Embodiment 1

[0021] A kind of method that uses soil conditioning agent to improve Chinese cabbage yield, comprises the following steps:

[0022] S1. Cultivate Chinese cabbage seedlings using 72-hole plug trays (substrate is perlite), and transplant and plant them in non-woven bags when 3 to 4 true leaves emerge from the Chinese cabbage seedlings, with 8 to 10 plants in each bag;

[0023] S2. Then apply ternary compound fertilizer N-P in each cultivation bag 2 o 5 -K 2 O: 15-15-15, wherein 60% of the chemical fertilizer is base fertilizer, and 40% of the chemical fertilizer is applied in the form of topdressing. The dosage accounts for 30%, 35%, and 35% of the total topdressing fertilizer respectively;

[0024] S3. After transplanting, the soil conditioner was diluted 500 times with water, and 100-300 mL of the soil conditioner dilution was evenly sprayed on the soil surface on the 20th to 34th day after sowing Chinese cabbage, thereby increasing the yield of Chinese cabbage.

Embodiment 2

[0026] A kind of method that uses soil conditioning agent to improve Chinese cabbage yield, comprises the following steps:

[0027] S1. Cultivate Chinese cabbage seedlings using 72-hole plug trays (substrate is perlite), and transplant and plant them in non-woven bags when 3 to 4 true leaves emerge from the Chinese cabbage seedlings, with 8 to 10 plants in each bag;

[0028] S2. Then apply ternary compound fertilizer N-P in each cultivation bag 2 o 5 -K 2 O: 15-15-15, wherein 60% of the chemical fertilizer is base fertilizer, and 40% of the chemical fertilizer is applied in the form of topdressing. The dosage accounts for 30%, 35%, and 35% of the total topdressing fertilizer respectively;

[0029] S3. Dilute the soil conditioner 1000 times with water after transplanting, and spray 100-300mL of the soil conditioner dilution evenly on the soil surface on the 20th to 34th day after sowing Chinese cabbage, thereby increasing the yield of Chinese cabbage.

Embodiment 3

[0031] A kind of method that uses soil conditioning agent to improve Chinese cabbage yield, comprises the following steps:

[0032] S1. Cultivate Chinese cabbage seedlings using 72-hole plug trays (substrate is perlite), and transplant and plant them in non-woven bags when 3 to 4 true leaves emerge from the Chinese cabbage seedlings, with 8 to 10 plants in each bag;

[0033] S2. Then apply ternary compound fertilizer N-P in each cultivation bag 2 o 5 -K 2 O: 15-15-15, wherein 60% of the chemical fertilizer is base fertilizer, and 40% of the chemical fertilizer is applied in the form of topdressing. The dosage accounts for 30%, 35%, and 35% of the total topdressing fertilizer respectively;

[0034] S3. Dilute the soil conditioner 1500 times with water after transplanting, and evenly spray 100-300mL of the soil conditioner dilution on the soil surface on the 20th to 34th day after sowing Chinese cabbage, thereby increasing the yield of Chinese cabbage.

Abstract

The invention belongs to the technical field of efficient and sustainable production in modern agriculture, and discloses a method for increasing yield of Chinese flowering cabbages by using a soil conditioner. The method comprises the following steps: cultivating Chinese flowering cabbage seedlings by using 72-hole trays and transplanting and planting the Chinese flowering cabbage seedlings into non-woven bags with 8-10 plants in each bag when the Chinese flowering cabbage seedlings have 3-4 true leaves; applying a three-element compound fertilizer N-P2O5-K2O:15-15-15 is applied to each cultivation bag and applying topdressing in three times in a seedling growing period, a leaf growing period and a forming period of Chinese flowering cabbages with the amount of the topdressing accounting for 25-35%, 30-40% and 30-40% of the total topdressing amount each time; and after transplanting, diluting a soil conditioner by 500-1500 times with clean water, such that yield of Chinese flowering cabbages is increased. Under a cultivation condition that the diluted soil conditioner is sprayed and the chemical fertilizer is applied, the yield and quality of Chinese flowering cabbages are improved, comprehensive characters of the soil are obviously improved, and continuous cropping obstacles are relieved.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency and sustainable production of modern agriculture, and more specifically relates to a method for increasing the yield of Chinese cabbage by using a soil conditioner. Background technique [0002] In recent years, protected horticulture has developed rapidly in my country, and the cultivation area of ​​protected vegetables has increased year by year. It has become an important pillar industry to increase farmers' income and drive urban and rural development. However, facility vegetable production is characterized by high intensification, high multiple cropping index, single cultivated species, and relatively closed nature. Long-term planting causes serious obstacles to continuous cropping, resulting in reduced yield, poor quality, and poor growth status. [0003] Cabbage heart (Brassica campestris L.ssp. Chinensis var. Utilis Tsen et Lee) is a specialty vegetable in South China. It has uniqu...
