Abstract
Description
Technical Field
[0001] The invention relates to the technical field of intercropping cumin with corn, and in particular to a planting method of intercropping cumin with corn by drip irrigation under film in southern Xinjiang. Background Art
[0002] Cumin (Cuminum cyminum L.), also known as cumin (transliteration of Latin cumin) or fennel, is also called "cumin" by the people in southern Xinjiang. It is the second largest spice crop in the world after pepper.
[0003] The whole cumin (fruit) is a double hanging fruit, so the cumin seeds grown in production are strictly called fruits. They are narrow spindle-shaped or narrow and long oval, 4mm to 6mm long, about 1mm in diameter, with a grayish yellow to grayish brown surface, narrow at both ends, densely covered with white prickles, and 5 obvious longitudinal ridges. The two ends are pointed, and the top has a yellow-brown protruding column base. Each seed (fruit) produces two seedlings, and the emergence method is the cotyledon emergence type, and the ability to push the soil is weak.
[0004] The best sowing period of cumin is from late February to early March. The growth period of cumin includes: seedling stage, seedling stage, bud stage, flowering and fruiting stage and maturity stage. Among them, seedling stage: cotyledon emerges and fully unfolds, and 50% of the seedlings emerge in the whole field, generally 10 to 14 days after sowing; seedling stage: from seedling emergence to bud appearance is the seedling stage, which goes through the stages of true leaf appearance, stem formation, branching, and flower bud appearance; bud stage: from bud appearance to flower appearance is the bud stage, after which buds, flowers, and fruits enter the overlapping period, the date when the first flower appears on 50% of the plants in the whole field is the flowering period, and the period with the most flowers is the peak flowering period; flowering and fruiting stage: from flowering to yellow maturity is the flowering and fruiting stage, the first inflorescence of the plant turns from light yellow to white or pink, which means pollination is completed and fruiting, the flowering and fruiting period overlaps with the bud stage for a long time, generally lasting about 20 days; maturity period: 70% to 80% of the seeds of the plants in the whole field turn from green to yellow-green until harvest.
[0005] The best sowing period for intercropping corn under this mode is early May. The growth process of corn can be divided into the following stages: Sowing: Corn seeds begin to germinate under suitable temperature and humidity conditions, and this stage takes about 10 days; Seedling stage: Corn seeds are nurtured and take root in the soil. After germination and growth, they break through the soil and grow into tender seedlings. After thinning and weeding, they gradually grow up. This process takes about 20 days; Silking and pollen shedding stage: Corn plants grow rapidly and begin to ear and bear fruit. At this time, the corn needs sufficient nutrients and water, and timely fertilization and watering are required; After entering the flowering period, the male and female flowers of corn begin to separate, and this stage lasts about 10 days; Fruiting period: Corn kernels gradually become full and eventually mature, and this stage takes about 40 days; Harvest period: Corn leaves turn yellow, the milk line of the kernels disappears, and the water content drops below 30% before harvesting; The harvested corn is dried or air-dried to safely store moisture.
[0006] Therefore, based on the biological characteristics of cumin and corn, the laws of water and fertilizer requirements, the growth process combined with the climate, as well as the biological characteristics of cumin and the management characteristics of intercropping corn, a planting method of cumin and corn with sub-film drip irrigation was proposed, so as to efficiently utilize resources and increase the production and income of cumin and corn, thereby ensuring the domestic supply of cumin and increasing the grain production capacity in southern Xinjiang, which has become an urgent need. Summary of the invention

[0020] Furthermore, in S4, three rows of corn were planted on the mulch planted with cumin, the first row of corn was 15 cm to 17 cm away from the adjacent cumin, the row spacings of two adjacent rows of corn were 45 cm and 45 cm respectively, the row spacing of the connecting rows of corn was 50 cm, and the distance between adjacent corn plants was 18 cm to 20 cm.
[0021] Further, in S4, when dripping the first water, the dripping amount is 20m 3 / 667m 2 , and apply monoammonium phosphate 3kg / 667m with water drops 2 、Potassium humate 5kg / 667m 2 ; When dripping the second water, the dripping amount is 30m 3 / 667m 2 , and apply urea 3kg / 667m with water drops2 , monoammonium phosphate 5kg / 667m 2 , Potassium sulfate 5kg / 667m 2 ; After 10 days from the second water, drip the third water, the dripping volume is 30m 3 / 667m 2 , urea 5kg / 667m 2 , monoammonium phosphate 5kg / 667m 2 , Potassium sulfate 5kg / 667m 2 After the cumin seeds are filled and expanded, water is dripped several times, with each drip being 15m 3 / 667m 2 .
[0022] Further, in S4, after the buds appear and before the second water dripping, every 667m 2 Use 3g of 98% mepiquat soluble powder mixed with 30L of water and spray evenly; during the flowering period after the third drop of water, spray every 667m 2 Mix 5g of 98% mepiquat soluble powder with 30L of water and spray evenly.

[0027] 1. Through intercropping of corn and cumin, corn is planted before cumin rows are closed, and the management of corn can be continued after cumin is harvested until the corn has sprouted, which saves time and increases the utilization rate of soil resources. Cumin is irrigated for the third time after corn is sown, which ensures the water required for corn to sprout and increases the utilization rate of water resources.
[0028] 2. Through full-layer fertilization, the base fertilizer can be more evenly distributed in the soil, so that the plants can absorb the nutrients of the base fertilizer, thereby increasing the yield of cumin and corn; using seed dressing agents to coat the seeds before sowing can prevent and control root rot, damping-off disease and small cutworms, reduce the occurrence of dead seedlings, thereby increasing the utilization rate of soil resources and increasing yields.
[0029] 3. When sowing, reasonable spacing between rows and plants can make full use of the nutrients in the soil, avoiding plants competing for nutrients due to being too close or wasting land resources due to being too far apart.
[0030] 4. The first drip of water can promote the growth of all seedlings; controlling water and fertilizer from the beginning of the cumin seedlings to before budding can promote root development and prevent excessive growth; dripping the second water can promote branching and bud formation; dripping the third water can promote flowering and fruiting, as well as grain filling; controlling water and fertilizer after the third watering until the cumin grains are filled and swollen can ensure effective inflorescence fruiting and reduce the production of ineffective inflorescences; the combination of the above-mentioned post-sowing management methods can ensure smooth and good emergence, budding, flowering and fruiting of the plants, reduce the production of defective products in each link, and thus increase the yield of cumin.
[0031] 5. After the buds appear and before the second water drop, every 667m 2 Use 3g of 98% mepiquat soluble powder to mix with water and spray evenly. During the flowering period after the third drop of water, spray every 667m 2 The chemical control method of evenly spraying 5g of 98% mepiquat soluble powder with water can control plant growth, reduce plant height and branch length, inhibit the production of ineffective inflorescences, promote the growth of taproots, develop the root system, and enhance the ability to resist lodging; promote the increase of chlorophyll content, improve the photosynthetic efficiency of the whole plant, transport more photosynthetic products to the reproductive organs, and increase the fruit setting rate.
[0032] 6. The planting and cultivation method of the present invention is scientific and reasonable, and the operation method is simple and easy to understand. It has a great promoting effect on the industrial development of natural intercropping corn, and has creativity and high practical value. DETAILED DESCRIPTION
