Jiangxi Province Academy of Forestry Bamboo Fertilization Technology BNP Bamboo Yield Enhancer Bamboo Fertilization Promotion Demonstration Sample Plan
1. The main components of BNP Phyllostachys pubescens stimulating agent are extremely effective. Phyllostachys pubescens sinensis is a highly-efficient concentrate prepared mainly from NPK organic nutrient solution, auxin, cytokinin, microbial nutrients, trace elements, and fertilizer additives. , The “three elements†nutrients necessary for the growth of Phyllostachys pubescens and various biological hormones and microelements are integrated into one body. After application, the activity of various enzymes in the metabolic process of Phyllostachys pubescens plants and the activity of the meristem of Hsinchu intermediaries can be effectively improved. Increase chlorophyll content, enhance photosynthesis, increase net light and rate, promote whip root growth and shoot differentiation, increase the amount of pregnant bamboo shoots, the amount of bamboo shoots, and the amount of Hsinchu bamboo, thereby significantly increasing bamboo yield and improving bamboo materials. Sex and bamboo stress resistance.
Second, the principle of bamboo fertilization technology Phyllostachys pubescens, bamboo whip developed in the tubulin has a strong transport function, the bamboo wall and bamboo joint tissue has a strong adsorption and permeability, the bamboo cavity has a high degree Closed. The stimulation agent is injected into the bamboo cavity. After being contacted with the bamboo wall and the septum tissue, the nutrient can be rapidly transported from the lower part to the whip root and from the upper part to the branches and leaves through the osmotic action and the rapid transmission of tubulin. The nutrient solution is not volatilized in the bamboo cavity and is not lost. It is not easy to be fixed and has a large contact surface with the bamboo wall and the septum, and the nutrient applied can be completely absorbed and utilized. The use of this principle for bamboo cavity fertilization can fully meet the demand of “three elements†nutrients, biological hormones and trace elements in high-yield forests of Phyllostachys pubescens, and can achieve rapid whole forest fertilization effects.
Third, bamboo cavity fertilization technical points
1. The transport function of bamboo microtubules and the permeability of bamboo wall and septum of fertilized objects will decrease with the increase of the age of bamboo. Studies have shown that bamboo shoots are fertilized and nutrients can be transported to the next day. Branches and whip roots, 5 years old, can be reached after 8 days. Therefore, for the first time, bamboo shoots can be used for the first time. Hsinchu and old bamboo can be fertilized in the bamboo cavity in order to select bamboos and bamboo leaves less than 3 years old. Well, the second time and later bamboo fertilization forest can only be used for bamboo fertilization in Hsinchu.
2. Fertilization time The bamboo shoots in Hsinchu were fertilized so that the growth of the bamboo plant height was basically stopped until the branching and leaf advancement was well. During this period, the Hsinchu was young and easy to drill. It was possible to drill with a shoe drill and the wound was easy to close. After Hsinchu has been fully developed and even more than 1 year old, it can be fertilized before the end of August. However, due to the aging of bamboo, electric drills are required to drill holes. More than one year old bamboo can be used in the second bamboo cavity fertilization before the spring bamboo shoots unearthed, the effect of increasing production.
3, bamboo fertilization site to bamboo base 10cm below the bamboo is appropriate to cast.
4, bamboo fertilization method fertilization when the first increase in production agent and water into a dilution of 1 to 4, and then "one drill, two shots, three sealed", that is, after drilling with a drill or drilling machine continuous syringe injection Application, immediately after the fertilization, the yellow heart soil is used to seal and inject the injection holes to prevent invasion of the wounds and diseases and insect pests.
5, the amount of fertilizer to the standard diameter of 10cm diameter bamboo, the average strain of the production agent diluted 5ml (raw liquid 1ml), breast diameter greater than 11cm can be appropriate amount of more than less than 9cm can be appropriate Shihao. The number of fertilized plants per acre is 50-60% of the standing bamboo, ie, 200 plants per mu, and 100-120 plants per acre are appropriate. The amount of fertilizer per acre is 100% -120ml.
IV. Matters needing attention and major supporting facilities
1, must strictly control the amount of fertilizer.
2. It is necessary to strictly master the rules for copying bamboo fertilization techniques.
3, such as the old bamboo bamboo fertilization using the electric drill provided by the company must be copied strictly according to the instructions, the length of the drill into the drilling machine to drill to the bamboo cavity can be, should not be too long.
4. Before the fertilization of the uncultivated forests in Lushan, the mountains should be chopped to improve the efficiency of fertilizer application.
5. Implement scientifically harvested bamboo materials, reasonably leave bamboo shoots and keep bamboos, strengthen water management, pest control, and bamboo and other supporting measures.
V. Bamboo Forest Fertilization Extension Demonstration Stand Setting and Comparison of Sample Survey Methods
1. Promotion and demonstration of forest stand settings and requirements (1) Set up and promote demonstration forest stand according to the three types of low, middle and high stand types;
(2) For each type of standing bamboo forest, three types of treatments are used: bamboo cavity fertilization (produced by increasing yield of bamboo), hole application or furrow application of compound fertilizer (or other fertilizers), and no fertilization (control).
(3) The site conditions and stand structure should be basically the same among the three treatment combinations.
(4) Each treatment should have three replicates, each with an area of ​​no less than 15 acres.
(5) Other forest management measures must be the same for each replicate.
2. Promotion of demonstration forest stand effectiveness survey content (1) Stand growth potential: stand bamboo level, stand diameter, mean DBH, change in leaf color, etc.;
(2) The number of fired bamboo shoots: the number of fired bamboo shoots and the change of bamboo shoot diameter;
(3) The number of bamboos: the number of bamboo shoots, the time for bamboo shoots, the number of new bamboo shoots and the percentage of bamboo shoots;
(4) Quality of Hsinchu: Changes in the DBH of Hsinchu;
(5) Soil survey and collection of soil samples.
3. Sample site setting and survey methods (1) The plot area is 400?, and it is better to set it to 20m20m. Use the compass to calibrate the sample plot boundary, set the fixed boundary piles in the four corners, and mark the boundaries with paint on the four sides. The plots of fertilized forests and control (non-fertilizer) forest plots must be representative of the popularized demonstration forest and control forest stand. The shortest distance between the fertilized stand forest plots and the control forest plot plots should be no less than 50 meters. After the sample plot was set up, the investigation of the bamboo shoot growth and the change of bamboo shoot yield were conducted with each bamboo inspection scale method.
(2) Soil surveys were conducted using soil profile methods. The width of the section is 1m. The depth of the section is determined by the depth of the soil layer C. The soil profile must be perpendicular to the horizontal plane. After the soil profile is dug, the soil is surveyed in layers A, B, and C. The main types of parent rock, soil type, soil structure, soil thickness, dryness, soil layer, soil texture, litter layer thickness, and humus layer thickness are mainly investigated. , soil bulk density, porosity, gravel content, pH, tightness and so on. And collect 1 to 2 kg of mixed soil samples.
