Planting technology for improving clone tea seedling orchard building survival rate

Abstract

The invention discloses a planting technology for improving the clone tea seedling orchard building survival rate. A leeward and sunny flat land or a gentle slope land smaller than 15 degrees is selected as a land parcel, the pH value of soil is required to be 4.5-6.5, and the soil thickness is 80cm or more; single-row planting is conducted, specifically, the row width is 1.5 m, the hole distanceis 20 cm, two plants are planted in each hole, and 4500 plants are planted per mu; a large row width is 1.6 m, a small row spacing is 30 cm, a cluster spacing is 30 cm, tea trees are arranged in a staggered mode, two tea trees are planted in each hole, and 5000 tea trees are planted per mu; a white light-transmitting film supporting shed is built by bamboo splits in winter for tea seedling plantedin autumn, a greenhouse effect is created, and cold-proof seedling protection is achieved, wherein the length of each bamboo split is 1-1.8 m, one bamboo split is arranged every 30 cm, an arch shapeis formed, the thickness of a plastic film is 0.4 mm, the width of the plastic film is 1-2 m, the periphery of the plastic film is pressed by soil, and the supporting shed is uncovered after the air temperature rises again in March of a next year; the bamboo splits and the plastic film can be repeatedly used for one year; after the tea seedlings are transplanted, if the tea seedlings are dry for along time and have no rain or have drought, watering is conducted in time; timely draining waterlogging is conducted in cloudy and rainy days; in May to August in summer, a 75% shading net is used for covering for sun protection, and survival of the seedlings is guaranteed. The tea trees are high in survival rate, early in germination, high in bud and leaf quality and remarkable in benefit.

Description

technical field [0001] The invention relates to the technical field of tea planting, in particular to a planting technique for improving the survival rate of cloned tea seedlings in gardening. Background technique [0002] Tea tree clonal tea seedlings are a kind of asexual reproduction technology cultivated by cuttings of tea tree branches in the female parent garden, and can also be called "plant cloning". It is genetically stable and can maintain the consistency of the specific characteristics of the excellent traits of the parents; the seedlings cultivated with tea seeds are called sexual reproduction; the seedling tea gardens cannot guarantee the purity of the tea seedlings. Even if the tea seeds picked from the pure-bred female parent garden are bred, there will be seeds that are cross-pollinated by insects, and there will be separation and variation after planting. [0003] The newly cultivated young tea garden has poor soil and bare surface. At the same time, due to...

AI Technical Summary

Problems solved by technology

[0003] The soil of Xinken young tea garden is poor and the surface is bare. At the same time, due to the influence of the environment, the sun is hot in summer and the water is easy to lose. In winter, due to the cold, it will freeze itself and affect the survival rate.
