Special compound fertilizer for euscaphis konishii hayata

Abstract

The invention relates to a special compound fertilizer for euscaphis konishii hayata. According to the growth law of euscaphis konishii hayata, one type is a special compound fertilizer for bud seedlings, the best formula is that the mass ratio of N to P to K is 23:6:30, and 0.1g of urea, 0.1g of calcium, magnesium and phosphorus and 0.1g of potassium chloride are applied to a single bud seedling; by adopting the technology, the bud seedling height is increased by 32.16% in comparison with that before fertilization, the leaf number is increased by 7.17%, and the survival rate of bud seedlings in 8 months exceeds 90%; the other type is a special compound fertilizer for seedlings, the best formula is that the mass ratio of N to P to K is 406:105:225, and 3.5g of urea, 3.5g of calcium, magnesium and phosphorus and 1.5g of potassium chloride are applied to a single one-year-old seedling; and by adopting the technology, the seedling height is increased by 35.49% in comparison with that before fertilization, the ground diameter is increased by 15.23%, and the survival rate of seedlings in 18 months exceeds 90%.

Description

Technical field [0001] The invention belongs to a special fertilizer in the field of forestry technology, and specifically relates to a special compound fertilizer for the scallop cylindrica. Background technique [0002] Euspathis konishii Hayata (Euscaphis konishii Hayata) is an evergreen small tree of the genus Hayata in the Staphyleaceae family (Staphyleaceae). It is a native ornamental tree species unique to my country. The trunk of the scalloped jasmine is straight and can be used as a material. The seed oil can be used to make soap, the bark can be used for baking glue, and the roots and dried fruits are used as medicine for rheumatism. In terms of garden applications, in the past, it was mainly planted in garden lawns alone, or planted in small areas, or pruned into bonsai. In recent years, it has been used for street trees or garden viewing. [0003] Because of its unique ornamental and medicinal value, the squash crow has become a highly potential medicinal ornamental t...

[0003] Because of its unique ornamental and medicinal value, Corvus rotundum has become a medicinal ornamental tree species with great potential. At present, the sowing and breeding technology of Corvus rotundum has made breakthroughs, but the seedlings are managed extensively and the pests and diseases are serious. It is highly sensitive to fertilizers. Once the amount of fertilizer is not well controlled, it will cause damage and lead to a large number of deaths. Studies have shown that if no fertilizer is applied in the initial growth stage of the scorpion, the growth will be slow, and the leaves will be yellow. 45cm or less, and excessive and unreasonable fertilization is the main reason for the first year's dull seedlings, slow growth or death, or excessive growth of the seedlings of Crowsia scutellaria; using carbon ammonia and potassium chloride is very easy to burn seedlings, using urea, The effect of calcium, magnesium, and phosphorus is not obvious, and excessive fertilization can easily cause seedling burn. Therefore, the germination rate of Crow's Tree is about 75%, but the preservation rate of sprouts is less than 50%, and the preservation rate of 18 months is less than 30%. , although there are many seeds of Corvus rotundum, it also causes huge waste and is very inconvenient to manage; and in a small number of successful small-scale seedling raising cases in reality, it mainly uses decomposed rare human excrement and urine, but this technology is in the Cannot be realized in large-scale seedling cultivation

For a long time, due to the lack of special compound fertilizers, forest farmers have been accustomed to purchasing compound fertilizers from the market for application. However, the nutrient ratio of the compound fertilizers on the market is not suitable for the growth of buds and seedlings of C. Therefore, there is an urgent need to develop a special compound fertilizer suitable for the growth of buds and seedlings of C.
