Detailed Description
The invention is further illustrated by the following examples and application examples:
example 1
A preparation method of a rice aroma-enhancing zinc fertilizer comprises the following steps:
(1) dissolving 50g of humic acid in 150ml of 0.1mol/L NaOH solution, adding 40g of zinc citrate while stirring, then treating the mixed solution for 1 hour under the condition of 25kHz by using an ultrasonic cell crusher, carrying out ultrasonic treatment in the high-purity oxygen atmosphere at the oxygen flow rate of 25ml/min, and filtering and drying after the reaction is finished to obtain the chelated zinc.
(2) Uniformly mixing 45g of chelated zinc, 30g of ammonium sulfate, 20g of monopotassium phosphate, 3g of brassinolide and 2g of indoleacetic acid, slowly adding 1L of distilled water by mass, uniformly stirring, and adjusting the pH value of the solution to 6.8 to obtain the aroma-enhanced zinc fertilizer.
The method comprises the steps of taking Yannongxiang 28 of a rice variety as a test material, uniformly sowing 80g of soaked, sterilized and pregerminated rice seeds on each straw substrate disc, performing darkening treatment for 48 hours, placing the disc in a seedling bed, normally raising seedlings for 25 days according to the habit of farmers, taking the non-applied rice aroma-increasing fertilizer as a control CK treatment, and taking the applied rice aroma-increasing fertilizer as T1. After being diluted by 50 times, the flavoring zinc fertilizer raw material solution is uniformly sprayed on a dry straw matrix disc used per mu according to the dosage of 10.0 kg/mu, and is sown after being covered with thin fine soil, and then a layer of fine soil is covered. When the rice seedlings are transplanted, sampling is carried out to determine the physical and chemical properties of the root system and the plant. The results show that after the rice aroma-increasing fertilizer is applied, the root length and the dry weight of the roots are respectively increased by 16.7 percent and 63.0 percent, the seedling height and the dry weight of the seedlings are respectively increased by 27.4 percent and 42.2 percent, the leaf area is increased by 66.2 percent, and the zinc content of the overground part is increased by 235.4 percent. The rice fragrance-increasing fertilizer is beneficial to the development of the root system and the overground part of the rice seedling raised by the rice straw substrate blanket seedling and the content of key zinc in the synthesis of fragrance substances.
