Problems solved by technology

However, in recent years, various disadvantages have appeared in the shelterbelt with poplar as the main body. For example, the shelterbelt with poplar as the main tree has a single species and serious pest damage. Once the beetle pest occurs, it will give poplar a devastating blow; The effect of the tree side is significant, the transpiration consumes a lot of water, and the contradiction between agriculture and forestry is becoming more and more prominent; moreover, the life span of the poplar shelterbelt system is short, the leafless period is long, and the time to fully exert its protective effect is short. In areas with poor soil texture, improper management is prone to occur. "Little old man tree", the protection system is extremely degraded, and the protection effect is seriously lost

example 1

[0020] Construction of pure sylvestris sylvestris pine shelterbelts: After the soil thawed in early April 2001, single-row sylvestris sylvestris sylvestris pine shelterbelts were directly planted on the farmland without shelterbelts. The construction site of Pinus sylvestris forest belt is also an irrigation channel. Therefore, the planting of Pinus sylvestris is generally combined with the canal. The sylvestris sylvestris is planted on the side of the canal. The size of the loose soil ball is determined, generally 1.5 times the size of the soil ball, so as to facilitate the planting of seedlings. Choose sylvestris pine with vigorous growth, beautiful tree shape, and no pests and diseases as seedlings for building shelterbelts. Pinus sylvestris must be transplanted with a soil ball. The size of the soil ball is 5 to 6 times the diameter of the seedling, and the height of the soil ball is 70% to 80% of the diameter of the soil ball. The height of the transplanted Pinus sylvestr...

[0022] "Replacing pine with poplar" shelterbelt forest transformation: starting from the whole shelterbelt system, shelterbelts should be renewed at intervals, that is, shelterbelts in the same direction should be renewed at intervals, so as to reduce the disadvantage of the decline in protective function due to one-time renewal . One to two rows of Pinus sylvestris can be planted at a time. Pinus sylvestris is a light-loving plant. If two rows are planted, each plant in the second row should be planted in the middle of the first row to avoid shading. Increase light time. Pinus sylvestris belongs to the positive tree species. If it is multi-row poplar shelterbelts to be regenerated, the regeneration should start from the sunny side, and the shelterbelts on the sunny side should be thinned or planted on the original site after a certain distance. On the basis of the forest belt, a successor forest belt is planted on the sunny side of the forest belt. After the newly planted fo...

[0025] "Combination of pine and poplar" to create a shelterbelt: The combined pine and poplar shelterbelt camp was built in mid-April 2003. A row of mixed shelterbelts were constructed by mixing Pinus sylvestris sylvestris and Populus sylvestris , and the distance between pine and Populus sylvestris was 2.5m. The afforestation method is basically the same as example 1. Dig a ditch next to the ditch on the side of the farmland. The ditch is 90 cm wide and 40 cm deep. Weeds and trees in the ditch are removed, and then afforestation is carried out. For afforestation, the height of Pinus sylvestris is 1.2-1.5m, the crown width is 0.8×1.0cm, and it is transplanted with soil balls. Irrigate in time after planting, and the rest of the management methods are the same as in Example 1. At the end of the survey, the survival rate of Pinus sylvestris reached over 98%. The poplar is selected from Xinjiang poplar, which comes from the 4-year-old seedlings cultivated by the Minqin Sand Co...

Abstract

The invention relates to the technical field of farmland shelterbelt construction, and specifically relates to an arid desert region protection forest system construction method. The method comprises the following steps of: seedling cultivation, wherein the seedling cultivation comprises pinus sylvestris seedling cultivation and poplar seedling cultivation, and for poplar, Erbai poplar and Xinjiang poplar are preferentially selected; selecting of an afforestation land and determining of specifications of planting pits; selecting of a planting season; determining of afforestation methods; and tending and management. According to the method provided by the invention, research is performed on such farmland shelterbelt transformation and construction technology as "using pines to change poplars, combining pines with poplars, and combining pines with pines". The research results can effectively overcome the technological bottlenecks in the combination reconstruction and shelterbelt construction in arid desert region pinus sylvestris, pinus sylvestris and poplar, and pinus sylvestris and picea mongolica, thereby having strong practical value and profound practical significance in the arid desert region shelterbelt restruction and construction.

Description

technical field [0001] The invention relates to the technical field of farmland shelterbelt construction, in particular to a method for building a shelterbelt system in an arid desert area. Background technique [0002] In arid desert areas, farmland shelterbelts can regulate temperature, increase air humidity, reduce wind speed, reduce evaporation, improve farmland microclimate, reduce the damage of dry and hot wind to crops, and play a positive role in increasing agricultural production and farmers' income. However, in recent years, various disadvantages have appeared in the shelterbelt with poplar as the main body. For example, the shelterbelt with poplar as the main tree has a single species and serious pest damage. Once the beetle pest occurs, it will give poplar a devastating blow; The effect of the tree side is significant, the transpiration consumes a lot of water, and the contradiction between agriculture and forestry is becoming more and more prominent; moreover, t...
