Transplanting matrix for tissue culture seedlings of pineapple

Abstract

The invention discloses a transplanting matrix for tissue culture seedlings of pineapple. The transplanting matrix consists of an upper layer and a lower layer, wherein the upper layer is a peat soil layer with the thickness of 3 to 4 centimeters, the lower layer is a mixing layer which is formed by uniformly mixing yellow mud, chaff and peat soil in a mass ratio of (8-6) :(3-4):1, and the thickness of the mixing layer is not less than 8 centimeters. The transplanting matrix for the tissue culture seedlings of the pineapple has strong capability of water and nutrient preserving; the tissue culture seedlings of the pineapple transplanted on the transplanting matrix grow quickly; plants grow more quickly along with thickened and increased root systems particularly after being transplanted for 60 days and raise obviously with multiple leaves in long and wide shapes; the survival rate of the tissue culture seedlings is improved obviously; quick rooting is achieved; root coefficient and root length are obviously increased; the plants can basically come out of nursery after being transplanted for 150 days; and the time of the plants coming out of the nursery can be effectively shortened to facilitate the reduction of culture cost on the tissue culture seedlings of the pineapple.

Description

technical field [0001] The invention relates to a substrate for transplanting pineapple tissue culture seedlings. Background technique [0002] Pineapple is one of the high-quality tropical fruits, and it has a large amount of cultivation in South China. [0003] Usually pineapple adopts sprouts to propagate and cultivate, but the propagation coefficient of sprouts is low and the speed is slow. Due to the large planting volume of conventional varieties, generally only sprouts are used to propagate to meet the needs of large-scale cultivation. However, when new varieties are promoted, the use of sprouts for propagation is far from being able to meet the needs of large-scale cultivation. In this case, tissue culture seedlings are generally obtained through tissue culture to meet the needs of new variety promotion and large-scale cultivation. At present, the transplanting medium of pineapple tissue culture seedlings is mainly sandy (river sand) seedbeds, which have poor wate...

AI Technical Summary

Problems solved by technology

At present, the transplanting medium of pineapple tissue culture seedlings is mainly sandy (river sand) seedbed, which has poor water and fertility retention. It is also relatively low, generally around 80%, which greatly reduces the production efficiency of tissue culture seedlings and increases the production cost of tissue culture seedlings
