However, the current greening nursery stock market attaches great importance to the tree shape of nursery greening seedlings and the growth rate of greening seedlings, while ignoring the improvement of the overall quality of greening seedlings, especially the balance between the aboveground and underground parts, resulting in some greening seedlings. The root growth and development are poor, the survival rate of transplanting is low or even all die

Embodiment 1

[0035] In this example, the root-cutting seedlings are Lechang Michelle, and the root-cutting test was carried out from 2012 to 2014. The specific steps are as follows:

[0036] (1) Preparatory work before root cutting of seedlings: preparatory work before root cutting of seedlings includes determining the root cutting times and years of seedlings to be rooted, determining the root cutting time of seedlings to be rooted, determining the ratio of root cutting of seedlings to be rooted and Determine the root cutting depth of the seedlings to be cut. In the present embodiment, the seedlings to be cut are Michelia Lechang, and its diameter at breast height is 12cm. The root-cutting period of Michelle is 2 years, the root-cutting frequency is 2 times, the root-cutting time is February or March every year, the root-cutting ratio is 50%, and the root-cutting depth is 36cm.

[0037] (2) After the preparatory work before cutting the roots of the seedlings is completed, the tools and ma...

Embodiment 2

[0048] In the present embodiment, the nursery stock that carries out root cutting is mandarin jacket wood, and the time that root cutting test is carried out is 2011~2013, and concrete steps are as follows:

[0049] (1) Preparatory work before root cutting of seedlings: the preparation work before root cutting of seedlings includes determining the number of root cuttings and years of seedlings to be rooted, determining the root cutting time of seedlings to be rooted, determining the ratio of root cutting of seedlings to be rooted and Determine the root cutting depth of the seedlings to be cut. In the present embodiment, the seedlings to be cut are mandarin tree, and its diameter at breast height is 10cm, and the quantity is 30. In view of the mandarin tree is a deciduous tree, the root cutting of the mandarin tree to be cut is determined. The annual limit is 2 years, the number of root cuttings is 2 times, the time of root cutting is October or November every year, the root cut...

Embodiment 3

[0061] The present embodiment is the parallel control root-cutting test of embodiment 1, and the difference with embodiment 1 is: the big tree rooting liquid is watered at the cutting and digging place; the mixture of backfilling the original soil and decomposed fermented cottonseed cake at the cutting and digging place adjacent to the rhizome, The layers are solid; the preparation method of the decomposed fermented cottonseed cake is as follows: mix the dried chicken manure and the cottonseed cake at a mass ratio of 2:1, add water and mix well, and the amount of water added should be just enough to drip in the hand. Cover it tightly with a plastic sheet, and after 30 days, the decomposed and fermented cottonseed cake will be obtained. At the end of 2014, a survey on the survival of the transplanted Lechang Michelia was carried out, and the survey results showed that the survival rate of Lechang Michelle reached 96%.

Abstract

The invention discloses a root cutting method for a green seedling. The root cutting method for the green seedling comprises the following steps that 1 preparation work before root cutting is conducted; 2 materials and tools for root cutting are prepared; 3 cutting is conducted on the seedling to be cut; 4 seedling maintenance is conducted after root cutting is conducted. The root cutting method for the green seedling is easy to master, the effect is remarkable, the root development of the green seedling is facilitated to promote, the balance of overground portion and underground portion of the seedling is reached, and the survival rate of transplanting of the green seedling is improved greatly.

Description

technical field [0001] The invention relates to the technical field of forest cultivation, in particular to a method for cutting roots of green seedlings. Background technique [0002] In recent years, with the development of my country's economy, more attention has been paid to the construction of ecological civilization, and green seedlings have developed rapidly. However, the current greening nursery stock market attaches great importance to the tree shape of nursery greening seedlings and the growth rate of greening seedlings, while ignoring the improvement of the overall quality of greening seedlings, especially the balance between the aboveground and underground parts, resulting in some greening seedlings. The growth and development of the root system is poor, and the survival rate of transplanting is low or even completely dead. After decades of development in the greening seedling industry, the market has higher and higher requirements for the quality of seedlings, ...
