Problems solved by technology

From the perspective of existing technical methods, the above-mentioned technical methods such as site preparation and replanting, soil filling and direct ditch planting cannot fundamentally solve the problems of waterlogging, drought and low survival rate of tea trees in paddy fields. At the same time, there is a lack of supporting measures such as scientific fertilizer and water management, grass covering, pruning management, etc.

Embodiment 1

[0036] Select the improved variety of tea tree as the cultivar.

[0037]Select a mountain paddy field with high terrain, sufficient light, deep soil, loose soil and good permeability. First, dig out weeds and other debris, plow the land 50-60cm deep, and expose it to the sun for 10 sun days in autumn. Broken earth. Then excavate two drainage and irrigation ditches parallel to the tea row, with a width of 28cm and a depth of 50cm; surrounding ditches are excavated around the tea garden to connect with the drainage and irrigation ditches, the ditches are 40cm wide and 70cm deep; the planting ditches are 40-45cm wide and 40- 50cm, and apply base fertilizer (apply organic fertilizer, cover soil; apply potassium sulfate compound fertilizer, cover soil; apply organic fertilizer again, cover soil; finally apply potassium sulfate compound fertilizer, cover soil; wherein, the organic fertilizer that is applied twice is respectively per mu 900kg, the potassium sulfate compound fertiliz...

Embodiment 2

[0039] Select the improved variety of tea tree as the cultivar.

[0040] Select a mountain paddy field with high terrain, sufficient sunlight, deep soil, loose soil and good permeability, first dig out weeds and other sundries, plow the land 50-60cm deep, and expose it to the sun for 15 sun days in autumn. Broken earth. Then excavate the cross-shaped irrigation and drainage ditch, width 30cm, depth 55cm; excavate the surrounding ditch connected with the drainage and irrigation ditch around the tea garden, width 45cm, depth 75cm; Apply organic fertilizer and cover soil; then apply potassium sulfate compound fertilizer and cover soil; Potassium sulfate compound fertilizer is 55kg per acre, and 6cm-10cm of soil is applied each time); double planting in a single row, row spacing 145-155cm, plant spacing 22-28cm, and intercropping early-maturing soybeans, pouring enough water after planting, depending on the weather Timely replenish water according to the condition, and trim the ...

Embodiment 3

[0042] The tea tree variety Bixiangzao was selected as a cultivated variety.

[0043] Choose a mountain paddy field with high terrain, sufficient sunlight, deep soil layer, loose soil and good permeability, remove weeds and other debris, plow the land 50-60cm deep, and break the soil after 20 sun days in autumn. Excavate a cross-shaped irrigation and drainage ditch with a width of 32cm and a depth of 60cm; dig a surrounding ditch connected with the drainage and irrigation ditch around the tea garden, with a width of 50cm and a depth of 80cm; a planting ditch with a width of 40-45cm and a depth of 40-50cm, and apply base fertilizer (first apply organic fertilizer, cover soil; then apply potassium sulfate compound fertilizer, cover soil; then apply organic fertilizer, cover soil; finally apply potassium sulfate compound fertilizer, cover soil; wherein, the organic fertilizer of 2 application is respectively 1100kg per mu, 2 times The potassium sulfate compound fertilizer applied...

Abstract

A method of using mountainous rice fields to replant tea trees is based on the mountainous rice fields suitable for cultivating tea trees, according to tea tree nutritional physiology and its requirements for water, fertilizer, and environment, using deep plowing and exposure, setting up drainage and irrigation ditches and surrounding ditches, The paddy fields are scientifically sorted out by planting ditches and applying base fertilizers, etc., and then by selecting tea tree varieties with strong stress resistance, planting double plants in a single row, laying grass, shaping pruning, irrigation, and planting shade trees or intercropping green manure plants around the tea garden and other measures to plant and maintain young tea trees, to maximize the solution to the problem that the plow bottom aquifer in mountainous rice fields affects the growth and development of tea trees and leads to the problems of low survival rate, slow gardening and low yield of replanted tea trees, so as to achieve high survival rate of tea trees, Fast gardening, high yield and high quality.

Description

technical field [0001] The present invention relates to planting tea trees, in particular to a method of using paddy fields in mountainous areas to replant tea trees, and in particular to a method for solving the problems of waterlogging and drought in rice fields in mountainous areas when replanting tea trees by deep plowing the land and opening irrigation ditches. Dig deep planting ditch to break the plow bottom problem caused by shallow rice planting, and improve the survival rate, yield and tea quality of replanted tea trees through measures such as selection of excellent tea tree varieties, optimization of fertilizer and water management, and stereotyped pruning. Background technique [0002] Rice is the main food crop in my country. However, due to the relatively high terrain of mountainous rice fields, the annual active accumulated temperature is difficult to meet the heat required for rice growth and development. In addition, the temperature and soil temperature in mo...
