Description

Technical Field

[0001] The invention belongs to the technical field of pepper planting, and particularly relates to a seed sowing and seedling raising method for red pepper. Background Art

[0002] Zanthoxylum bungeanum is a deciduous shrub or small tree of Rutaceae. The fruit peel is called pepper red and is known as one of the "eight major condiments". It is a common cooking seasoning and Chinese medicine ingredient in the family. Zanthoxylum bungeanum has a long history of cultivation in my country and is widely distributed. The planting area and output rank first in the world, and it has a good market development prospect. Zunyi Yinhong pepper has the characteristics of strong aroma, pure numbness, strong cold resistance, good yield, wide adaptability and high added value. It is deeply loved by consumers. It is rich in volatile oils, alkaloids, flavonoids, etc. It is not only a common condiment, but also has the effects of antibacterial, anti-inflammatory, antioxidant, warming and dispersing cold, dehumidifying and relieving pain, killing insects and detoxifying in medicine. It is often used to treat diseases such as cold pain in the abdomen, vomiting and diarrhea, and abdominal pain caused by worms. Modern research has also found that Zanthoxylum plants also have certain potential in anti-tumor and anti-cardiovascular diseases. The current market price of fresh pepper is 100-200 yuan / kg, and its economic benefits are very considerable.

[0003] Restricted by the existing seedling raising technology, the red pepper has not been able to achieve standardized, systematic and large-scale seedling raising, thus limiting the development of the industry. Seed sowing seedling breeding has the advantages of convenient operation and short cycle. The traditional seedling breeding of Zunyi Red Pepper has a low germination rate of only about 30% due to improper handling of the links such as site selection and land preparation, seed collection and drying, germination and sowing, and the lack of corresponding technical standards, resulting in a waste of red pepper seeds and increased seedling raising costs, which seriously restricts the healthy development of the red pepper industry. Therefore, a seed sowing seedling raising method for red pepper is proposed to address the above problems. Summary of the invention

[0004] The invention aims to provide a seed sowing and seedling raising method of red prickly ash, so as to solve the problem of low germination rate of prickly ash breeding in the prior art.

[0005] A seed sowing and seedling raising method of red pepper in this scheme comprises the following steps:

[0006] S1. Seed collection: Select mature trees over 5 years old. From late August to early September, place the newly harvested fruits in a well-ventilated place to dry in the shade, avoid direct sunlight, and remove the peel and impurities to obtain the seeds.

[0007] S2, seed selection: Put the pepper seeds in a container, put them in clean water with the water level 15 to 25 cm higher than the seeds, and soak them for 24 hours, filter out the seeds floating on the water surface for later use, and collect the full seeds sunk to the bottom of the container; soak the seeds floating on the water surface in the first round of seed selection for another 24 hours before the second round of selection; and then dry the selected seeds;

[0008] S3, seed treatment: alkaline water degreasing method is used to remove the oil and wax of the pepper seeds, and then rinsed with clean water for several times. The treated seeds are placed in a dry and ventilated place to air dry until no water drips, and the seed surface is kept moist;

[0009] S4. Land preparation and seedbed making: Choose a sandy loam soil with a leeward and sunny location and thick soil layer. Apply 250-350 kg of fully decomposed farmyard manure per mu before sowing, and apply 50-70 kg of diammonium phosphate or superphosphate. Plough the land to bury the farmyard manure into the tillage layer. Make a ridge with a width of 1.2 meters and a length of 10 meters, and water it thoroughly before sowing.

[0010] S5. Sowing: preferably in autumn or spring, sow 600 grams of pepper seeds per compartment, cover with 1 cm of substrate after sowing, wait for germination, and manage the buds after germination;

[0011] S6. Bag transplanting: Apply well-rotted organic fertilizer evenly on the planting ground, rake finely to obtain nutrient soil, use non-woven fabric to bag the nutrient soil and place it flat in the compartment, transplant the seedlings with 4 to 5 true leaves into the non-woven nutrient bags filled with nutrient soil, the transplanting depth is 8 to 12 cm, and water enough to establish roots;

[0012] S7. Post-management: Top dressing can be done 20 days after transplanting the seedlings. Apply water-soluble fertilizer every 15 to 20 days, and 4 top dressings are needed. Do a good job in preventing and controlling aphids and rust.

[0013] Further, in S3, a solvent is prepared by mixing alkali and water in a ratio of 3:100, and the preferred Zanthoxylum bungeanum seeds are soaked until the seeds turn from black to yellow-brown and pitting and unevenness appear on the surface;

[0014] Furthermore, in S5, 210 liters of wood husk or seedling medium are used to cover the seeds, and the covering surface is preferably 2 cm higher than the seeds.

[0015] Furthermore, in S5, each ridge is sprayed with a solution prepared by 30g of Bacillus subtilis or carbendazim and 15kg of water until the soil is moistened, and then covered with a shade net to retain moisture, and the shade net is removed in time after germination begins.

[0016] Furthermore, the concentration of the last two top dressings in S7 needs to be doubled.

[0017] Furthermore, in S5, 10 days after the seeds germinate, metalaxyl is applied to control bacterial wilt and damping-off; amino oligosaccharides are applied to control viral diseases; benzylmeconazole is applied to control leaf spot disease, and clothianidin granules are applied to control underground pests. The application is applied once a week and twice in a row.

[0018] Furthermore, when preventing and controlling diseases and insect pests in S5, foliar fertilizers such as potassium dihydrogen phosphate, glucose, and brassinolide are applied directly on the leaf surface of the seedlings. When the seedlings grow three true leaves, water-soluble fertilizers are applied until the soil is soaked. Spray once every 10 days, and apply three times.

[0019] Furthermore, the seed treatment in S5 also includes seed coating. After the seeds are washed and dried, the seed coating treatment is carried out. 1.5 kg of Zanthoxylum bungeanum seeds are mixed with 20 g of thiamethoxam to prevent root rot, bacterial wilt and underground pests. It is appropriate to treat 10-15 kg of seeds at a time. The mixture is mixed until the surface of the Zanthoxylum bungeanum seeds is completely red, and then the seeds are spread out to dry in the shade.

[0020] Timely sowing, generally in autumn or spring, is beneficial to improving the germination rate and ensuring uniformity of germination. Spring sowing is suitable for large-scale seedling cultivation.

[0021] The beneficial effects of the present invention are as follows: since the shell of the Chinese prickly ash is hard and has a thicker oily wax layer on the outer layer, it is not easy to absorb water and has difficulty in germination. The seed treatment method adopted in the present invention can effectively ensure the germination rate and survival rate of the Chinese prickly ash seeds, and the germination is uniform and early, the roots of the seedlings grow vigorously, the seedlings develop completely and robustly, and the survival rate of the planting is improved.

[0022] Compared with the prior art, the present invention effectively solves the problems of low seed germination rate, seed waste and excessively high labor cost in the development of the pepper industry. By breeding pepper seedlings through this method, the seed germination rate can reach 80%, the seedlings have a well-developed root system, and the survival rate after transplanting can reach more than 95%, thereby improving production efficiency and reducing production costs.

[0023] The present invention also provides a seed soaking container, which is used for soaking the seeds in step S2. The container includes a salvaging mechanism, a driving mechanism, and a soaking bucket of a cubic structure. The salvaging mechanism includes a connecting shaft and a salvaging body installed on the connecting shaft. The connecting shaft is located above the soaking bucket. The salvaging body is located below the water surface when salvaging seeds floating on the water surface. The driving mechanism is used to drive the salvaging mechanism to move above the soaking bucket.

[0024] Furthermore, the driving mechanism includes two lead screws and a power mechanism that drives the two lead screws to rotate synchronously. Both lead screws are connected to nut seats, and both ends of the connecting shaft are connected to the nut seats through connecting blocks.

[0025] Furthermore, the salvage body is an arc-shaped plate structure, and a plurality of filter holes are evenly distributed on the salvage body. There are a plurality of salvage bodies, and the plurality of salvage bodies are evenly distributed axially on the outer wall of the connecting shaft. One end of the connecting shaft is connected to a motor, and the motor is installed on one of the nut seats; the salvage mechanism also includes a net bag, the opening of which is supported by a rectangular frame, and the opening is located below the area where the concave surface of the salvage body faces downward, and the two ends of the rectangular frame are connected to the connecting block through a support frame and avoid the moving track of the salvage body. A plurality of soft brush wires are evenly distributed on the lower edge of the rectangular frame, and when the salvage body passes through the soft brush wires, the seeds adhered to the salvage body are brushed off into the net bag.

[0026] The seeds are placed in a soaking bucket and soaked in water. When the seeds floating on the water surface are filtered out, the driving mechanism is started to slowly move the salvaging mechanism from one end to the other end on the soaking bucket, that is, when the power mechanism drives the two lead screws to rotate synchronously, the nut seat moves on the lead screw, and the connecting shaft connected to the nut seat follows the movement. During the movement of the salvaging mechanism, the salvaging body intercepts the floating seeds and then salvages them. Specifically, the motor is started to drive the connecting shaft to rotate, and a number of salvaging bodies alternately enter the water, and the inner concave surface of the arc-shaped salvaging body faces the floating seeds, so that the floating seeds can be salvaged. When the salvaging body with seeds passes above the opening of the net bag, the seeds fall into the net bag under the action of gravity, and the seeds adhering to the salvaging body are brushed off into the net bag when the salvaging body passes through the soft brush wire.

[0036] Embodiment 2: A method for raising seedlings of red pepper by sowing seeds, comprising the following steps:

[0037] S1. Collection of improved seeds: Select mature trees that are healthy, free of pests and diseases, and mechanical damage, and are more than 5 years old. The best time to harvest is generally from late August to early September. Seeds are harvested when the peel changes from green to reddish brown or purple-black. Newly harvested fruits are spread out to dry for 3-5 days at a temperature below 20°C, avoiding direct exposure to the sun. After drying, tap the seeds with a small wooden stick and rub them with your hands to thresh the seeds;

[0038] S2, seed selection: The collected pepper seeds are selected by water selection, the threshed seeds are collected in a plastic basin or bucket container, and soaked in clean water with the water level 20 cm higher than the seeds for 24 hours, stirring once every 4-5 hours, and then the seeds floating on the water surface are filtered with a sieve, and the full seeds sunk to the bottom are collected; the seeds floating on the water surface in the first round of seed selection are soaked again for 24 hours for the second round of selection; and then the selected seeds are dried;

[0039] S3. Seed treatment:

[0040] Remove the wax layer: Use washing powder and detergent or alkali and water in a ratio of 3:100 to prepare a solvent, soak the selected pepper seeds for 10 minutes, and use a micro-stirrer placed above and below the container to stir continuously during the soaking process until the seeds turn from black to yellow-brown, and pitting and unevenness appear on the surface;

[0041] Seed cleaning: rinse the pepper seeds with clean water to remove the wax layer, and rinse off all grease, detergent and impurities in the shell. Rinse 3-5 times until the water is clear, then place the rinsed seeds in a dry, ventilated room or under a shed to dry naturally until no water drips, keeping the surface of the seeds moist;

[0042] Seed coating: Mix 20g of thiamethoxam·chloranil·frost-methyl with 1.5kg of pepper seeds to prevent root rot, bacterial wilt and underground pests. It is advisable to treat 10-20kg of seeds at a time. Mix until the surface of the pepper seeds is completely red, and then spread them out to dry in the shade.

[0043] S4. Land preparation and seedbed preparation:

[0044] Fertilization and plowing: Choose a sandy loam soil with thick soil layer and leeward and sunny. Apply 300kg of fully decomposed farmyard manure per mu, and 50kg of diammonium phosphate or superphosphate. Spread the fertilizer evenly and bury the farmyard manure into the tillage layer through plowing.

[0045] Seedbed preparation: Dig out and prepare the soil to prepare the seedbed according to the specifications of 1.2m wide and 10m long. The bed surface should be in the shape of a turtle back. Leave a 50cm wide ditch between each bed. Spray Bacillus subtilis or carbendazim solution on the bed surface for sterilization 5-7 days before sowing. Spray until the bed surface is wet.

[0046] S5. Sowing at the right time: Sichuan pepper can be sown all year round. In the southwest region, autumn or spring sowing is generally chosen, which is conducive to improving the germination rate and ensuring the uniformity of germination. Before sowing the seeds, evenly spread 140L of wood bran or seedling medium on each compartment. Mix the coated seeds with coal ash or dry fine sand and evenly sow them on the compartment surface. Sow 600g of Sichuan pepper seeds on each compartment, cover the seeds with 210L of wood bran or seedling medium, and the cover surface should be 2cm higher than the seeds. Then spray each ridge with a solution prepared by 30g of Bacillus subtilis or 15kg of carbendazim in water until the soil is moist. Finally, cover with a shade net to keep moisture. When the daytime temperature is higher than 25℃, the Sichuan pepper seeds can germinate in 20 days; when the temperature is lower in autumn, they will begin to germinate in 30-45 days, and the shade net should be removed in time after germination.

[0047] Ten days after the emergence of seedlings, timely control of diseases and insect pests can be carried out. Metalaxyl and carbendazim can be used to control bacterial wilt and damping-off; amino oligosaccharides can be used to control viral diseases; benzylmethionine can be used to control leaf spot; clothianidin granules can be applied to control underground pests, once a week, and twice in a row. When controlling diseases and insect pests, foliar fertilizers such as potassium dihydrogen phosphate, glucose, and brassinolide can be applied directly on the leaf surface of the seedlings. When the seedlings grow three true leaves, American high calcium potassium treasure can be applied until the soil is wet, and sprayed once every 10 days, and three times can be applied;

[0048] S6. Bag transplanting: Use a micro-tillage machine to break up the dry soil, apply 500kg of decomposed organic fertilizer per mu, stir evenly and rake finely, then use 15cm×16cm non-woven fabric to bag the nutrient soil and place it flat in the compartment, place 6 nutrient bags in each row, fill the gaps between the nutrient bags and around the compartment surface with soil, then use steel pipes to build a sunshade net 2 meters above the ground, with 50cm between each compartment as an aisle. Transplant the seedlings with 4-5 true leaves into the non-woven nutrient bags filled with nutrient soil, the transplanting depth is about 10cm, and water enough to establish roots;

[0049] S7. Post-management: Top dressing can be done 20 days after transplanting the seedlings. Apply American high-calcium potassium water-soluble fertilizer once every 15 days, and 4 top dressings are needed. The last two times require 2 times the concentration. At the same time, do a good job in preventing and controlling diseases and pests such as rust, powdery mildew, sooty mold, aphids, etc., weed regularly, ensure the normal growth of seedlings, and increase the seedling rate.

[0050] Comparative Example: The difference from the embodiment is that:

[0051] Seed coating was omitted in S3;

[0052] The sowing method in S5 is to choose fertile loam or sandy loam land that is convenient for irrigation to ensure the growth and survival rate of seedlings; before sowing, apply 4500kg~5500kg of high-quality farmyard manure, 40kg~60kg of ammonium carbon, and 40kg~60kg of phosphate fertilizer per mu, and deep plow immediately, then prepare the land and make ridges with a width of 1~1.2m, and water thoroughly once before sowing; when sowing, sow according to the row spacing of 20~30cm, the sowing amount per mu is 5~7kg, and after sowing, cover the soil with 0.6~0.8cm, and cover the ridge with 2cm of grass or sand to keep it moist.

[0053] Table 1, comparison of the emergence rate and survival rate of red pepper seedlings in the embodiment and the comparative example technology

[0054] Example Comparative Example Seedling rate (%) 83 60～75 Survival rate (%) 95 70～90

[0055] Compared with the prior art, the present invention effectively solves the problems of low seed germination rate, seed waste and excessively high labor cost in the development of the pepper industry. By breeding pepper seedlings through this method, the seed germination rate can reach 80%, the seedlings have a well-developed root system, and the survival rate after transplanting can reach more than 95%, thereby improving production efficiency and reducing production costs.

[0056] like Figure 3 As shown, the red pepper seedlings cultivated by the method described in the embodiment show significant growth advantages. The seedlings are not only lush and dense, but also have strong and strong stems, regular growth shapes, and evenly distributed leaves. Such seedlings are transplanted to enhance the vitality and health of the pepper tree. The presentation of this growth condition is due to the cultivation method described in the embodiment. The method involves the selection and treatment of seeds; fine management of soil conditioning, irrigation and fertilization, pest and disease control, etc., so as to ensure that the red pepper seedlings can obtain sufficient nutrients and a suitable growth environment during the growth process to improve the germination rate and survival rate of the seeds. The conditioning of soil and fertilization is conducive to the soil environment for the growth of red pepper seedlings to ensure that the seedlings can obtain sufficient nutrients and water.
