Problems solved by technology

Only inorganic chemical fertilizers are used in the types of fertilizers, and fertilization is mostly based on experience, or the amount of fertilizers is too large, which not only results in low fertilizer utilization efficiency, but also causes seedling burn
Either the amount of fertilizer applied is too low, which will affect the later growth of plants and greatly affect the effect of land reclamation and ecological reconstruction

Embodiment 1

[0019] 1 Materials and methods

[0020] 1.1 Test materials

[0021] 1.1.1 Reed species tested

[0022] The seeds of the test plant Neyraudia reynaudiana were collected from wild reeds in South China Agricultural University. The seeds were sown in a seedbed with river sand as the substrate for cultivation. When the seedlings grew to a height of about 30 cm, they were taken out from the seedbed and randomly selected. 27 groups of seedlings with no significant difference in plant height, number of tillers, and fresh weight (P<0.05) were set aside.

[0023] 1.1.2 Vermicompost, rice straw and chemical fertilizers tested

[0024] (1) Preparation of vermicompost

[0025] Moisten the air-dried cow dung after natural composting to 60% of the saturated water content, add 100 pieces of Eisenia foetida (fresh weight about 30g) to 1kg of dry cow dung, and add fresh live worms to the cow dung. Earthworms were cultured at room temperature for 2 months to allow all materials to be fully d...

[0069] 1 Materials and methods

[0070] 1.1 Test materials

[0071] Test material is with embodiment 1.

[0072] 1.2 Experimental design

[0073] The experiment was set up as a multi-factor experimental design with different fertilization levels under crop cultivation conditions, with a total of 5 treatments, each treatment repeated 3 times, and a total of 15 pots. Among them, CK is the control without fertilization, "rice straw + chemical fertilizer" treatment group 1 was applied with N, P, K fertilizer and rice straw; "rice straw + chemical fertilizer" treatment group 2 was applied with chemical fertilizer Group 2 and other N, P, K fertilizers and rice straw. The specific dosage of each treatment is shown in Table 7.

Abstract

The invention belongs to the technical field of land reclamation, and concretely discloses a scientific fertilizing method of Neyraudia reynaudiana. An organic and inorganic combination fertilizing technology is adopted based on a sustained and controlled release fertilizing principle and the physiologic characteristics of a fertilizer according to the characteristics of destroyed land soil and the seedling stage fertilizer demanding characteristics of Neyraudia reynaudiana in production construction activity, so the physical and chemical properties of soil can be reconstructed, the root growth and the plant tillering of Neyraudia reynaudiana can be promoted, seedlings can be cultivated and strengthened, and the fertilizer utilization rate and the fertilizer efficiency release speed can be improved. The method is in favor of realizing a fertilizer long-term effect, realizes soil improvement and fertilizer increase, and promotes the long-term growth of Neyraudia reynaudiana.

Description

technical field [0001] The invention relates to the technical fields of land reclamation, ecological reconstruction and water and soil conservation, and specifically discloses a scientific fertilization method of the pioneer plant reed. Background technique [0002] Production and construction activities such as mining and road construction have brought economic development and prosperity, but also brought negative impacts on environmental damage. Among them, the occupation of a large amount of land resources and serious soil erosion are the most important problems faced by various production and construction. Environmental issues. In order to protect land resources and prevent soil erosion, it is an inevitable choice to carry out reclamation and ecological reconstruction of damaged land in the process of production and construction. Due to a large number of excavation and filling activities in mining and highway construction, the topsoil and even the entire soil are lost, ...
