Abstract

The invention relates to a high-survival-rate seedling growing method for koelreuteria paniculata. The method comprises the following steps: (1) selecting mature and complete koelreuteria paniculata seeds, mixing the koelreuteria paniculata seeds with plant ash, and stirring; (2) preparing fresh pig blood, adding the koelreuteria paniculata seeds into the pig blood, and processing the koelreuteria paniculata seeds; (3) growing the seedlings of the koelreuteria paniculata seeds; and (4) cutting a leaf closest to the root to form an opening when the koelreuteria paniculata seedling grows until 2-3 leaves are expanded, smearing the opening with 1.2%-1.5% of a sodium acetate solution, and irrigating the roots with the 1.5% of a sodium citrate solution, wherein the irrigation amount of each seedling is 10ml-15ml. By virtue of the method, the survival rate of the seedlings can be increased, the integral survival rate of the grown seedlings is obviously increased, and the economic benefit of the seedling growing of the koelreuteria paniculata is increased.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for raising seedlings of eucalyptus with high survival rate. Background technique [0002] Luan tree is a kind of plant that likes light and is slightly tolerant to half shade; it is cold-resistant; but it is not resistant to flooding, so pay attention to the land when planting, it is resistant to drought and barrenness, it has strong adaptability to the environment, it likes to grow in calcareous soil, and it is resistant to salt and short-term waterlogging . The eucalyptus has deep roots, strong germination ability, and medium growth rate. The growth rate of young trees is slow, and it will grow faster later. It has a strong ability to resist smoke and dust. It is often used as a tree for landscaping. However, when eucalyptus is planted, seeds are often used to germinate and raise seedlings. The germination rate is often 60-80%, and the survival rate after germinat...
