Problems solved by technology

[0003] Manual topping is a traditional topping method. Due to the unstructured growth characteristics of some crops, manual topping is still a common and irreplaceable topping method at present, but manual topping is labor-intensive. Low efficiency and high labor costs, especially for greenhouse planting, poor working environment, not suitable for manual work

Embodiment Construction

[0014] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments.

[0015] Such as figure 1 Shown is the main schematic diagram of the crop laser interference topping method, which includes: laser generator 1, left laser beam 2, crop 3, right laser beam 4, and crop laser interference topping method. The steps include:

[0016] 1) The laser generator (1) generates two intersecting and interfering lasers (2), (4);

[0017] 2) Control the laser generator so that the two lasers are delivered to the topping position of the crops (3);

[0018] 3) According to the physical and chemical characteristics of farming, adjust the laser power to damage the top cell tissue structure and block the upward transportation of crop nutrients.

[0019] Among them, the topping position of crops is determined according to the agronomic requirements. The laser generator generates two intersecting and interfering lasers. The two l...

Abstract

The invention relates to a laser interfered crop topping method and belongs to the technical field of crop plant protection. The laser interfered crop topping method comprises the steps that a laser generator produces two intersected and interfered laser beams; the laser generator is controlled to make the two laser beams intersected at a crop topping position; according to physicochemical properties of crops, the laser power is adjusted to damage a cell tissue structure at the topping position and block upward crop nutrient delivery, wherein the height of the crop topping position is determined according to the agricultural requirements, the laser generator produces two laser beams and is controlled to make the two laser beams intersected at the crop topping position, the two laser beams form interference at the position, a large amount of heat is dissipated to promote rise of the temperature of moisture in the cell tissue at the position, and the cell tissue structure at the topping position is damaged and upward crop nutrient delivery is blocked by adjusting the laser power. The laser interfered crop topping method achieves non-contact and damage-free crop topping trough laser interference, meets the green plant protection technology requirements and can effectively replace manual topping operation.

Description

Technical field [0001] The invention relates to a laser interference topping method for crops, belonging to the technical field of crop plant protection. Background technique [0002] Topping is an indispensable link in the cultivation of many crops, and it is also an important means to improve the yield and quality of crops. In recent years, topping technology has been widely used in the cultivation of many crops. The purpose is to break the top advantage of crops, reduce the consumption of water and nutrients by invalid buds, flowers, fruits (bells) and branches and leaves, and promote more nutrients to be transported. Fruits, so as to increase yield and quality. At present, there are mainly three types of topping technology: artificial topping, chemical topping and mechanical topping. [0003] Artificial topping is a traditional topping method. Due to the characteristics of unstructured growth of some crops, artificial topping is still a common and irreplaceable topping method...
