Rationally Using Rare Earth to Increase Raspberry Yield

The so-called rare earth is a generic term for lanthanoid elements (15 species in total) with an atomic number from 57 to 71, and 17 kinds of metallic elements such as lanthanum and meso that have similar properties. In recent years, China has adopted "rare earth" as a "different fertilizer" and has achieved remarkable results in its application to agricultural production. At present, the agricultural rare earth used in production is mainly a mixed nitrate mainly composed of cerium and lanthanum, because it is used in a very small amount. Therefore, it is called rare earth nitrate or rare earth element fertilizer, or abbreviated as rare earth. According to years of experiments, after the application of rare earths to flower plants, they have achieved a significant effect of promoting flower production, improving quality, and achieving significant economic benefits. This is a new technology with low investment, low cost, quick response, and high efficiency. In the production process of raspberry, you can also try to use rare earth, I believe it will also bring some effect on the high yield of raspberry. The Linhai Horticulture Field in Jilin Province will introduce the following methods for using rare earths in detail:

1. The role of rare earth Huifei

(1) Enhances activity and promotes germination. According to the test, the rare-earth-planted flower plants grow quickly and have emerged neatly with enhanced activity. The seeds of the five-color peppers treated with rare earth were 2 days to 3 days earlier than the control. The seed germination rate increased by about 10%, and the emergence rate increased by 8% to 7.

(2) Promote hair roots and root development. Grape shoots were soaked with rare earth liquid before cutting, and the roots were thick and well developed. According to the survey, the rooting rate of grape cuttings increased by 26.8% over the control in three months, and the rooting staff increased by 40.4%.

(3) Promote resistance. Strong resistance. The rare-earth-affected flowering plants have significantly increased resistance to cold, early and salt-tolerance, and pest resistance. The rare earth chrysanthemum leaf spot disease index was reduced by 48.6% compared with the control, and the disease-prevention effect was “% or more. The frost-reducing effect of rare earth cannabis was significantly reduced, and the frozen leaves were reduced by more than 18% compared to the control plants.

(4) Promote absorption and improve fertilizer efficiency. After application of rare earths to flowering plants, the root systems are developed and the vitality is enhanced. Therefore, the ability to absorb and transform nutrients is increased. In particular, the absorption of phosphorus is significantly increased. At the same time, there is a similar increase in the absorption of nitrogen and potassium, which promotes the improvement of fertilization.

(5) Increase chlorophyll content and increase photosynthetic efficiency. The rare-earth flowering plants are wider and thicker than the control leaves, dark green in color, large in functional leaf area, and high in photosynthetic efficiency.

(6) Promote flowering. Application of rare earth flower plants can promote flowering, early flowering and prolong flowering. The ornamental value was increased, and the azaleas were sprayed with rare earth liquid, and flowering was performed 6 days in advance and 12 days in advance. The flowering period was prolonged by more than 10 days, and the flower color was particularly bright. The application of rare earth micro-fertilizer in grapes can increase the yield by 30% to 35%, and can improve the quality of grapes, increase the vitamin content of fruits and optimize the acid-sweet ratio, and the sugar content increases by 0.7%, which matures in 3 days and 5 days in advance. Potted kumquats were sprayed during the flowering and young fruit period. The fruit setting rate increased by more than 20%.
