Abstract
The invention discloses a method for fasting determining the early-stage fallen leaf quantity and/or the fallen leaf rate of a fruit tree. According to the method, an anti-bird net is adopted for enclosing a target fruit tree plant, in addition, four simple bamboo poles or branches are adopted for supporting, the net edge is drooped to the ground, then, broken stone or bricks and the like are used for pressing the net, and fallen leaves are prevented from flying away from a three disc. The fallen leaf quantity of the tree disc is gradually calculated by a calculator at the specific period, and in addition, the fallen leaves are cleaned out of the tree disc; and the fallen leaf quantity at different periods is accumulated and summarized, and the fallen leaf quantity and the fallen leaf rate of the target plant at different periods are sequentially calculated. The method has the advantages that simplicity, convenience and high speed are realized, and the determining samples are great, so the early-stage fallen leaf quantity and the fallen leaf rate of the fruit tree can be accurately determined, most importantly, the fallen leaf quantity change of the fruit tree can be continuously determined at the fixed point, the dynamic change of the early-stage fallen leaves in the growth process of the whole plant of the fruit tree can be accurately tracked, the error caused by branch differences in the traditional fruit branch marking method is avoided, and the important practical value is realized for studying the fallen leaf dynamic state of the fruit tree.
Description
Technical field
The invention belongs to plant physiology and plant developmental biology field, relate to the method for a kind of Fast Measurement fruit tree early leaf fall amount and/or defoliation yield.
Background technology
Pathology, the physically different phenomenons such as plant (fruit tree) early leaf fall that cause based on factors such as global warmings, cause gradually relevant scholar's attention, therefore in the research growth and development of fruit tree was dynamic, this index of early leaf fall amount and defoliation yield also received related science worker's concern gradually.Although the pertinent literature report is very few at present, but it is the common method that everybody generally acknowledges that the part document shows the fruit tree tracer method, its principle is to select representative plant, randomly draw 4～10 in peripheral branch at the fruit tree different directions, the difference listing mark, the fruit tree early leaf fall quantity of investigation blade amt and different times is added up early leaf fall amount or the defoliation yield of fruit tree in certain at last in period.The method will fruit tree plant east, south, west, north, in five or several different directions respectively marks and statistics wattles fallen leaves quantity, weighted mean then, the sample statistics complexity is loaded down with trivial details; The individual difference of each different positions branch has more caused the generation of systematic error, and the data that draw can not reflect fallen leaves amount or the defoliation yield of fruit tree whole plant comprehensively, and accuracy is not good enough.Therefore, in actual production or the research in the urgent need to a kind of can be accurately, the method for Fast Measurement defoliation of fruit trees amount and defoliation yield dynamic change.
Summary of the invention
The objective of the invention is the above-mentioned deficiency for prior art, the method for a kind of Fast Measurement fruit tree early leaf fall amount and/or defoliation yield is provided.
Purpose of the present invention can be achieved through the following technical solutions:
The method of a kind of Fast Measurement fruit tree early leaf fall amount and/or defoliation yield comprises following steps:
(1) deadwood, blade under the fruit tree tree dish are cleaned out, the assurance tree is checked and regulated clean;
(2) with net target fruit tree plant is shrouded, and used stent support, the limit net is fixed with pressure networks such as rubble or fragments of brick after hanging down to ground, in case falling leaf is coiled from tree; Net in this device had both prevented from falling leaves and had waftd from the tree dish in the dropping process, had guaranteed again normally photosynthetic, respiration of tree body, did not affect fruit tree fully and grew normally.
(3) in the time of need carrying out the field investigation statistics to the fallen leaves amount, the investigator enters netted determinator from the limit net, with counter or complicate statistics fruit tree tree dish fallen leaves quantity, record fallen leaves quantity; And the fallen leaves complete liquidation after will adding up goes out the tree dish; Again use stone fragment of brick fixed edge net, so that add up fallen leaves quantity next time;
(4) gather different times fallen leaves amount is cumulative, can calculate successively target plant fallen leaves amount and/or the defoliation yield in each period according to plant leaf total amount.
In the method for Fast Measurement fruit tree early leaf fall amount of the present invention and/or defoliation yield, bird prevention net or fishing net are selected in described network optimization, and the netting twine thickness is 400d or 800d, mesh 30mm or 45mm.
In the method for Fast Measurement fruit tree early leaf fall amount of the present invention and/or defoliation yield, described support is the simple rack of bamboo pole or branch one class.
In the method for Fast Measurement fruit tree early leaf fall amount of the present invention and/or defoliation yield, the fallen leaves of the fruit tree tree dish of statistics fallen leaves on tree disk area soil, also comprise the fallen leaves that are suspended in net inwall and the weeds in the step (3).
Beneficial effect
The method of mensuration defoliation of fruit trees quantity provided by the present invention and defoliation yield has the following advantages:
1 using method of the present invention is simple, convenient, fast.Determinator only needs the grids such as bird prevention net or fishing net; The simple rack such as bamboo pole, branch, stone or fragment of brick, counter, these materials are from the life articles for daily use, and it is simple and convenient to draw materials.And the fallen leaves quantity of directly adding up in the netted determinator gets final product, and can finish in 30 minutes, and conventional method needs 60 minutes, so this method is quick, and can individual separate operaton.
The accuracy of 2 data that the present invention surveys is high.Conventional method is to randomly draw 4～10 in peripheral branch at fruit tree plant different directions, the difference listing mark, the fruit tree early leaf fall quantity of investigation blade amt and different times, then early leaf fall amount or the defoliation yield of statistics fruit tree obtain fallen leaves amount and defoliation yield that mean value represents the fruit tree whole plant.And the direct statistics of method of the present invention is exactly fallen leaves amount and the defoliation yield of fruit tree whole plant, and error is very little, and is all more accurate than the method for any mensuration volume of fruits in the past.
3 the present invention are fit to directly measure the dynamic change of defoliation of fruit trees rate and fallen leaves amount, device only need be laid once, do not need again to settle, avoided the error that causes because of branch difference in traditional fruit tree tracer method, this dynamically all has important practical value for the research defoliation of fruit trees, for the defoliation of fruit trees dynamic research is laid a good foundation.
4 generalizations of the present invention and application are very strong.The present invention not only can measure defoliation of fruit trees amount and defoliation yield, also can be used for measuring the dynamic change of other crop fallen leaves quantity, chooses suitable net device according to actual conditions, then can measure fallen leaves quantity, therefore, has boundless application prospect.
