Embodiment 1

[0032] Problem: high nitrogen plots, and due to excessive urea base application (base application pure N is 17.4kg / 667m 2 ), more yellow leaves were found at the rising stage of wheat, the root system was shallow, and the root system NH 4 + The -N content was 30.22 μg / g fresh weight.

[0033] Solution:

[0034] 1. Soil use

[0035] Soil furrow application: Potassium nitrate 6kg / 667m 2 , potassium silicate 8kg / 667m 2 , calcium silicate 6kg / 667m 2 ; Immediately irrigate.

[0036] 2. Foliar spraying

[0037] 2.2 preparation preparation

[0038] 2.2.1 Mother liquor preparation:

[0039] JA mother liquor: Dissolve jasmonic acid (JA) in dimethyl sulfoxide at a ratio of 1:1 (mg:mL), and store at low temperature;

[0040] IAA stock solution: Dissolve auxin (IAA) in dimethyl sulfoxide at a ratio of 0.175:1 (mg:mL), and store at low temperature.

[0041] 2.2.2 Spray before flowering

[0042] Raise Wheat NH 4 + Assimilation and Kuqiang's foliar spray preparation (1L) consis...

Embodiment 2

[0053] Problem: In high-fertilization plots, excessive application of urea in the early stage of wheat (basal application of pure N before wheat sowing is 16.0kg / 667m 2 ; Topdressing urea during the rising period of wheat, equivalent to pure N 11.5kg / 667m 2 ), the plant NH appeared before flowering 4 + Hyperactivity Symptoms, NH 4 + The -N content was 31.54 μg / g fresh weight.

[0054] Solution: Spray the preparation in the following way.

[0055] 1. Mother liquor preparation

[0056] JA mother liquor: dissolve jasmonic acid in dimethyl sulfoxide at a ratio of 1:1 (mg:mL), and store at low temperature;

[0057] IAA stock solution: Dissolve auxin (IAA) in dimethyl sulfoxide at 0.175:1 (mg:mL).

[0058] 2. Spray before flowering

[0059] Boost Wheat NH 4 + The foliar spray preparation (1L) for assimilating and improving the sink strength is composed of the following components: 25g of potassium nitrate, 25g of potassium silicate, 6g of calcium silicate, and 0.2mL of JA ...

Abstract

The invention discloses a method for promoting wheat NH 4 + Methods and chemicals for assimilating and increasing grain yield. The present invention is aimed at the urea or NH 4 + ‑Excessive application of N fertilizer, NH appeared in different periods of wheat 4 + Symptoms of excessive content, different chemical agents are applied in different periods (potassium nitrate, potassium silicate and calcium silicate applied on the soil surface or furrow before jointing of wheat; sprayed with potassium nitrate, silicon Potassium nitrate and JA mother liquor preparation; Spray the preparation containing potassium nitrate, potassium silicate, calcium silicate and JA mother liquor before flowering. Preparation B: Spray the preparation containing potassium nitrate, JA mother liquor and IAA mother liquor at the initial stage of grouting) to promote wheat NH 4 + Assimilation, and then converted into protein and promote the transfer of vegetative organs in wheat grain filling stage, increase grain yield, and can play an anti-lodging effect to overcome NH 4 + A series of problems caused by excessive content.

Description

technical field [0001] The invention belongs to the regulation and control of cereal crop NH 4 + Assimilation technology field, especially related to a kind of promoting wheat NH 4 + A method and a chemical preparation for converting into protein and promoting the translocation of vegetative organs in wheat grain filling stage and improving grain yield. Background technique [0002] Wheat is the most important food crop in the world. In my country, the status of wheat is second only to rice. Nitrogen is one of the essential nutrient elements for plant growth and development. It plays an extremely important role in the process of plant growth and development. It is the main component of proteins and nucleotides, and an important component of chlorophyll, vitamins, alkaloids and certain hormones. Part; the above components participate in many important metabolic processes in plants. Plant roots absorb nitrogen mainly as NH 4 + and NO 3 - dominated, however most plant...
