds are sowed, and foliar spraying of the sweet sorghum seedling spray is carried out twice in the trefoil stage of seedlings. A method for regulating the phytohormone physiology and exogenously supplementing mineral nutrients is adopted to enhance the salt resistance of saline-alkali soil sweet sorghum seedlings, promote seedling emergence, protection and growth of saline-alkali soil sweet sorghum and improve the biological output of sweet sorghum stems and the output of the sweet sorghum grains.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a preparation and a use method for improving the emergence quality of sweet sorghum in tidal flat saline-alkali land. Background technique [0002] About 20% of the world's soil is salinized. The high concentration of salt in the soil causes osmotic stress and ion stress poisoning to crops, which affects the growth of crops and leads to a decline in crop yield. The development and utilization of saline-alkali land has become a world problem in agricultural production. There are about 27 million hm2 in the inland and coastal tidal flat areas in northwest my country 2 The above-mentioned saline-alkali soil and secondary saline-alkali land have become important restrictive factors for the sustainable development of agriculture in our country. Sweet sorghum is an annual herbaceous plant belonging to the Gramineae Sorghum genus. It is a high-density energy plant that ...
