[ detailed description ] embodiments
In order to facilitate a better understanding of the invention, the following examples are given to illustrate, but not to limit the scope of the invention.
The invention researches the relation between different fat-collecting intervals and the fat yield and the relation between different lateral ditch cutting step distances and the fat yield, and selects the optimal process parameters of the fat-collecting interval period, the cutting depth and the cutting load rate, thereby providing a theoretical and data basis for realizing the achievement of larger economic benefits of fat and material production.
(I) relationship between different intervals of blood fat sampling and amount of blood fat produced
In 2015, a 12-year contrast test of different fat-collecting intervals and fat yields of the pine abroad was carried out at the Linke department in Hepu county. The test set is 4 treatments of 12-year-old foreign pine, including 3 days 1 harvest, 2 days 1 harvest, 1 day 1 harvest and 1 day 2 harvest, and the number of grease collecting plants in each treatment is 35 by selecting the sample plot with similar soil fertility and slope direction. The test result shows that: (1) in the 1 st year of the initial fat collection, the fat yield is highest in 2 days 1 and the fat yield is lowest in 1 day 3; (2) the results of the 2 nd and 3 rd years of fat collection are opposite to the 1 st year, the fat yield of 1 st collection in 3 days and 1 st collection in 2 days are respectively 1.9 times and 1.5 times of that of 2 nd collection in 1 day, the fat yield of 1 st collection in 1 day is third, and the fat yield of 2 nd collection in 1 day is lowest; (3) the test result also shows that the interval period of the oil extraction not only affects the output of the pine resin, but also affects the breast diameter and the volume of a single plant, the 1-day 2-extraction has the lowest oil yield under the condition of continuous oil extraction for a plurality of years, the annual breast diameter growth amount is respectively reduced by 55 percent and 45 percent compared with the 3-day 1-extraction and the 2-day 1-extraction, the secant face consumption is respectively increased by 50 percent and 40 percent, and the labor capacity is respectively increased by 6 times and 4 times. Therefore, the large-scale fat collection of foreign pine is recommended to be popularized for 1 collection in 3 days or 1 collection in 2 days.
(II) relationship between different cutting depths and fat yield
In 2015, 12-year-old slash pine different fat collection depths (depth into xylem) and fat production amount experimental studies were conducted in the forestry department of Hepu county, 3 sets of 0.5cm, 0.8cm and 1.2cm cutting depth treatments were set, and the number of fat collection strains in each treatment was 35 by selecting the same plot with similar land strength and slope direction. The test result shows that: (1) the difference of the different cutting depths to the output of the pine resin and the growth quantity of the breast diameter is not obvious; (2) but the cutting depth can affect the quality of the wood, the cutting depth is too deep, the quality of the wood is reduced, and the purchase price of the wood is reduced; meanwhile, the cutting depth of 0.8-1.2c is easy to cause slight tearing of wood, wind falling and breaking from the cutting surface, thus causing economic loss. On the premise of balancing the yield of wood and rosin, the optimal cutting depth suggested to be popularized in production is 0.5 cm.
(III) relationship between different cutting load rates and fat yield
In 2015, a comparison test of different cutting load rates and fat yields of 12-year-old foreign pines was carried out in Linaceae in Hepu county, and in the test, 3 fat-collecting load rate treatments of 40%, 55% and 70% are set in a 16-18cm diameter step (breast diameter 15.0-18.9cm), sample plots with similar soil fertility and slope direction are selected in the test, the number of fat-collecting strains in each treatment is 35, and 5 fat-collecting strains are not used as controls. And (3) carrying out continuous 2-year fat collection analysis, wherein the test result shows that: (1) in the 1 st year of the initial fat collection of 16-18cm diameter order, the fat yield difference of 3 different fat collection load rates reaches a significant level, the yield is sequenced into that the fat collection load rate is 40 percent, 55 percent and 70 percent, and the fat yield of 70 percent is respectively 1.52 times and 0.97 times of the fat collection load rate of 40 percent and the fat collection load rate of 55 percent; (2) in the 2 nd year of resin collection, the difference of the pine resin yield among different resin collection load rates is obvious, but the sequencing of the yield is opposite to the 1 st year, the results show that the resin collection load rate is more than 70% and more than 55% and more than 40%, in addition, the resin collection load rate has important influence on the breast diameter growth, the breast diameter annual growth rate sequencing is that the resin collection load rate is more than 70% and more than 55% and more than 40%, the breast diameter growth rate with 70% of the resin collection load rate is only 0.32cm, the resin collection load rate reaches 0.96cm, the condition that the resin collection load rate is too large under the continuous resin collection condition simultaneously influences the pine resin yield and the wood yield, and the overload resin collection is not advisable at the cost of consuming the normal growth of forest trees and the long-term yield of the pine resin. The production suggests that the load rate of medium-long term fat extraction is 40-55%, and the load rate can be below 70% only under the specific conditions of short term fat extraction or pre-harvest strength fat extraction.
(IV) area formula of mining and cutting
The traditional high-load fat sampling seriously influences the growth of foreign pine, is not beneficial to realizing the balanced development of fat production and material production, and achieves the aim of obtaining larger economic benefit. On the basis of researching the requirements of the resin production forest and the resin production technology and selecting better process parameters such as the resin production interval period, the cutting depth, the cutting load rate and the like, the invention adopts a single-sided strength resin production method to produce resin for 3-5 years before felling, and increases the income of pine resin on the premise of not obviously influencing the growth of wood. The specific area of the collected fat is calculated according to the following formula:
Figure BDA0002398916640000041
in the formula: s represents the area of foreign pine resin production; n represents the year of mining and cutting, and n is more than or equal to 1 and less than or equal to 8; d1Representing the diameter of the breast during extraction; dnRepresenting the breast diameter of the nth harvest year, △ D tableMean increase of chest diameter in year; dnIs set as the first item D1The tolerance is △ D, pi is circumference ratio, 3.14 is taken, gamma is the fat-collecting load rate, L is the step pitch value, and D is the number of days of fat collection.
According to the invention, the fat-collecting load rate is strictly controlled, a certain amount of nutrients conveyed by the bark is reserved, and the healthy growth of foreign pine is realized, so that the greater economic benefits of fat production and wood production are realized, and the problems that the growth of foreign pine is seriously influenced by the traditional single-sided high-load short-term fat collection, the yield of the wood is greatly reduced, and the like are effectively solved.
