Description

Technical Field

[0001] The invention relates to the technical field of fertilizers, and in particular to a method for preparing and applying a sugarcane package fertilizer. Background Art

[0002] At present, the pesticide fertilizer industry is developing rapidly. The advantages of pesticide fertilizer are: balanced fertilization and complete nutrients; combination of pesticide fertilizer and mutual synergy, improved safety and reduced losses; easy operation, labor-saving and cost-saving, and can also increase production and income. Relevant research shows that the mixed application of pesticide fertilizer generally increases the efficacy of the drug by more than 10%, and the fertilizer efficiency can also increase by 6% to 8%, with better pest control effect and better yield.

[0003] In order to meet the nutrient requirements of crops in different growth stages, fertilizer combinations, namely package fertilizers, have become a hot topic in the fertilizer industry. When designing package fertilizers, the soil nutrient content and the nutrient requirements of crops at different stages are taken into account. Through scientific matching and precise formulation, crop yields are increased and quality is improved. At present, package fertilizers have been used in crops such as tomatoes, rice, ginger, and apples, and have achieved good results. However, research on package fertilizers for sugarcane is relatively scarce.

[0004] At present, its green and high-quality development has the following problems: The first is the problem of fertilization, which is specifically manifested in excessive fertilizer input, low fertilizer utilization rate, unreasonable fertilization structure, etc. At different growth stages of sugarcane, the demand for nutrients shows a trend of "less at the two ends and more in the middle". Among them, the demand for nutrients is the highest during the elongation period. However, the existing fertilization plan tends to apply nitrogen fertilizer, less potassium fertilizer and organic fertilizer, which fails to match the nutrient requirements of sugarcane at different growth stages, resulting in the failure to fully realize the potential production capacity of sugarcane.

[0005] The second is the problem of pests and diseases. There are many types of sugarcane pests and diseases, which run through the entire growth cycle. Common pests and diseases include borers, smut, thrips, aphids, etc. The pests and diseases faced at different growth stages are different. At the same time, the occurrence of one pest and disease may lead to the occurrence of another pest and disease. According to statistics, pest and disease problems can cause a loss of more than 46% in sugarcane yield and reduce the quality of sugarcane. However, the existing pest and disease prevention and control methods blindly use drugs and large amounts of drugs, and fail to apply the correct pesticides and fertilizers for pests and diseases.

[0006] Pesticide fertilizers can effectively achieve nutrient supply and disease control, and are integrated and convenient to apply. However, the pesticide fertilizer products commonly used in sugarcane production are numerous, with similar effective ingredients, a single goal of controlling pests and diseases, and cannot meet the nutrient needs of sugarcane growth, resulting in the mismatch between the application period and the occurrence period of pests and diseases, and the beneficial insects are easily killed, which is counterproductive, forming a vicious cycle of "heavy pests and more pesticides" when applying pesticides.

[0007] In summary, the sugarcane industry currently lacks package fertilizers that match the nutrient requirements of different periods, and package fertilizers that match the pests and diseases of different periods. This field is in urgent need of a package fertilizer that can meet the nutrient requirements of sugarcane at different growth stages and the needs of pest and disease control, and ultimately achieve the goal of increasing production and sugar.

The rest of the field management links were the same.

[0076] 7. Test results

[0077] (1) Agronomic traits

[0078] The population density was calculated 120, 150, and 180 days after planting, and the test results are shown in Table 3. The plant height was calculated 150, 180, and 210 days after planting, and the test results are shown in Table 3. Figure 1 (Xingbin District), Figure 4 (Wuming District) as shown.

[0079] Table 3

[0080] Note: Different lowercase letters represent significant differences in the indicators among different treatments (P<0.05).

[0081] The results of population density showed that the population density of sugarcane gradually decreased with the advancement of the growth period. There was no significant difference in population density 120 days after planting. As time increased to 180 days, there was a significant difference between package fertilizer, package fertilizer and conventional fertilization. From the comparison of treatment one and treatment two in the Xingbin District test site, it can be concluded that package fertilizer increased 522 plants / mu through targeted fertilization. From the comparison of treatment two, treatment three and treatment four in the Wuming District test site, it can be concluded that package fertilizer increased 300 plants / mu and 1050 plants / mu through targeted application of pesticides. The best performing groups in Wuming District and Xingbin District were both treatment four, which had 1350 plants / mu and 2087 plants / mu more than conventional fertilization in treatment one.

[0082] The results of plant height showed that the growth rate of sugarcane in Wuming District was high in the early stage of elongation, with the fastest being 3.07 cm / day in treatment 4, and then slowed down as the growth period progressed, with the fastest being 1.04 cm / day in treatment 4. There was no significant difference in plant height at 150 days, but significant differences began to appear from 180 days. By comparing treatments 3 and 4 with treatments 1 and 2, it was concluded that package fertilizers could increase plant height by reducing pests and diseases in a targeted manner. From the significant difference between treatments 1 and 2 at 210 days, it was concluded that targeted fertilization could increase plant height by 11.40 cm. Treatment 4 performed best at 210 days, with significant differences from the other groups, at 258.93 cm, an increase of 37.93 cm compared with conventional fertilization in treatment 1.

[0083] The growth rate of sugarcane in Xingbin District was relatively high in the early stage of elongation, with the fastest being 3.20 cm / day in treatment four. It then slowed down with the advancement of the growth period, with the fastest being 0.72 cm / day in treatment three. There was no significant difference in plant height at 150 days, but significant differences began to appear from 180 days. Treatments two, three, and four were significantly different from treatment one. At 210 days, treatments three, four, and two were significantly different, indicating that targeted fertilization and pesticide application can make sugarcane grow better. Treatment three performed best, with a plant height of 251.60 cm, an increase of 35.27 cm compared with conventional fertilization in treatment one.

[0084] (2) Yield and sugar yield

[0085] The yield and sugar production were calculated 210, 225, and 240 days after planting, as shown in Table 4.

[0086] Table 4

[0087] Note: Different lowercase letters represent significant differences in the indicators among different treatments (P<0.05).

[0088] The results showed that the combination of targeted fertilization and pesticide application can increase sugarcane yield, but targeted fertilization without pesticide application cannot increase sugarcane yield. Overall, there was no significant difference. The yield of treatment 4 in Wuming District was 6347 kg / mu, an increase of 1369 kg / mu compared with treatment 1 with conventional fertilization, an increase of 27.50%. The yield of treatment 4 in Xingbin District was 6102 kg / mu, an increase of 1040 kg / mu compared with treatment 1 with conventional fertilization, an increase of 20.55%.

[0089] In terms of sugar yield, the highest sugar yield was 828 kg / mu in treatment 4 of the test site in Wuming District, which was significantly different from treatment 1 with conventional fertilization, and increased by 190 kg / mu, an increase of 29.78% compared with treatment 1. The highest sugar yield was 714 kg / mu in treatment 4 of Xingbin District, which was significantly different from treatments 1 and 2, and increased by 115 kg / mu, an increase of 19.19% compared with treatment 1 with conventional fertilization.

[0090] (3) Economic benefits

[0091] After the harvest, the cost, output value and income were calculated based on the yield, raw material price and sugarcane price, as shown in Table 5. The raw material price is the price at which Duodele purchased the raw materials, the conventional fertilization price is the market price of the fertilizer of Duodele, and the sugarcane price is 510 yuan / ton.

[0092] Table 5

[0093] According to the calculation, treatment 2 was a loss compared with treatment 1 with conventional fertilization, while treatments 3 and 4 were gains compared with treatment 1 with conventional fertilization. Treatment 4 performed best in economic benefits. The income per mu of test point in Wuming District was 3,237 yuan, an increase of 663 yuan compared with treatment 1 with conventional fertilization, a growth rate of 19.22%. The income per mu in Xingbin District was 3,112 yuan, an increase of 496 yuan compared with treatment 1 with conventional fertilization, a growth rate of 26.11%.

[0094] The above test results show that the best performance in the package of pesticide-fertilizer is treatment four. In Wuming District, the sugarcane yield per mu is 6347 kg, an increase of 1369 kg compared with conventional fertilizer, the sugar yield is 828 kg, an increase of 190 kg compared with conventional fertilizer, and the output value is 3237 yuan, an increase of 663 yuan compared with conventional fertilizer; the sugarcane yield per mu in Xingbin District is 6102 kg, an increase of 1040 kg compared with conventional fertilizer, the sugar yield is 714 kg, an increase of 115 kg compared with conventional fertilizer, and the output value is 3112 yuan, an increase of 496 yuan compared with conventional fertilizer.

[0095] In summary, the sugarcane package fertilizer of the present invention can provide a more scientific nutrient ratio and input timing through targeted fertilization, match the demand for different nutrients in different growth periods of sugarcane, so that sugarcane can stably obtain the nutrients it urgently needs at different growth stages, and can provide additional trace elements, promote sugarcane production and sugar increase, improve sugarcane production, and further, the sugarcane package fertilizer can be applied for pests and diseases, matching the different pests and diseases faced by sugarcane in different growth periods, thiamethoxam can prevent the frequent borers in the whole growth period, inhibit smut, and thiamethoxam can prevent and control the frequent cotton aphids in the elongation period and maturity period, bringing practical economic benefits. In addition, the fertilizer and pesticide application amount of the sugarcane package fertilizer of the present invention is reasonable, the effect of increasing production and increasing sugar is obvious, fertilization and application are carried out simultaneously, reducing farmers' labor time and improving environmental protection.
