Embodiment 1

[0056] A lightly simplified high-yield cultivation method for onion in saline-alkali land, the present embodiment is carried out in Dongying, comprising the steps:

[0057] 1. Seed selection: The salt-tolerant onion hybrid Tianzheng 105 was selected, which was bred by the Vegetable Research Institute of Shandong Academy of Agricultural Sciences, and was approved by the Shandong Provincial Variety Approval Committee in 2014; the general yield per mu is more than 6000kg. Good commercial properties, golden-yellow skin, glossy, the harvested onion balls have good hardness and high storage resistance. The average sphericity index is 0.85, the pseudostem is thin, the closing is good, and the average single ball weight is 300g, showing high uniformity and commerciality.

[0058] 2. AMF bacterial fertilizer for seed dressing: Before sowing onion seeds, AMF bacterial fertilizer is used for seed dressing. The bacterial fertilizer is Rhizoglomusirregulare and Funneliformis geosporum mixe...

Embodiment 2

[0077] A lightly simplified high-yield cultivation method for onion in saline-alkali land, the present embodiment is carried out in Dongying, comprising the steps:

[0078] 1. Seed selection is the same as in Example 1.

[0079] 2. AMF bacterial fertilizer for seed dressing: Before sowing onion seeds, AMF bacterial fertilizer is used for seed dressing. The bacterial fertilizer is Rhizoglomusirregulare and Funneliformis geosporum mixed in a ratio of 1:1, and the dosage is 4g bacterial fertilizer per 100g of seed dressing.

[0080] 3. Sow seeds at the right time and cultivate strong seedlings: choose to sow on September 10, 2020; every 100m 2 The seedbed area was sown with 400g of seeds. The ratio of seedbed area to planting field area is generally 1:15.

[0081] (1) Sowing method: The sowing method is adopted. Before sowing, the seedbed should be irrigated with foot water. When the water is about to seep down, the seedbed will be scraped with a wooden board and other tools. T...

Embodiment 3

[0098] A lightly simplified high-yield cultivation method for onion in saline-alkali land, the present embodiment is carried out in Dongying, comprising the steps:

[0099] 1. Seed selection is the same as in Example 1.

[0100] 2. AMF bacterial fertilizer for seed dressing: Before sowing onion seeds, AMF bacterial fertilizer is used for seed dressing. The bacterial fertilizer is Rhizoglomusirregulare and Funneliformis geosporum mixed in a ratio of 1:1, and the dosage is 5g bacterial fertilizer per 100g of seed dressing.

[0101] 3. Sow seeds at the right time and cultivate strong seedlings: choose to sow on September 15, 2020; every 100m 2 The seedbed area is sown with 550g of seeds. The ratio of seedbed area to planting field area is generally 1:20.

[0102] (1) Sowing method: The sowing method is adopted. Before sowing, the seedbed should be irrigated with bottom water. When the water is about to seep down, the seedbed will be scraped with a wooden board and other tools. ...

Abstract

The invention relates to a simplified high-yield cultivation method for onions in saline-alkali soil, which adopts a series of technical means such as saline-alkali tolerant onion hybrid Tianzheng 105, irrigation for alkali pressing, deep ploughing for alkali breaking, additional application of organic fertilizer, plastic film mulching, AMF bacterial fertilizer seed dressing and the like in saline-alkali soil, and solves the problems of difficult seedling protection, slow development and low yield of onion cultivation in 0.3-0.5% saline-alkali soil. High yield and high quality of onions in moderate saline-alkali soil are realized. Compared with a traditional cultivation method, the cultivation method provided by the invention has the advantage that high-yield and high-quality production of onions in moderate saline-alkali soil is realized.

Description

technical field [0001] The invention relates to the technical field of onion planting, in particular to a light, simplified and high-yield cultivation method of onion in saline-alkali land. Background technique [0002] Onion, also known as onion, shallot, garlic, etc., belongs to the Amaryllidaceae Allium genus biennial herb, with hypertrophy fleshy bulbs as edible organs, has high edible and medicinal value, rich in flavonoids, dietary fiber and other nutrients It has a good adjuvant treatment effect on human cardiovascular diseases, diabetes and bronchial asthma, and also has a good preventive effect on cancer, hypertension and hyperlipidemia. It is cultivated all over my country and is an important export vegetable. [0003] Arbuscular Mycorrhizal Fungi is an important class of soil microorganisms that play important physiological and ecological functions by establishing symbionts with plant roots. Studies have shown that AM fungi induce plants to enhance disease resis...
