Problems solved by technology

Due to the difficulty in planting Shanghai Green, it is difficult to achieve economic value by large-scale planting: 1. It can only be planted in loam or sandy loam, and cannot grow in saline soil; 2. It needs a lot of water to grow, and its growth is stunted in drought; 3. At the same time, it is also afraid of stagnant water, which is easy to die when it is stagnant, causing diseases and resulting in low yield
[0003] The Chinese invention patent with the publication number CN 105152734A discloses a special high-temperature-resistant foliar fertilizer for Shanghai Green and its application method, which is only suitable for high-temperature resistance, and cannot solve the problems of its resistance to drought, water accumulation, and salinity, which are not suitable for soil adversity. question

Embodiment 1

[0046] Take by weighing 1.5 parts of chitosan oligosaccharides, 3 parts of urea, 2.5 parts of potassium chloride, 5 parts of ammonium nitrate, 1 part of sodium carbonate, 0.12 parts of salicylic acid, 0.5 parts of dextran and mix to obtain the anti-stress foliar fertilizer according to Table 1 .

[0047] The test was carried out from August to October 2018. The test variety was Shanghai Green. The experimental conditions were set to plant in dry soil / waterlogged soil / saline soil. At the same time, water was sprayed on the leaves in the corresponding soil as a control treatment:

[0048] Mix the anti-stress foliar fertilizer and water evenly at a mass ratio of 1:130, and spray it on the leaves when Shanghai Qing has 2 leaves and 4 leaves;

[0049] Mix the anti-stress foliar fertilizer and water evenly at a mass ratio of 1:65, and spray it on the leaves when Shanghai Green has 6 leaves and 8 leaves.

Embodiment 2

[0051] Take by weighing 0.5 part of chitosan oligosaccharide, 2 parts of urea, 2 parts of potassium chloride, 3 parts of ammonium nitrate, 0.5 part of sodium carbonate, 0.05 part of salicylic acid, 0.2 part of dextran and mix to obtain the anti-stress foliar fertilizer .

[0052] The test was carried out from August to October 2018. The test variety was Shanghai Qing, and the experimental conditions were set to plant in dry soil / waterlogged soil / saline soil, and a control treatment of spraying water on the leaves was set:

[0053] Mix the anti-stress foliar fertilizer and water evenly at a mass ratio of 1:100, and spray it on the leaves when Shanghai Qing has 2 leaves and 4 leaves;

[0054] Mix the anti-stress foliar fertilizer and water evenly at a mass ratio of 1:50, and spray it on the leaves when Shanghai Green has 6 leaves and 8 leaves.

Embodiment 3

[0056] Take by weighing 2 parts of chitosan oligosaccharide, 5 parts of urea, 5 parts of potassium chloride, 7 parts of ammonium nitrate, 3 parts of sodium carbonate, 0.2 part of salicylic acid, 1.2 parts of dextran and mix to obtain the anti-stress foliar fertilizer according to Table 1 .

[0057] The test was carried out from August to October 2018. The test variety was Shanghai Qing, and the experimental conditions were set to plant in dry soil / waterlogged soil / saline soil, and a control treatment of spraying water on the leaves was set:

[0058] Mix the anti-stress foliar fertilizer and water evenly at a mass ratio of 1:150, and spray it on the leaves when Shanghai Qing has 2 leaves and 4 leaves;

[0059] Mix the anti-stress foliar fertilizer and water evenly at a mass ratio of 1:80, and spray it on the leaves when Shanghai Green has 6 leaves and 8 leaves.

Abstract

The invention discloses a special anti-stress foliar fertilizer for Brassica chinensis L., and a using method thereof. The special anti-stress foliar fertilizer for Brassica chinensis L. comprises, bymass, 0.5-2.0 parts of chitooligosaccharide, 2-5 parts of urea, 2-5 parts of potassium chloride, 3-7 parts of ammonium nitrate, 0.5-3 parts of sodium carbonate, 0.05-0.2 part of salicylic acid and 0.2-1.2 parts of glucosan. The anti-stress foliar fertilizer can significantly improve the resistance of the Brassica chinensis L. to drought, ponding and saline soil, and significantly improves the plant growth, the protein content and the yield.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a special stress-resistant foliar fertilizer for Shanghai green and its application method. Background technique [0002] Shanghai Qing, a kind of Chinese cabbage, with few leaves and many stems, oval-shaped leaves, thick petioles, turquoise green, waist-shaped plant, beautiful and neat, fine fibers, sweet taste and good taste, it is one of the main cultivated vegetables in most parts of southern my country . However, Shanghai Qingxing likes a cool and cool climate, and the cultivation soil is easy to be loamy or sandy loam, with good drainage and sunshine. Due to the difficulty in planting Shanghai Green, it is difficult to achieve economic value by large-scale planting: 1. It can only be planted in loam or sandy loam, and cannot grow in saline soil; 2. It needs a lot of water to grow, and its growth is stunted in drought; 3. At the same time, it is also afraid of stagnant water. W...
