Problems solved by technology

Although this method can effectively inhibit the growth of weeds in tea gardens for 1-2 years, and does not need to be planted year after year, Cassia feather leaves or Cassia garden leaves are suitable for tea garden planting in acidic soil, while the pitaya orchard soil in southern Guizhou is alkaline. In addition, there are many differences in planting patterns and weed control requirements between tea gardens and pitaya orchards.
In addition, the seed coat of Cassia rotifera or Cassia pinnata is hard, with poor permeability and water absorption, so seed treatment must be carried out before sowing, which increases the cost of planting

Embodiment 1

[0020] A method for preventing and treating summer weed damage in mountain pitaya orchards, comprising the following steps:

[0021] 1. Sowing Chixiaodou: In the first year before the Qingming Festival, lightly dig the soil in the mountain pitaya orchard, dig out the roots of weeds such as ghost needle grass or yellow thatch, and sow Chixiaodou avoiding the crown of the tree. The sowing rate is 4kg / mu.

[0022] 2. Yicut Chixiaodou: In the middle and late October of the first year, after the Chixiaodou plant turns yellow and the beans fall to the ground, cut off the Chixiaodou from the root with a lawn mower, and cover the Chixiaodou stalks on the dragon fruit tree tray.

[0023] 3. Sowing arrow tongue peas: After cutting Chixiaodou, sow arrow tongue peas in the Chixiaodou planting area, lightly turn over the remaining branches and leaves of Chixiaodou, cover the arrow tongue peas, and sow at a rate of 4kg / mu.

[0024] 4. Cutting the arrow tongue pea: Before the arrow tongue pe...

Embodiment 2

[0027] A kind of control method for mountain dragon orchard ghost needle grass, comprises the following steps:

[0028] 1. Sowing Chixiaodou: In the first year after the Qingming Festival, lightly dig the soil in the mountain pitaya orchard, dig out the roots of weeds such as ghost needle grass or yellow thatch, avoid the crown of the tree and spread Chixiaodou at a rate of 3kg / mu.

[0029] 2. Yicut Chixiaodou: In the middle and late October of the first year, after the Chixiaodou plant turns yellow and the beans fall to the ground, cut off the Chixiaodou from the root with a lawn mower, and cover the Chixiaodou stalks on the dragon fruit tree tray.

[0030] 3. Sowing arrow tongue pea: After cutting Chixiaodou, sow arrow tongue pea in the Chixiaodou planting area, lightly turn over the remaining branches and leaves of Chixiaodou, and cover the arrow tongue pea, the sowing rate is 3kg / mu.

[0031] 4. Cutting the arrow tongue pea: Before the arrow tongue pea blooms in large quan...

Embodiment 3

[0034] Sowing Chixiaodou in early March, because the soil is dry, the emergence rate is low, and the uniformity of emergence is poor, so it needs to be replanted in mid-to-late April.

Abstract

The invention belongs to the technical field of pitaya cultivation, and particularly relates to a prevention and control method for summer weed damage of a mountain pitaya orchard. According to the prevention and control method for the summer weed damage of the mountain pitaya orchard, annual grass of phaseolus calcaratus and common vetch is adopted to prevent and control weeds in the pitaya orchard, particularly, the effect of preventing and controlling spanishneedles herb and yellow couch grass is outstanding, manual cutting is only needed twice in one year, manual weeding is not needed in summer, and the cost is greatly reduced; while the weeds are prevented and controlled, soil organic matters of the mountain pitaya orchard in Guizhou are increased, and the application and planting cost of base fertilizer in winter is reduced.

Description

technical field [0001] The invention belongs to the technical field of dragon fruit cultivation, and in particular relates to a method for preventing and treating summer weeds in mountain pitaya orchards. Background technique [0002] Pitaya orchards in southern Guizhou are severely damaged by weeds in summer, and ghost needle grass and yellow thatch are one of the main harmful weeds. They need to be mowed every 20-30 days from June to October, which requires a lot of labor. Pests will increase the probability of occurrence of plant diseases and insect pests in pitaya orchards, resulting in reduced fruit quality. [0003] Ghost needle grass is an annual herb of Compositae. It likes to grow in warm and humid climate areas. It is suitable for loose, fertile, humus-rich sandy loam and clay loam. It has a well-developed root system, a strong ability to absorb soil moisture and nutrients, and a strong growth advantage. Water and fertilizer consumption often exceed the consumptio...
