Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fertilizers, in particular to a preparation and application method of a sugarcane package fertilizer. BACKGROUND

[0002] At present, the pharmaceutical fertilizer industry is developing rapidly. The advantages of pharmaceutical fertilizers are: balanced fertilization, complete nutrients; combination of pharmaceutical fertilizers, mutual interaction, improved safety, reduced losses; simple operation, labor saving and cost saving, and also increased yield and income. Related research shows that the general drug effect of mixed application of pharmaceutical fertilizers increases by more than 10%, the fertilizer effect also increases by 6% to 8%, and there is better disease and pest control effect and better yield.

[0003] In order to meet the nutrient needs of crops at different growth stages, the combination of fertilizers, i.e. package fertilizer, has become a hot spot in the fertilizer industry. When designing the package fertilizer, the soil nutrient content and the nutrient needs of crops at different stages are considered, and through scientific matching and precise formula, the yield of crops is increased and the quality is improved. At present, package fertilizers have been applied to crops such as tomatoes, rice, ginger and apples, and good results have been achieved. However, there is a lack of research on package fertilizers for sugarcane.

[0004] At present, there are the following problems in the green and high-quality development:

[0005] First of all, the problem of fertilization, which is specifically manifested in excessive fertilizer input, low fertilizer utilization rate, and unreasonable fertilization structure. Different growth stages of sugarcane have different nutrient needs, which show a trend of "less at both ends and more in the middle". Among them, the elongation period needs the most nutrients, but the existing fertilization scheme is biased towards nitrogen fertilizer, and less potassium fertilizer and organic fertilizer are applied, which cannot match the nutrient needs of sugarcane at different growth stages, resulting in that the potential production capacity of sugarcane cannot be fully utilized.

[0006] Secondly, the problem of diseases and pests. There are many types of diseases and pests of sugarcane, and they occur throughout the growth cycle. Common types of diseases and pests include borers, smut, thrips, and aphids. Different growth stages face different diseases and pests. At the same time, the occurrence of one disease and pest may lead to the continuous occurrence of another disease and pest. According to statistics, the problem of diseases and pests can cause the yield loss of sugarcane to be more than 46% and reduce the quality of sugarcane. However, the existing prevention and control of diseases and pests is blind and uses a large amount of drugs, and cannot apply the correct pharmaceutical fertilizer according to the diseases and pests.

[0007] Pharmaceutical fertilizers can effectively realize the integration of nutrient supply and disease control, and are convenient and easy to use. However, there are many pharmaceutical fertilizer products commonly used in existing sugarcane production, the effective ingredients are similar, the target of disease and pest control is single, and the nutrient needs of sugarcane growth cannot be met, so that the application period of the drug is out of phase with the occurrence period of the disease and pest, and beneficial insects are also easily killed, which is counterproductive, resulting in a vicious cycle of "heavy pest - more drug" when applying the drug.

[0008] In summary, the sugarcane industry currently lacks comprehensive fertilizers that match nutrient requirements at different growth stages, as well as comprehensive pesticide fertilizers that address pest and disease control needs at different stages. There is an urgent need for a comprehensive pesticide fertilizer that can meet the nutrient needs and pest and disease control needs of sugarcane at different growth stages, ultimately achieving the goal of increasing yield and sugar content.

[0105] Table 3

[0106]

[0107] Note: Different lowercase letters represent significant differences (P<0.05) of each index between different treatments.

[0108] The population density results show that the population density of sugarcane gradually decreases with the advancement of the growth period. There is no significant difference in the population density 120 days after planting, while significant differences appear between the package fertilizer, package pesticide fertilizer and conventional fertilization 180 days after planting. From the comparison of treatment one and treatment two in Xingbing test site, it can be concluded that the package fertilizer improves 522 plants per mu through targeted fertilization. From the comparison of treatment two, treatment three and treatment four in Wuming test site, it can be concluded that the package pesticide fertilizer improves 300 plants per mu and 1050 plants per mu through targeted pesticide application. The best group in Wuming and Xingbing areas is treatment four, which is 1350 plants per mu and 2087 plants per mu more than treatment one, conventional fertilization.

[0109] The plant height results show that the initial growth rate of sugarcane in Wuming area is relatively high, with the fastest being 3.07 cm / day for treatment four. The growth rate slows down with the advancement of the growth period, with the fastest being 1.04 cm / day for treatment four. There is no significant difference in plant height at 150 days, and significant differences appear from 180 days. Through the comparison of treatment three and treatment four with treatment one and treatment two, it is concluded that the package pesticide fertilizer can improve plant height by targeting the reduction of pests and diseases. From the significant difference between treatment one and treatment two at 210 days, it is concluded that targeted fertilization can improve plant height by 11.40 cm. The best performance at 210 days is treatment four, which is 258.93 cm, with a significant difference from the other groups, and is 37.93 cm higher than treatment one, conventional fertilization.

[0110] The initial growth rate of sugarcane in Xingbing area is relatively high, with the fastest being 3.20 cm / day for treatment four. The growth rate slows down with the advancement of the growth period, with the fastest being 0.72 cm / day for treatment three.

At 210 days, treatment three and treatment four have significant differences with treatment two, indicating that targeted fertilization and pesticide application can make sugarcane grow better. The best performance is treatment three, with a plant height of 251.60 cm, which is 35.27 cm higher than treatment one, conventional fertilization.

[0111] (2) Yield and sugar yield

[0112] The yield and sugar yield were counted at 210, 225 and 240 days after planting, as shown in Table 4.

[0113] Table 4

[0114]

[0115] Note: Different lowercase letters represent significant differences (P<0.05) between different treatments for each index.

[0116] The results show that targeted fertilization combined with pesticide application can improve the yield of sugarcane, but targeted fertilization without pesticide application cannot improve the yield of sugarcane. Overall, there is no significant difference. The yield of treatment four in Wuming test site is 6347 kg per mu, which is 1369 kg per mu higher than that of treatment one, i.e. conventional fertilization, with an increase of 27.50%. The yield of treatment four in Xingbin area is 6102 kg per mu, which is 1040 kg per mu higher than that of treatment one, i.e. conventional fertilization, with an increase of 20.55%.

[0117] In terms of sugar yield, the sugar yield of treatment four in Wuming test site is the highest, which is 828 kg per mu, and there is a significant difference between treatment one and treatment four. The sugar yield of treatment four is 190 kg per mu higher than that of treatment one, with an increase of 29.78%. The sugar yield of treatment four in Xingbin area is the highest, which is 714 kg per mu, and there is a significant difference between treatment one and treatment two. The sugar yield of treatment four is 115 kg per mu higher than that of treatment one, with an increase of 19.19%.

[0118] (3) Economic benefits

[0119] After harvesting, the cost, output value and income were calculated according to the yield, raw material price and sugarcane price, as shown in Table 5. The raw material price is the purchase price of the raw material by the company, the price of treatment one, i.e. conventional fertilization, is the market price of pesticide and fertilizer by the company, and the sugarcane price is 510 yuan per ton.

[0120] Table 5

[0121]

[0122] According to the calculation, treatment two is a loss compared with treatment one, i.e. conventional fertilization, and treatments three and four are gains compared with treatment one. The economic benefit of treatment four is the best. The income per mu in Wuming area is 3237 yuan, which is 663 yuan higher than that of treatment one, with an increase of 19.22%. The income per mu in Xingbin area is 3112 yuan, which is 496 yuan higher than that of treatment one, with an increase of 26.11%.

[0123] The above test results show that the best performance in the package pesticide and fertilizer is treatment four. In Wuming area, the yield of sugarcane per mu is 6347 kg, which is 1369 kg higher than that of conventional fertilization. The sugar yield is 828 kg, which is 190 kg higher than that of conventional fertilization. The output value is 3237 yuan, which is 663 yuan higher than that of conventional fertilization. In Xingbin area, the yield of sugarcane per mu is 6102 kg, which is 1040 kg higher than that of conventional fertilization. The sugar yield is 714 kg, which is 115 kg higher than that of conventional fertilization. The output value is 3112 yuan, which is 496 yuan higher than that of conventional fertilization.

[0124] In summary, the sugarcane package pesticide fertilizer of the present application can provide more scientific nutrient allocation and input timing through targeted fertilization, match the different nutrient requirements of sugarcane at different growth stages, so that the sugarcane can stably obtain the nutrients it urgently needs at different growth stages, and can provide additional trace elements to promote the yield and sugar of sugarcane and improve the production of sugarcane. Further, the sugarcane package pesticide fertilizer can apply pesticides according to the diseases and pests, match the different diseases and pests problems faced by sugarcane at different growth stages, thiamethoxam can prevent and control the frequent rice pests at the whole growth period and inhibit smut, and thiamethoxam can prevent and control the frequent aphids at the elongation period and mature period, which brings real economic benefits.
