Problems solved by technology

But the problem is that only 2 of the resulting mother branches are left, and the rest have to be removed, which not only takes a lot of work but also reduces production.
The remaining two fruiting mother branches are all cut short, which is easy to cause the fruiting branches to run away, with few fruits and low yield, which is easy to cause secondary fruiting after autumn and reduce the yield in the second year
In addition, this method is labor-intensive, time-consuming and labor-intensive

Embodiment 1

[0044] Location: Chestnut Garden in Geziyu Village, Han'erzhuang Township, Hanerzhuang Township, Qianxi County, Tangshan City, Hebei Province, which is the experimental field for the first trial of the chestnut planting method of the present invention. There are 450 grafted chestnut trees aged 20-30 years, with a total area of ​​8.4 mu. Among them, 47 plants were planted on the flat land, about 0.9 mu; 403 plants were planted around the mountains, equivalent to an area of ​​about 7.5 mu.

[0045] Before 2009, the traditional dovetail branch cutting method was adopted. The average height of the tree was more than 5 meters, the average crown width was about 5.5 meters, and the tree was divided into 3 layers. 2-3 main branches, 1-2 main branches on the third layer, each main branch has 7-11 small branches, and each branch leaves an average of 2 fruiting mother branches; the average labor for pruning is 15 days, and the average yield per mu is about 267 catties , That is, the avera...

Embodiment 2

[0049] Location: Sandaohe Village, Sandaohe Township, Xinglong County, Chengde City, Hebei Province, which is a test field for promoting the chestnut planting method of the present invention.

[0050] There are 353 chestnut grafted trees, totaling 4.3 mu. Before 2013, it took 20 days of work according to the pruning method of swallowtail branches, and the average yield per mu was 132 catties. In 2014, pruning was carried out according to the Pteris branch method of the present invention, and the manpower was reduced to 9 days, and the average yield per mu was 279 jin; in 2015, the manpower was 7.5 days, and the average per mu yield was 372 jin; in 2016, the manpower was 7.5 days, and the per mu yield was 458 jin ; In 2017, it took 7 days of labor, and the yield per mu was 472 jin. After 4 years of pruning, the output in the fourth year has increased by 3.5 times compared with the original one. However, from 2015 to 2017, the average output of other households in Sandaohe Vil...

Embodiment 3

[0052] Location: Shimenzi Village, Hanerzhuang Township, Qianxi County, which is an experimental field for promoting the chestnut planting method of the present invention.

[0053] There are 530 chestnut trees in the mountain floor, among which 510 are 10-25 years old and 20 are more than 25 years old, equivalent to 6.7 mu.

[0054] Before 2016, high-branch shears and dovetail branches were used for pruning, which took a total of 33 days of labor. From 2010 to 2016, the average yield per mu was 388 catties.

[0055] In 2017, the Fengwei branch method was adopted, and the labor was only 12 days, with an average yield of 672 catties per mu.

[0056] Compared with the combination method of high branch shears and dovetail branches, the Pteris pruning method can increase yield by 73.2%, and save labor by 63.6%.

Abstract

The invention discloses a mountain land Chinese chestnut planting method which includes the steps: drilling a circular hole in the center of a radish in transplanting, and placing a main root of a seedling into the circular hole; pasting a grafting opening by environment-friendly high-elasticity glue after grafting by a wood bark side grafting method, and covering the glue on the grafting openingwith a thin film; trim the seedling by a phoenix tail twig trimming method. The method solves the problems of water shortage and water retention of plantation in mountainous lands, transplanting and grafting survival rate is increased, and the method has the advantages of labor-saving and fertilizer-saving properties and high yield.

Description

technical field [0001] The present application relates to the field of plant cultivation, in particular to a method for planting mountain chestnuts. Background technique [0002] Chestnuts are widely planted in mountainous and hilly areas in China. The planting season in the mountainous areas of northern China is usually late autumn and early winter or spring. The biggest problem is water shortage, which leads to high cost and low survival rate of chestnuts in mountainous areas. Do a good job of watering after planting. Water and water retention measures are essential. Chestnut saplings planted in mountainous areas are usually far away from water sources, making water fetching and watering difficult, resulting in high planting costs and low survival rates; if affected by extreme weather, the survival rate may even be lower than 50%. [0003] There are many grafting methods for chestnuts, such as split grafting, budding with wood, cutting grafting, and abdominal grafting wit...
