Planting method for improving soil quality of eucalyptus plantation

Abstract

The invention relates to the technical field of planting and in particular to a planting method for improving soil quality of eucalyptus plantation. According to the planting method provided by the invention, virus-killing powder is adopted for virus-killing and sterilization of land to be used for planting, a planting environment of the land to be used for planting can be effectively improved, and an organic fertilizer I is also used for optimizing the planting land before planting of white flower lentils; an organic fertilizer II is also used for fertilizing the white flower lentils according to the growth status of the white flower lentils in the process of planting the white flower lentils so as to effectively ensure the growth of the white flower lentils; and after one batch of the white flower lentils is planted, overturning the soil, burying the white flower lentils into the soil, adding activated microorganisms to decompose fresh branches and leaves of the white flower lentils,then performing relay cropping of eucalyptus, and in the relay cropping process, in addition to providing sufficient fertility for the eucalyptus, the nitrogen-fixing ability of the white flower lentils and the decomposition of the white flower lentils by probiotics are further utilized for supplementing to soil organic matters, and the purpose of improving the soil quality of the eucalyptus plantation can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of planting, in particular to a planting method for improving the soil quality of a eucalyptus plantation site. 【Background technique】 [0002] Eucalyptus is one of the three fast-growing tree species (eucalyptus, poplar, pine) in China. With the advantages of fast growth, eucalyptus trees can achieve the effect of forestry in the same year if they are planted in the same year. Therefore, eucalyptus enjoys a high reputation and is favored in my country, especially in tropical and subtropical regions such as Guangxi, Guangdong, Hainan, and Fujian. The planting of eucalyptus has the characteristics of superior conditions, a long history, and good benefits. At present, Guangxi Eucalyptus wood production accounts for more than 70% of the total timber production in the region, and the development of eucalyptus plantation has good benefits. The large-scale planting of eucalyptus has many positive ecological eff...

If this goes on for a long time, it will inevitably cause excessive consumption of soil nutrients and loss of soil nutrient pool.

If sufficient nutrient elements are not replenished and returned to the soil in time, the eucalyptus will naturally become a "fertilizer". Due to the rapid growth of the eucalyptus, the soil fertility will decline and the fertility will decline, which will make it difficult for other plants to grow, or even difficult to grow. It is easy to cause water shortage and rocky desertification after the felling of eucalyptus

[0003] At present, there are many researches at home and abroad using the symbiotic interplanting method of eucalyptus and pasture, but only a small part of pasture can survive; Semen dolichoris Album is a leguminous plant with strong nitrogen fixation ability. Interplanting with eucalyptus will greatly improve the soil quality of the eucalyptus plantation site, but after research, at present, the white-flowered lentils cannot be interplanted with eucalyptus. The inventor of this application has just done such research in this field. On March 10th, on page 137 of "Heilongjiang Animal Husbandry and Veterinary Medicine" impurity, page 138 of the article "Research on Interplanting Eucalyptus and Forage Grass" pointed out: "Only part of the white-flowered lentils and fast-growing Sophora japonica survived, and the growth was slow."
