Embodiment 1

[0018] A salt-resistant seedling-preserving agent that promotes the safe and effective growth of cotton in saline-alkali soil. The weight percentage of its composition is: 0.00033% sodium nitrophenolate, 0.001% fresh amine fat, 0.5% potassium nitrate, 0.0006% boric acid, 0.0002% zinc sulfate, 0.0001 % Copper sulfate, 0.0001% manganese sulfate, the balance is clean water.

[0019] Precisely weighed with a one-ten thousand balance: 0.05g sodium nitrophenolate, 0.15g fresh amine fat, 75g potassium nitrate, 0.09g boric acid, 0.03g zinc sulfate, 0.015g copper sulfate, 0.015g manganese sulfate, dissolved in 15L ( 1 bucket of knapsack sprayer) clean water.

Embodiment 2

[0021] A salt-resistant and seedling-preserving agent that promotes the safe and effective growth of cotton in saline-alkali soil. Its composition by weight percentage is: 0.0005% sodium nitrophenolate, 0.001% fresh amine fat, 0.3% potassium nitrate, 0.0006% boric acid, 0.0002% zinc sulfate, 0.0001 % Copper sulfate, 0.0001% manganese sulfate, and the balance is clean water.

[0022] Precisely weighed with a one-ten thousand balance: 0.075g sodium nitrophenolate, 0.15g fresh amine fat, 45g potassium nitrate, 0.09g boric acid, 0.03g zinc sulfate, 0.015g copper sulfate, 0.015g manganese sulfate, dissolved in 15L ( 1 bucket of knapsack sprayer) clean water.

Embodiment 3

[0023] Example 3 (Effects of field test of anti-salt seedling protection agent)

[0024] The field test site was located in the original rice and wheat seed field (38°41′N, 120°35′E), Dafeng City, Jiangsu Province. It belongs to the moderate coastal beach saline-alkali land. The average salt content of the cultivated layer (0-20cm) soil is 0.40% , Organic matter content is 0.73%, alkaline hydrolysis nitrogen content is 56mg / kg, effective phosphorus content is 9.3mg / kg, and available potassium is 108.2mg / kg. The tested variety was Lu Mianyan 37 (National Approved Cotton 2008006), provided by Shandong Cotton Research Center. The formulations of Examples 1 and 2 were treated with anti-salt seedling protection agents, and the same amount of water was used as a control, and the liquid amount was 15L / mu. The knapsack sprayer was used to spray evenly on the front and back of the seedling leaves. The test is repeated 3 times, the plot area is 37m 2 , Planting with equal row spacing (76c...

Abstract

The invention discloses an anti-salt seedling-keeping agent for accelerating safe and effective growth of saline-alkali soil cotton at a seedling stage, belonging to the technical field of agricultural production. The anti-salt seedling-keeping agent is mainly composed of the following components: compound sodium nitrophenolate, diethyl aminoethyl hexanoate, potassium nitrate, boric acid, zinc sulfate, copper sulfate, manganese sulfate and clean water. The anti-salt seedling-keeping agent is combined with the effects of a plant growth regulating substance and a mineral element to be adjusted and controlled in the two aspects of plant hormone physiology and mineral nutrition so as to effectively enhance the root activity and the over-ground part growth vigor of seedlings of the saline-alkali soil cotton and obviously improve the salt and alkali endurance capacity; the anti-salt seedling-keeping agent has the effects of accelerating the saline-alkali soil cotton to grow at the seedling stage and obtaining ordered and strong seedlings. The main components of the anti-salt seedling-keeping agent are easily dissolved in water; the preparation process is simple and convenient and is easy to master and operate by farmers, so that the anti-salt seedling-keeping agent is particularly suitable for spraying leaf surfaces of the saline-alkali soil cotton at the seedling stage or irrigating roots.

Description

1. Technical Field [0001] The invention relates to a salt-resistant seedling protection agent for promoting safe and effective growth of cotton seedlings in saline soil, and belongs to the technical field of agricultural production. 2. Background technology [0002] There are 950 million hectares of saline-alkali land in the world, which is a precious land resource for mankind. However, saline-alkali land is not suitable for the growth of crops, and the development of agricultural production on saline-alkali land is a worldwide problem. A large amount of salinized and alkalized soil is distributed in the inland and coastal areas of northern my country, which seriously restricts the development of agricultural production. Cotton is a pioneer crop in saline-alkali land. The use of the salt-tolerant characteristics of cotton to develop inland saline-alkali land and cotton planting along beaches can not only enable the effective development and utilization of saline-alkali land, but...
