Description

Technical Field

[0001] The invention relates to the technical field of purple wheat planting, and in particular to a purple wheat planting method. Background Art

[0002] A large amount of natural pigments and phenolic compounds, mainly anthocyanins, accumulate in purple wheat bran. Anthocyanins are a class of water-soluble pigments widely found in plants and belong to flavonoid compounds. Both anthocyanins and phenolic compounds have good antioxidant functions. Compared with ordinary purple wheat, purple wheat has a complete range of amino acids and higher content, and higher content of carotenoids, soluble protein, crude protein, crude fiber, crude fat, vitamin C, Zn, Fe, etc. It is mainly used for processing into instant noodles, bread, cereals and other foods.

[0003] Purple wheat is sensitive to salt damage, and salinized soil is very unfavorable to its growth and development. Under salt stress, the water and nutrient balance of plants is destroyed, resulting in growth inhibition and yield reduction. Salt damage causes huge losses in purple wheat yield. Therefore, adopting reasonable salt-alkali avoidance measures to increase the emergence rate of purple wheat, ensure that the seedlings are complete and uniform, and ultimately increase yield is an important way to ensure the sustainable development of purple wheat in saline-alkali land.

[0004] According to the characteristics of water and salt movement in saline-alkali soil, "salt comes with water and goes with water", controlling soil moisture evaporation can reduce surface salt accumulation to achieve the purpose of saline-alkali land improvement. Crop straw mulching is one of the effective methods of agronomic measures to improve saline-alkali soil. Straw mulching can intercept rainwater, reduce surface runoff and inhibit surface evaporation, which is beneficial to soil water retention. It has obvious effects on saline-alkali soil, such as maintaining soil moisture, inhibiting surface salt return, and promoting crop growth and development. However, most of the straw is returned to the soil and it is difficult to cover the soil. Moreover, if the straw is not treated, it is easy to carry pathogens and insect eggs, causing pests and diseases to reduce the yield of purple wheat. In addition, when the planting amount is large, the purple wheat needs to be checked manually in the later stage, which is labor-intensive. Therefore, a purple wheat planting method is proposed to solve the above problems. Summary of the invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes a purple wheat planting method, which uses a blade needle flat puncture technology. The advantage is that fewer needles are used, and often only one needle is needed to solve the patient's problem.

[0006] A purple wheat planting method proposed by the present invention comprises the following steps:

[0007] S1: deep tillage and deep loosening were used to treat the soil;

[0008] S2: preparing purple wheat seeds, sterilizing the purple wheat seeds, and sowing the purple wheat seeds;

[0013] S7: Setting a database of each growth period of purple wheat, and comparing the regional image with the database of each growth period of purple wheat;

[0014] S8: Process the purple wheat in the corresponding planting area according to the comparison results.

[0015] In a preferred embodiment, in step S1, the deep ploughing and loosening tillage mode is to use a single plowshare of a Dyma tractor or a large excavator to plough the soil to a depth of 40-60 cm and then harrow it flat.

[0016] In a preferred embodiment, in step S2, chlorine gas generated by the reaction of sodium hypochlorite solution and hydrochloric acid solution is used to sterilize purple wheat seeds.

[0017] In a preferred embodiment, in step S3, the pH value of the straw chips is adjusted to 4-6, and the straw chips are added to a high temperature box for high temperature sterilization. The temperature of the high temperature box is set to 80-90° C. and the time is set to 30-50 minutes.

[0018] In a preferred embodiment, in step S4, the straw chips are evenly spread on the soil, and the thickness of the straw chips is set to 2-4 cm.

[0019] In a preferred embodiment, in step S5, a crawler-type weeding and pesticide spraying machine is used for weeding, a drone or a high-pressure spray watering system is used for watering, and a drone is used for fertilizing.

[0020] In a preferred embodiment, in step S6, the drone is equipped with a high-definition camera, and the purple wheat planting area is recorded by the high-definition camera.

[0021] In a preferred embodiment, in step S7, the regional image is compared with the purple wheat growth cycle database. When there is a difference between the regional image and the image at the corresponding time of the purple wheat growth cycle, an abnormal proportion of the image data is obtained.

[0022] In a preferred embodiment, the abnormal ratio of image data is marked as S i, i=1, 2, 3, 4, ..., n, n is a positive integer;

[0023] By S i The standard deviation of S is used to obtain the abnormal proportion volatility of image data. i The standard deviation of is denoted as M;

[0024] The calculation formula is: In the formula, is the average value of abnormal proportion of image data;

[0025] Set the standard deviation thresholds, marked as M1 and M2, where M1 < M2;

[0026] When M1<M<M2, the result is normal;

[0027] When M≤M1 or M≥M2, an abnormal alarm is issued.

[0028] In a preferred embodiment, when an abnormal alarm is issued, the abnormal purple wheat area will be marked to directly locate the abnormal purple wheat area.

[0029] Beneficial effects of the present invention:
