Description
Technical Field
The invention belongs to the technical field of tree nail cutting, and particularly relates to a nail mouth controller and a method for cutting a jujube tree nail by using the same.
Background
From germination to flowering and fruit setting, the jujube trees grow branches, leaves and root systems, and also undergo flower bud differentiation, flowering and fruit setting, so that a large amount of organic nutrients are consumed. However, most branches and leaves are not grown yet, the photosynthetic capacity is not strong, and the situation that the growth and the fruiting compete for nutrients is easy to occur. If the growth of branches and leaves is not regulated in time, the jujube flowers and the jujube fruits fall off due to insufficient nutrients. Although the winter jujube trees have long flowering phase and large flower quantity, the flower and fruit dropping is serious, and the natural fruit setting rate is less than 1%. When the winter jujube tree is opened with nails at proper time, the phloem of the trunk can be cut off temporarily, and the photosynthetic products are prevented from being transported to the root, thereby supplying flowering, fruit setting and young fruit expansion in a centralized manner. Therefore, timely startup of the shell is an indispensable management measure for winter jujube management. The winter jujube needs about 60 days from blooming and fruit setting to fruit expansion and forming, so theoretically, the time from opening the nails to healing the nail openings can be preferably controlled to be more than 60 days and the smooth healing of the nail openings is ensured. Factors influencing the healing speed of the nail opening in actual production are various, namely the width of the nail opening, the strength of the tree and the like which are visible and predictable in advance; there are also previously invisible and unpredictable factors such as air temperature, air humidity, rainfall conditions, etc. after opening the nail. The width of the nail mouth in the traditional nail opening method is 5-10 mm or even wider, the specific width is difficult to control, the too narrow healing of the nail mouth can cause flower and fruit dropping to influence the fruit setting rate, and the too wide healing of the nail mouth can cause tree weakness and even dead tree. Under the existing equipment and technical conditions, if the nail mouth is healed too fast, secondary nail opening is needed, hormone and daub are needed to be coated when the nail mouth is not healed timely, the nail mouth is exposed, and the sterilization insecticide needs to be sprayed for multiple times to prevent and control insect pests such as the nail mouth insects and the like and needs to be checked regularly. In conclusion, the traditional method for managing the first jaw is faced with a plurality of uncertain factors, and is difficult to accurately control the healing time of the first jaw, so that great loss is caused, the operation is complicated, a large amount of manpower and material resources are required to be invested, the management cost of winter jujubes is greatly increased, and the difficulty is brought to the management and control of yield and quality.
Disclosure of Invention
Aiming at the problems that the mouth of a first jaw is exposed after the opening of a first jaw of winter jujube, the healing of the mouth of the first jaw is not easy to control, the yield and the quality are low and the like in the prior art, the mouth-first controller is provided, the healing time of the mouth of the first jaw is easier to control, the mouth of the first jaw is prevented from being exposed, and insects and rain are prevented; also provides a method for opening the shell of the jujube tree by using the controller, which reduces the using amount of hormone, concentrates more nutrients for the growth and development of fruits, improves the quality of the fruits and increases the economic benefit.
In order to achieve the purpose, the invention provides an nail mouth controller which comprises a long sheet and a plurality of trapezoidal sheets arranged on the long sheet, wherein a plurality of saw teeth are arranged on the outer sides of the tops of the trapezoidal sheets, a plurality of through holes and a scribing line are arranged on the long sheet, and the through holes at the two ends of the long sheet are connected through buckles.

9. A method for opening nails of jujube trees by using the nail controller of any one of claims 1 to 8, which comprises the following steps:
(1) performing nail cutting on the jujube tree by using a nail cutting device, wherein the width of a nail opening is 2.5-3.5 mm;
(2) spraying an insecticide and a bactericide on the nail mouth 5-8 days after opening the nail, and then winding the chicken intestine to enable the chicken intestine to be tightly attached to the xylem of the nail mouth;
(3) cutting an A controller which is adaptive to the thickness of branches at an A opening part along a marking line, enabling a trapezoidal thin sheet of the A controller to penetrate into the A opening and tightly press the A controller on chicken intestines, connecting through holes at two ends of the A controller by a buckle to enable the A controller to be fixed at the A opening, and enabling one side of each sawtooth to face upwards;
(4) thinning fruits after the first physiological fruit drop, and hanging one fruit for each jujube;
(5) when the highest temperature in the day is more than or equal to 26 ℃, a rotating mechanism is used for rotating the nail mouth controller for 180-540 degrees along the sawtooth direction to realize secondary nail opening;
(6) and 8, taking down the first mouth controller through the unloader in the middle ten days of the month until the first mouth is naturally healed.
10. The method of claim 9, wherein the water content of the chicken intestine in step (2) is controlled to be less than 10% by weight.
