Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
As shown in figure 1, the invention discloses a planting method for prolonging the leaf growing period of wheatgrass, which comprises the following steps:
step S1: monitoring a time node from a leaf growing period to a flowering period of the wheatgrass;
step S2: reducing the content of the boron element in the nutrient solution at the time node, or reducing the absorption capacity of the wheatgrass root system to the boron element in the nutrient solution;
and step S3: and continuously monitoring the state of the wheatgrass, and picking blades of the wheatgrass regularly.
Specifically, in the embodiment, at the time node from the long-leaf period to the flowering period of the wheatgrass, the long-leaf period of the wheatgrass is prolonged by reducing the content of boron in the nutrient solution or reducing the absorption capacity of the root system of the wheatgrass on the boron in the nutrient solution, so that the time for the wheatgrass to enter the flowering period is delayed, and the long-leaf period of the wheatgrass is prolonged, so that the economic benefit of planting the wheatgrass can be remarkably increased. The lack of boron element can lead to the thickening of the leaves of the wheatgrass, but the anthers and the filaments are withered, the pollen is dysplastic, the fruiting rate is low, the apical dominance is lost, and the branches are increased. In the time node, because the wheatgrass needs a proper amount of boron element to develop reproductive organs, the content of the boron element in the nutrient solution is suddenly reduced or the wheatgrass plant is added with an inhibitor for absorbing the boron element, so that the reproductive organs of the wheatgrass plant can not develop and mature, the physiological characteristics of the wheatgrass plant in a long leaf stage can be prolonged, the entering of the flowering stage is delayed, and new leaves can grow again after the leaves of the wheatgrass plant are picked, the growth state of the wheatgrass plant is continuously monitored, the wheatgrass plant is picked in time after the leaves of the wheatgrass plant are mature, the picking times of the wheatgrass leaves can be increased, and the economic benefit of the wheatgrass planting is increased.
Further, the step S1 specifically includes the following steps:
step S11: scanning and photographing the wheatgrass plants at regular time;
step S12: comparing the acquired image data with prestored wheatgrass anther and filament data;
step S13: and when the anther and the filament of the wheatgrass are detected, judging that the wheatgrass is about to enter the flowering phase.
Specifically, the growth of the wheatgrass plants is relatively slow, so that the growth state of the wheatgrass does not need to be monitored at any time, and the wheatgrass is generally scanned and photographed for about two to three hours to obtain the growth state of the wheatgrass. And (3) extracting the characteristics of the acquired image data by adopting an image recognition algorithm, and comparing the extracted characteristics with the data of the ice grass anther and the filament, wherein the data of the ice grass anther and the filament is the image data of the ice grass which is about to enter the flowering period. That is, when the extracted features are similar to the features of the agropyron cristatum anther or filament, it means that the agropyron cristatum plant is about to enter the flowering phase.
Further, the specific steps for reducing the boron element in the nutrient solution are as follows:
step S21A: adjusting the pH value of the nutrient solution to be within the range of 8.7 to 8.8;
step S22A: introducing the adjusted nutrient solution into a filter, wherein the filter is a circular sealing cylinder with an upper opening and a lower opening, and a clay filtering layer is arranged in the middle of the filter;
step S23A: pressurizing the introduced nutrient solution from above the filter;
step S24A: and adjusting the pH value of the filtered nutrient solution to 5.8-6.2 to plant the wheatgrass.
Specifically, the boron element is in an ionic state in the solution in a weakly alkaline environment, so that the nutrient solution is adjusted by the acid-base regulator, and exemplarily, the pH value of the nutrient solution is adjusted to be within a range of 8.7-8.8 by adding a low-concentration potassium hydroxide solution into the nutrient solution. Leading-in filter of nutrient solution after will modulating pH value, because many boron ions of clay have very strong adsorptivity, set up the clay filter layer in the filter middle part, from the filter upper portion with nutrient solution leading-in nutrient solution, then pressurize the nutrient solution. For example, after the nutrient solution is also injected into the upper part of the filter, the upper part of the filter is covered, and the interior of the filter is aerated and pressurized from the upper part of the filter, so that the nutrient solution can pass through the clay filtering layer more quickly by pressurization.
In another embodiment of the present invention, the specific steps of reducing the absorption capacity of the wheatgrass root system to the boron element in the nutrient solution are as follows:
step S21B: adding 3% -7% calcium carbonate solution into the nutrient solution;
step S22B: adding 2-4% calcium hydroxide solution into the nutrient solution, and adjusting pH of the nutrient solution to 5.8-6.2.
Specifically, the excessive concentration of calcium ions can inhibit the absorption of the wheatgrass plants to boron ions, both the calcium carbonate solution and the calcium hydroxide solution contain free calcium ions, the pH value of the nutrient solution is adjusted by both carbonate ions and hydroxide ions in the solution, and the pH value is adjusted to be 5.8-6.2 in the embodiment because the wheatgrass plants grow in a weak acid environment.
Further, the step S3 specifically includes the following steps:
step S31, regularly photographing the wheatgrass plants;
step S32: performing characteristic analysis on the shot picture, and extracting characteristic elements in the picture
Step S33: and determining the growth state of the wheatgrass plants according to the characteristic elements, and picking the wheatgrass in the maturation period of the wheatgrass blades.
Specifically, the wheatgrass plants are photographed at regular time, and data acquisition of images is achieved. And then, carrying out feature extraction in the acquired image data to extract feature elements in the wheatgrass plants. Exemplary feature elements include plant height, leaf size, leaf shade, etc. The growth state of the wheatgrass can be determined through the characteristic elements so as to determine whether the wheatgrass plants reach the picking standard, and when the wheatgrass plants reach the picking standard, the leaves of the wheatgrass plants are picked, so that the planting economy can be improved to the greatest extent.
Preferably, the step of picking the wheatgrass in the maturation period of the wheatgrass blades comprises the following steps:
and when the size of the ice grass blades reaches a preset size, judging the colors of the ice grass blades, picking the ice grass blades when the colors of the ice grass blades are green, and picking the ice grass blades upwards from the roots of the ice grass blades in sequence during picking.
