Embodiment 1

[0026] Embodiment 1 quinoa seed treatment

[0027] 1. Quinoa Seed Treatment

[0028] Select 10 plump seeds of the same size in the same batch, each with 100 grains, and adopt the following 5 treatments, each with 2 grains, totaling 200 grains:

[0029] (1) Seeds are soaked in warm water at 65°C for 2 hours, and natural cooling is not required during this process;

[0030] (2) Bihu (0.136% red·inb·brassica wettable powder) 20000 times dilution solution soaking for 1h;

[0031] (3) Seeds were soaked in 0.1% hydrogen peroxide for 30 minutes, then rinsed with water for 3 times, and then spread to dry;

[0032] (4) Soak the seeds in warm water at 50°C for 30 minutes, then remove the seeds and drain the water, soak them in 1% potassium permanganate solution for 15 minutes, then rinse them with water for 3 times, and then spread them out to dry;

[0033] (5) Soak the seeds in sterilized water for 2 hours (CK).

[0034] 2. Germination test and salt stress

Embodiment 2

[0055] Embodiment 2 quinoa sowing depth

[0056] In May 2017, planting experiments under different conditions were carried out in Dongyihe Village, Yongan Town, Dongying City, Shandong Province, with a test plot of about 130m 2 , medium fertility, sandy loam soil, 20cm surface soil salt content is 3.72g / kg. Carry out the test according to the following method: cover 2 sides of high-quality foreign soil on the surface of the test plot, plow it, plow it to a depth of 20cm, then water it thoroughly, spread 800kg of farmyard manure after 7 days, and then plow it for the second time, plow it to a depth of 10cm; Then flatten the land to make it even and delicate, and then divide it into sub-districts of about 6m×2.4m on average, with a ridge width of 35cm, a ridge surface of 20cm, a ridge height of 15cm, and a row spacing of 35cm. Each plot has 5 ridges, and each ridge is a repetition. Seeds were soaked in 0.1% hydrogen peroxide for 30 minutes, then rinsed with water for 3 times, t...

Embodiment 3

[0069] Embodiment 3 quinoa cultivation

[0070] The planting test was carried out in Dongyihe Village, Yongan Town, Dongying City, Shandong Province from 2017 to 2018. The test plot is about 1.5 mu, with medium fertility and sandy loam soil. The salt content of the 20cm surface soil is 3.53g / kg. It belongs to the type of saline soil and the last crop for cotton.

[0071] Divide the land evenly into 9 blocks, each block is about 100m 2 , perform a randomized block test as follows:

[0072]

[0073] According to the following methods for quinoa cultivation management:

[0074] (1) At the end of October, cover the surface layer of the plot with high-quality foreign soil, 5 square meters per mu; then perform the first plowing, and the plowing depth is 25cm;

[0075] The second plowing will be carried out at the end of April 2018, with a plowing depth of 10 cm; during the plowing process, add 2500kg / mu superphosphate, 3000kg / mu farmyard manure, 20kg / mu N-P-K ternary compound ...

Abstract

The invention provides an ecological efficient planting method for chenopodium quinoa in saline-alkaline land. The methods of performing soil replacement to reduce alkali, performing plowing multipletimes, applying a soil improver which is superphosphate, applying an organic fertilizer, covering soil with plant ash or straw to increase temperature and preserve soil moisture, applying an acid fertilizer to neutralize salt and alkali and the like are adopted to improve the soil. Hydrogen peroxide or potassium permanganate is used for soaking chenopodium quinoa seeds to improve the salt resistance of crops. Ridging and dense planting and shallow seeding are adopted to make single plants uniform and plump. In the growing period of chenopodium quinoa, a phosphate fertilizer and a micronutrientfertilizer are sprayed to leaf surfaces to promote flowering, fruiting and grain filling and accelerate ripening of chenopodium quinoa, high-temperature periods and rainy seasons are avoided to prevent ears from sprouting, and thiram is sprayed in the grain filling period to prevent seeds from mildewing and brides from eating the seeds.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and relates to an ecologically efficient cultivation method for quinoa, in particular to a method for cultivation and cultivation of quinoa in saline-alkali land. Background technique [0002] In recent years, the problem of land salinization has become increasingly serious, and has become a worldwide problem of common concern at home and abroad. It has become an important reason for restricting agricultural development, and the improvement of saline-alkali land is imminent. my country is one of the countries with a large area of ​​coastal saline soil in the world, and it is also an important reserve land resource to be researched, developed and utilized in our country. Among them, the improvement of saline-alkali land in the Yellow River Delta is a difficult task. At present, the content of organic matter in the saline-alkali soil of the Yellow River Delta is relatively low, and the soil nutrien...
