Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a planting method for interplanting honeysuckle and safflower in sandy land. Background Art

[0002] Honeysuckle (Lonicera japonica Thunb.) is a perennial vine of the genus Lonicera in the family Caprifoliaceae. It is called honeysuckle because the color of its flowers changes from white to yellow. Both its stems and leaves can be used as medicine. It has the effects of clearing away heat and detoxifying, and evacuating wind-heat. It has high medicinal and economic value and is widely used in food, medicine, cosmetics, and breeding. In the process of planting honeysuckle, in order to reduce the cost of weeding and fertilization, the planting row spacing needs to be kept above 2.2m, which results in problems such as single planting plants, low vegetation coverage, low land utilization rate, and ecological fragility.

[0003] Safflower (Carthamus tinctorius L.) is an annual herbaceous plant of the Asteraceae family. It is an economic crop that combines medicine, oil, dye, feed, and ornamental purposes. It is widely distributed throughout the world. my country has a long history of safflower cultivation. The earliest record of safflower cultivation and medicinal use dates back to the Han Dynasty. Safflower has the effects of promoting blood circulation, relieving menstruation, dispersing blood stasis and relieving pain. It has significant clinical effects in the fields of cardiovascular disease, gynecology, orthopedics, etc. Safflower is drought-resistant, alkali-resistant, disease-resistant and barren-resistant.

[0004] Therefore, intercropping honeysuckle and safflower and using scientific planting methods is expected to achieve complementarity and synergy between the two crops and solve the problems existing in the traditional single planting of honeysuckle. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a planting method for interplanting honeysuckle and safflower in compressed sandy land.

[0016] (8) Harvesting safflower: In mid-July, when safflower is in full bloom and the top of the corolla turns from yellow to red, pick the safflower before 10 a.m. on a sunny day after the dew has dried. Spread out the picked filaments in a ventilated and dry place to dry in the shade, or use drying equipment to dry at 40-50°C.

[0017] Preferably, the trunk diameter of the honeysuckle selected in step (2) is not less than 0.5 cm.

[0018] Preferably, after the honeysuckle is transplanted in step (2), the drip irrigation tape is laid 5 to 10 cm away from the honeysuckle seedlings.

[0019] Preferably, in step (4), the balanced macro-element water-soluble fertilizer is NPK 17-17-17 water-soluble fertilizer, and the compound fertilizer is NPK 15-15-15 compound fertilizer.

[0020] Preferably, the safflower seeds in step (3) are Yumin No. 3 thornless safflower seeds.

[0021] Preferably, the method for controlling diseases and insect pests of honeysuckle in step (6) is:

[0022] Brown spot disease control: from the early stage of the disease, use 600 times of 50% carbendazim or 1000 times of 70% methyl thiophanate, spray once every 5 to 7 days, spray 2 to 3 times in a row, and stop using the medicine 15 to 20 days before the flowers are harvested;

[0027] The working principle of the present invention: The arid zone in central Ningxia is dry and rainless, and the ecology is fragile. Pressed sand planting is an unsustainable production method. After years of planting, soil desertification, vegetation degradation, ecological deterioration, soil fertility decline, and agricultural product output and quality decline, which seriously affect the ecological environment and agricultural sustainable development. Honeysuckle is a perennial vine plant with strong adversity survival ability, cold-resistant, drought-resistant, waterlogged, and salt-alkali-resistant. Honeysuckle is planted in pressed sand land, and its branches grow fast, can quickly cover the ground to form a green surface, and the vegetation coverage of the pressed sand land is significantly increased; planting honeysuckle in pressed sand land changes the phenomenon of soil fertility decline and high incidence of diseases and insect pests caused by continuous planting in pressed sand land. After planting honeysuckle in pressed sand land, the soil nutrient content is rising, the soil microbial activity is increasing, and the soil quality is significantly improved; after planting honeysuckle in pressed sand land, the per mu yield has reached 100kg by 2024, and the yield increase is very significant. After planting honeysuckle in pressed sand land, the ecological environment of pressed sand land in the arid area of ​​central Ningxia has been significantly improved, and the economic benefits are significant. Planting safflower between the rows of honeysuckle can not only make full use of land, light energy, air, water, fertilizer and other resources, increase plant coverage, improve land utilization rate, increase honeysuckle yield, and increase the chlorogenic acid content of honeysuckle, but also increase the planting area of ​​safflower, avoid competing with farmland, and increase the income of honeysuckle planting in sandy land.

[0028] The beneficial effects of the present invention are as follows: 1. Improving land utilization rate. The planting method of intercropping honeysuckle with safflower is adopted, and the planting mode is changed from one medicinal material to planting two different medicinal materials. Safflower is planted between the rows of honeysuckle, which changes the planting method of honeysuckle, changes the farming system, reduces the exposed land, increases the vegetation coverage of the sand-pressed land, and improves the land utilization rate. 2. Making full use of light energy. Intercropping honeysuckle and safflower makes the two medicinal materials form layers of height and alternate rows, which is conducive to improving ventilation and light transmission conditions, improving light energy utilization, and giving full play to the yield-increasing effect of the edge row advantage. 3. Increase fertility and reduce pests. Planting safflower between the rows of honeysuckle, the root system of safflower can increase the fertility of the soil, improve the aeration and water retention capacity of the soil, and provide more nutrients for the honeysuckle. In addition, safflower can attract some beneficial insects and other insects, and reduce the damage of honeysuckle to diseases and pests. 4. Improve quality and increase production. Interplanting honeysuckle and safflower has been shown to significantly increase the yield of honeysuckle and improve the chlorogenic acid content of honeysuckle. 5. Increase the yield of sandy land. Interplanting honeysuckle and safflower can not only produce honeysuckle products, but also produce safflower products, increasing the yield of crops in sandy land. DETAILED DESCRIPTION
