Description

Sustained-release sugarcane antibacterial pesticide-fertilizer granules and preparation method and application thereof
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a sustained and controlled release sugarcane bacteriostatic medicinal fertilizer granule as well as a preparation method and application thereof.
Background
Sugarcane yellow spot disease, also known as sugarcane yellow spot disease and brown spot disease. The sugarcane leaves are mainly damaged, but the heart leaves which are not unfolded and the first and second leaves which are just unfolded rarely attack the sugarcane leaves. The leaf apex of tender sugarcane leaves appears round or elliptical yellow scattered small spots, and the spots gradually fuse into large spots with the diameter of 2 cm when the disease condition spreads, and the color changes from yellow to red, so the sugarcane leaf is also called brown spot. The surface of the old lesion usually has a light gray mildew layer (conidiophores, conidia), with the back of the lesion being the most. On the same sugarcane, the basal leaves of the sugarcane are attacked and become red and dry, and the yellow spots and the red spots coexist in the middle leaves.
Sugarcane rust is an important disease caused by Puccinia nigricans or Trigonella tertiolecta and occurring on sugarcane. The disease mainly occurs on the leaf, the diseased leaf initially presents a small yellowish spot, and then the diseased spot is elongated in parallel along the veins, and the color changes from orange brown to dark brown. The occurrence of the sugarcane is reported in a plurality of sugarcane planting countries and regions in the world, each sugarcane region in China is scattered, and in recent years, the local occurrence of sugarcane regions in Guangdong, Guangxi and Yunnan is serious and tends to spread.
Terpene alcohol is an extract of Melaleuca alternifolia, a novel botanical fungicide, and has biological stimulant function. The biological bactericide has the functions of protection and treatment, and can prevent and treat plant diseases caused by various fungi and bacteria. The molecular formula of the tebuconazole is C 16 H 22 ClN 3 O is a triazole bactericidal pesticide with high efficiency, broad spectrum and systemic property, has three functions of protection, treatment and eradication, and has wide bactericidal spectrum and long lasting period. Tebuconazole can inhibit the demethylation of ergosterol on a fungal cell membrane, so that germs cannot form the cell membrane, thereby killing the germs. The product can be used for preventing and treating sugarcane fungal diseases such as sugarcane rust, sugarcane brown streak, and sugarcane yellow spot, and has the advantages of good prevention effect, lodging resistance, and obvious yield increasing effect.
Sugarcane is a main raw material for sugar production in China and is also an important raw material for light industry, chemical industry and energy. Therefore, the development of sugarcane production has important status and effect on improving people's life, promoting the development of agriculture and related industries, and even on the development of the whole national economy. The sugarcane has long growth period, tall and big plants and high yield, and the fertilizing amount is one of the main factors for determining the yield. Because the fertilizer demand of the sugarcane is large, the fertilizer occupies a large proportion in the production cost of the sugarcane, so that the fertilizer application technology is correctly mastered, the fertilizer is timely and appropriate, the requirement of the sugarcane on the fertilizer is met to the maximum extent, and the method has important significance. According to the fertilizer requirement characteristics of the sugarcane in different growth periods, the conventional fertilizer application principle is as follows: the base fertilizer is applied again, and the topdressing is carried out timely and periodically. If only top dressing is applied, but not base fertilizer, the sugarcane is easy to grow: heavy head and light foot, thick upper part and thin lower part, easy to fall down. Otherwise, only base fertilizer is applied, and no additional fertilizer is applied, so that the aftereffect is insufficient, and the sugarcane tail is formed, thereby influencing the yield. After the fertilizer is subjected to coating treatment, the nutrient release rate of the fertilizer is slower than that of a quick-acting fertilizer or a fertilizer without a coating, the nutrient duration is long, the nutrient can be effectively prevented from being absorbed by crops too late after the nutrients are quickly released at one time, and nutrient loss and waste caused by rainwater, scouring or microbial decomposition can be effectively avoided, the frequency of topdressing the sugarcane can be reduced, and the fertilizing cost can be reduced.
Therefore, the slow-release and controlled-release coating technology is combined with the bactericide and the fertilizer to form the slow-release and controlled-release antibacterial medicinal fertilizer, the requirements of sugarcane planting management can be effectively met, and diseases can be prevented while fertilization is carried out. Firstly, the fertilizer utilization rate can be effectively improved, the fertilizer application cost can be reduced, and secondly, the diseases of the sugarcane can be effectively prevented. In addition, the organic fertilizer layer in the pesticide fertilizer particles can promote the organic matters of soil, promote the utilization of waste and improve the rural environment.

Figure BDA0003622451070000151
As can be seen from Table 3, the medicinal fertilizer of the application has the advantages that the plant height is not as high as that of a common fertilizer in three months, but the action effect is obvious along with the prolonging of time. The organic fertilizer and the drug fertilizer core are separated by the coating material (treatment one), and compared with the method of simply mixing and only coating one layer (treatment two), the method can more effectively avoid the influence of the drug fertilizer on the microbial activity in the fruit and vegetable waste and the sugarcane leaf fermentation product, and is more favorable for the growth of the sugarcane.
Example 12
The sample was prepared as in example 7. The application amount is calculated according to 16 kg/mu, and the effects of two fertilizers on soil improvement are compared by taking a common fertilizer (not coated, directly mixed and granulated) containing the same nutrient content and the same amount of sugarcane leaves and defective fruit and vegetable fermentations as a reference. Each treatment is repeated for 3 times, soil samples are taken 60 days after topdressing, and the pH value, the EC value and the soil granules of the soil are detected. Wherein the soil particle size is measured to identify the soil texture. The dividing method of the soil texture refers to the classification standard of soil made in the United states: 1000-2000 μm is extra coarse sand; 500-1000 μm coarse sand; 250-500 mu m is medium sand; 100-250 is fine sand; 50-100 μm is superfine sand; 2-50 μm is powder; less than 2 μm is a sticky particle.
TABLE 4 Effect of different fertiliser treatments on the physicochemical Properties of the soil
Figure BDA0003622451070000152
