Abstract

The invention relates to the technical field of agricultural planting, specifically to a field management method for 1-to-3-year-old citrus saplings. The method provided by the invention comprises thefollowing steps: in the first year to the third year after citrus planting, respectively carrying out topdressing once every March, May and July, adding botanical herbicidal components into a topdressing fertilizer, and spraying a botanical herbicide once every April and September, wherein the weight ratio of the topdressing fertilizer to the botanical herbicidal components is 100: (4-16), and the topdressing manner of the topdressing fertilizer is to directly dig a topdressing ditch at the position of 16 to 30 cm far away from a citrus tree for fertilization. The field management method forthe 1-to-3-year-old citrus saplings provided by the invention has the following advantages: a herbicide used in the method is a botanical herbicide, is fast-acting, has significant herbicidal effect,is free of herbicide residue, and is insusceptible to generate herbicide resistance and the accumulation action of toxic and side effects.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural planting, in particular to a field management method for 1-3 year old citrus saplings. 【Background technique】 [0002] Guangxi is one of the important origins of citrus, with rich citrus resources, a wide variety of fine varieties, and a long history of cultivation. The composition of citrus is composed of: roots, stems, leaves, flowers and fruits. The growth and development of citrus fruit trees, flowering and fruiting are closely related to environmental conditions such as temperature, sunshine, moisture, soil, wind, altitude, terrain and slope aspect, and these conditions affect the temperature the most. Citrus has a wide range of adaptability to soil, purple soil, red-yellow soil, sandy beach and tidal flats can grow at a pH value of 4.5-8, with a pH value of 5.5-6.5 being the most suitable. The growth of citrus root system requires higher oxygen content, and the soil texture is loose...
