Discussion on the application of potato balanced fertilization technology
I just talked about corn crops just above, and this article will discuss the fourth largest food crop potato in rice, wheat and corn. In the new era, in order to meet the actual development needs of the society, we should pay attention to the application of potato balanced fertilization technology, improve the quality and yield of potatoes, and promote the further development of the potato economy. 1 Basic principles of potato fertilization In the seedling stage, the amount of fertilizer absorbed by the potato is relatively small. When the flowering stage is reached, the amount of fertilizer will increase greatly. When the potato is in the early stage, the amount of fertilizer will reach the peak. After that, the amount of fertilizer will drop rapidly. The amount of fertilizer required in the first half of the period accounted for more than 70% of the total potato fertilizer intake. When fertilizing, it should be based on the application of organic fertilizers, supplemented by chemical fertilizers, with basic fertilizers and topdressing as the auxiliary, with a large number of elements and supplemented by trace elements. In order to achieve the balance and standardization of fertilization, it should be promoted, controlled, and protected. In the early stage, N and P should be applied to promote the potato to achieve early growth and quick branching, and more branches can be achieved. Effect. In the middle of the potato growth, there is no need to apply fertilizer. The purpose is to control the potato stems and leaves not to grow wild, to ensure that the potato underground tubers can be scientifically formed and gradually expand. At the later stage, foliar spray should be carried out, so that the leaf color of the potato should not be prematurely yellowed, thus accelerating the photosynthesis rate of the leaves, and then providing sufficient nutrients for the growth of the potatoes. 2 Application of potato balanced fertilization technology In the new era, when planting potatoes, fertilization technology has attracted much attention, which directly affects the actual nutrient composition of the potato, and can provide corresponding fertilization services according to the different growth stages of the potato. In this study, the balanced fertilization technology was fully utilized, mainly to gradually shift the traditional blind fertilization to quantitative fertilization. From the previous single fertilization to the organic fertilizer, it was also combined with some chemical fertilizers. To achieve the purpose of increasing crop yield, reducing fertilizer, improving quality, increasing income and balancing soil nutrients. The following is a detailed analysis of specific balanced fertilization techniques. 2.1 attach importance to the application of base fertilizer In terms of dosage, the base fertilizer usually accounts for 70% of the total fertilization amount, and the base fertilizer applied is mainly based on the fermented farmyard manure, and it is also combined with the application of certain N, P, and K fertilizers. When fertilizing, if the plot 667m2 produces 2000.0kg potato, 3200kg of decomposed organic fertilizer, 45kg of superphosphate, 18kg of urea and 12kg of potassium sulfate should be applied. If the yield of the plot is higher, the amount of fertilizer should be increased. When fertilizing, the fertilizer should be applied to the 4.5cm position of the potato seed potato to avoid burning. When the base fertilizer is applied in the early stage, the organic fertilizer should be applied on the cultivated ground, and when the fertilizer is applied, the concentrated ditch should be carried out before planting, usually at a depth of about 15.0 cm. 2.2 Scientific application of fertilizer When planting, a certain amount of seed fertilizer should be applied, and the ditch method should be applied to apply 7kg/667m2 of diammonium phosphate. The depth of application of the seed fertilizer should be about 5cm deeper than the seed. Seeds and seed fertilizers should be separated and treated in time. If they cannot be separated, it is forbidden to carry seed fertilizer. 2.3 early application of top dressing In the seedling stage of potato, the best topdressing should be applied in time, and the N fertilizer should be applied. According to the actual situation of cultivating soil, the amount of urea applied is 4kg/667m2; after the bud stage, the urea is applied 7kg/667m2. 8kg/667m2. The distance from the root of the plant should be ditched at a distance of 4cm. The method of applying the ditch or applying the hole should be adopted. After the fertilization is completed, the soil should be covered tightly to achieve the purpose of promoting early seedling growth. After the flowering of the potato, there is no need to top dress in the rhizosphere, especially the N fertilizer. 2.4 Do a good job in foliar topdressing During the formation and expansion period of potato tubers, topdressing should be carried out on the leaf surface, mainly by spraying Shibao organic water-soluble fertilizer for spraying operation. The spraying frequency is 3 times, aiming at achieving the balance of nutrition and preventing the occurrence of later stages. The problem of yellowing of the leaves. When performing foliar topdressing, ensure that 35m L of sprayed Shibao to 50kg of water per 667m2 is used for continuous spraying, with an interval of 8~10d. 3 Conclusion In order to improve the economic level of potato planting and increase the yield of potato planting, it will seek higher economic profits for growers. If you want to meet this goal, you should pay attention to the scientific application of balanced fertilization technology, set a scientific fertilization plan and fertilization program, and strictly control the fertilization parameters to provide the nutrients needed for potato growth. The application of potato balanced fertilization technology should be applied to the application of base fertilizer, emphasizing the early application of topdressing and foliar topdressing treatment, thereby increasing the yield and quality of the potato, in order to provide farmers with higher economic benefits. The above is the main content of the application of potato balanced fertilization technology today. Farmers who have planted potatoes can refer to this article and improve their technical experience!
