Embodiment 1

[0012] Example 1: Formulation

[0013] A compound regulator for preventing corn lodging and increasing production, according to the composite regulator per kilogram, comprising succinic acid (also known as succinic acid, ethylene dicarboxylic acid, 1,2-ethanedicarboxylic acid, oxalic acid, molecular formula: C 4 h 6 o 4 ): 301-400mg / kg; fenpyrosuron (also known as fenguolone, Shi Teyou, urea kinetin, KT-30, CPPU, 4PU-30, molecular formula: C 12 h 10 ClN 3 O, chemical name: 1-(2-chloro-4-pyridyl)-3'-phenylurea): 0.000031-0.00005mg / kg; Molecular formula: C 15 h 18 ClN 3 O, chemical name: E-(RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4triazol-1-yl)penta-1- En-3-ol): 20-60mg / kg; Potassium dihydrogen phosphate (molecular formula: KH 2 PO 4 ): 50000-100000mg / kg.

Embodiment 2

[0014] Embodiment 2: method of use

[0015] Method (1): Use the above-mentioned compound conditioner to dress the seeds, mix the seeds well (about 20 minutes), and then sow after drying.

[0016] Method (2): In the early stage of corn jointing (generally at the time of 5-6 leaves), use a conventional sprayer to evenly spray 30 kg of the above-mentioned compound regulator on the corn plants, depending on the degree of humidity.

[0017] You can use one of the above two usage methods according to your needs.

[0018] Application effect:

[0019] (1) The root system of corn plants is developed and the root system activity is enhanced. At the three-leaf stage, the root length increased by 5.37cm / plant compared with the control, the number of secondary roots increased by 1.67 / plant, and the fresh weight of the root increased by 0.067g / plant compared with the control; Compared with the control, the number of secondary roots increased by 6.2 per plant, the number of secondary root...

Abstract

The invention discloses a yield-increasing composite regulator for preventing corn lodging. In terms of each kilogram of the composite regulator, 0.000031-0.00005 mg succinic acid, 20-60 mg uniconazole and 50,000-100,000 mg monopotassium phosphate are included. The invention also discloses a use method of the composite regulator. By using the invention, stumpish corn seedlings, developed root system, increased root quantity and enhanced activity of the root system are realized. By using the yield-increasing composite regulator disclosed by the invention, corns have the advantages of tough stalk, reduced and thickened space between the base and a third section of the plant, reduced plant height and low ear position descending, and an obvious effect of preventing the corn lodging is achieved; The color of the corn leaf is deepened, the intensity of photosynthesis is enhanced and the accumulation and operation of dry matters in the corn plant are accelerated; The corn yield is increased in such ways that the corn yield is increased by 5.2% in contrast to a condition with no corn plant lodging and the corn yield is increased by 15.4% in contrast to a condition with corn plant lodging.

Description

technical field [0001] The invention relates to the technical field of crop regulators, in particular to a compound regulator for preventing corn lodging and increasing production and a use method thereof. Background technique [0002] Corn is an important food and fodder crop in my country, and occupies an extremely important position in the national economy. The abundance or decline of corn production has gradually become an important factor affecting the balance of food supply and demand in my country and determining the development of animal husbandry. Maize lodging is the phenomenon that the stalk changes from an upright state to an inverted one due to external factors. Lodging has always been an important factor affecting the yield and quality of corn. According to relevant statistics, lodging leads to a 15-25% reduction in corn yield. The yield loss of corn due to lodging in my country is nearly 1 million tons every year. At present, with the continuous improvement ...
