Problems solved by technology

[0003] In the cultivation process of Dingtan Zanthoxylum bungeanum plantation, there is a prominent problem, that is, the phenomenon of mature leaves falling more seriously in autumn and winter, because the leaves are the main place for the formation of photosynthetic products of Zanthoxylum bungeanum, and they are also the safety valve to deal with hydraulic imbalance, thus hindering The normal progress of photosynthesis affects the accumulation of photosynthetic synthesis and metabolites, which limits the formation of the next year's yield and quality. Some pepper farmers are planning to give up the cultivation of peppercorns, and even return trees to plowing.
At the same time, after the old leaves fall, new leaves continue to germinate, which consumes more nutrients stored in the tree for the construction of growth organs, which intensifies the nutrient limitation in nutrient-poor habitats, hinders reproductive growth, and significantly increases the difficulty of management

Embodiment 1

[0036] A method for preventing the fall of the top altar prickly ash in autumn and winter, comprising the following steps:

[0037] 1. Water and fertilizer management

[0038] (1) On July 20-21, 2019, after the prickly ash was harvested instead of cut, an organic fertilizer made from fresh pig manure decomposed for 30 days was applied as a base fertilizer, with an amount of 4kg / plant, 60cm away from the trunk, and a depth of 35cm , Fertilization in ring ditch, organic fertilizer and soil are fully mixed evenly according to the mass ratio of 1:2.

[0039] (2) According to the growth habit of Dingtan Zanthoxylum bungeanum, in early August, mid-November, 2019 and late March, 2020, Xiyangyou produced by Guizhou Nuoweishi Biological Engineering Co., Ltd. was applied. + Compound fertilizer (N-P 2 o 5 -K 2 O is 15-15-15) 3 times, each dosage 0.25kg / plant. In order to improve the utilization efficiency of fertilizers, the soil water content should be greater than 30% when fertili...

Embodiment 2

[0052] A method for preventing the fall of the top altar prickly ash in autumn and winter, comprising the following steps:

[0053] 1. Water and fertilizer management

[0054] (1) On July 24, 2020, after the prickly ash was harvested instead of sheared, the organic fertilizer made from fresh pig manure decomposed for 30 days was applied at one time as the base fertilizer. 40cm, fertilize in a circular ditch, and mix well with the soil at a mass ratio of 1:2. When fertilizing, prevent the organic fertilizer from being exposed to the ground.

[0055] (2) According to the growth habit of Dingtan Zanthoxylum bungeanum, in mid-August, late November, 2020, early March, and mid-April, 2021, apply Xiyangyou produced by Guizhou Nuoweishi Biological Engineering Co., Ltd. + Compound fertilizer (N-P 2 o 5 -K 2 (2 is 15-15-15) 4 times, and each consumption is 0.2kg / strain. In order to improve the utilization efficiency of fertilizers, the soil water content should be above 35% (moni...

Abstract

The invention discloses a method for preventing leaf falling of zanthoxylum bungeanum maxim in autumn and winter and application of the method, and belongs to the technical field of crop planting. The method mainly comprises the following steps: (1) water and fertilizer management; (2) red rust prevention and control; (3) branch management. According to the method, the leaf falling condition of the zanthoxylum bungeanum maxim can be remarkably improved, meanwhile, the yield of the zanthoxylum bungeanum maxim is increased, and the content of essential amino acid, non-essential amino acid, umami amino acid, bitter amino acid, pharmacodynamic amino acid, carotene, vitamin E and the like in the peel of the zanthoxylum bungeanum maxim and the dry matter content of the zanthoxylum bungeanum According to the method for preventing leaf falling of the zanthoxylum bungeanum maxim in autumn and winter, the yield and quality of the zanthoxylum bungeanum maxim are improved, and a foundation is laid for stability and sustainability of the zanthoxylum bungeanum maxim ecological industry.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a method for preventing top altar prickly ash from falling leaves in autumn and winter and an application thereof. Background technique [0002] Dingtan Zanthoxylum bungeanum is a unique ecological restoration plant in the karst dry-hot valley area of ​​Guizhou. From the perspective of ecological type, it belongs to the dry-heat type, which is quite different from the habit of the damp-heat type Nine-leaf Green Zanthoxylum bungeanum. Therefore, its management technology should also be compared with other plants. Pepper varieties are distinguished. In terms of use value, Dingtan Zanthoxylum bungeanum has the same origin as medicine and food. It is famous for its "strong fragrance, heavy numbness, and high yield". At present, the promotion area of ​​Dingtan Zanthoxylum bungeanum has reached more than 800 hectares, becoming one of the most popular varieties of Zan...
