Abstract

The invention discloses a sustained and controlled release herbicide-fertilizer granule for eucalyptus and a preparation method of the sustained and controlled release herbicide-fertilizer granule. The herbicide-fertilizer granules are prepared from the following raw materials in parts by weight: 0.04-0.21% of hexazinone, 30-65% of fertilizer, 0.02-0.05% of a microbial agent (the number of effective viable bacteria is greater than or equal to 10 billion cfu/g), 0.2-0.5% of gamma-polyglutamic acid, 10-20% of humic acid, 5-10% of a seaweed fermentation product, 0.75-1.2% of a coating agent and the balance of auxiliary materials. The preparation method comprises the following steps: preparing the pesticide fertilizer core, wrapping the coating layer, and wrapping the soil improvement layer. According to the invention, different types of fertilizers are compounded with hexazinone which is an active ingredient of a herbicide and has a sealing effect according to the characteristic of nutrients required by eucalyptus in different growth periods by utilizing the principle of pesticide-fertilizer interaction, and a coating slow release technology is combined, so that the requirement of fast-growing eucalyptus plants on the nutrients is met, and meanwhile, the effect of controlling weeds is also realized.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a slow and controlled release eucalyptus herbicide fertilizer granule and a preparation method thereof. Background technique [0002] Eucalyptus has the characteristics of strong adaptability, fast growth, resistance to barrenness, and strong stress resistance, and is widely planted all over the world. At present, eucalyptus has become the main tree species for afforestation in southern my country. However, with the growing expansion of eucalyptus planting area and the increase of continuous planting generations, the phenomenon that soil fertility cannot make ends meet is becoming more and more serious. In some areas, the lack of land fertility has directly caused physiological diseases of eucalyptus, which has directly affected the sustainable management of eucalyptus plantations. Relevant studies have shown that rational fertilization can improve the growth of eucalyptus, ...
