Description

Technical Field

[0001] The invention relates to the technical field of Scrophularia ningpoensis planting and management, and in particular to a management test method for increasing the yield of Scrophularia ningpoensis. Background Art

[0002] Scrophularia has the effects of nourishing yin and reducing fire, reducing swelling and detoxifying. Its medicinal materials come from the dried rhizomes of the perennial herb Scrophularia of the Scrophulariaceae family. The prescriptions included in the pharmacopoeia include Kouyanqing Granules, Pediatric Cough Syrup, Pediatric Baotaikang Granules, Pediatric Yanbian Granules, Kaiguang Fuming Pills, Tianwang Buxin Pills, Wufu Huadu Pills, Zhisou Huatan Pills, Neixiao Ruola Tablets, Niuhuang Jingnao Tablets, Niuhuang Qinggong Pills, Guashuang Tuireling Capsules and 73 other prescriptions. Scrophularia is a traditional bulk medicinal material in my country with important medicinal value.

[0003] However, in the process of Scrophularia cultivation, due to the influence of various factors, such as soil conditions, climate environment, field management, etc., its yield and quality are often difficult to reach the ideal level. Therefore, the development of an effective management test method for increasing Scrophularia yield is of great practical significance for improving the yield and quality of Scrophularia and meeting market demand. In view of this, we propose a management test method for increasing Scrophularia yield. Summary of the invention

[0004] The main purpose of the present invention is to provide a management test method for increasing the yield of Scrophularia ningpoensis, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the management test method for increasing the yield of Scrophularia ningpoensis proposed by the present invention comprises the following steps:

[0006] S1. Select fields with consistent soil, water and fertilizer conditions for the test;

[0007] S2, sowing the Scrophularia ningpoensis seed buds and treating the seeds before sowing;

[0008] S3. Apply fertilizers reasonably during the specific growth period of Scrophularia;

[0009] S4. Carry out routine field management of Scrophularia ningpoensis;

[0010] S5. Control diseases and insect pests on Scrophularia;

[0011] S6. Conduct detailed field records of the experimental Scrophularia;

[0012] S7. Accurately record the growth period of the experimental Scrophularia;

[0013] S8. Harvest, process and record.

[0014] Preferably, in step S1, the planting field is divided into zones, and a plurality of treatment test areas are set up, and each test area is not repeated. When selecting the field, deep, loose, fertile, and well-drained sandy loam is selected for planting. It is not suitable to plant in low-lying land and heavy clay soil with poor drainage. Before harvesting, the soil needs to be deeply plowed, and after being finely raked and leveled, a ridge 25 cm high and 130 cm wide is formed. Such soil conditions and ridge specifications are conducive to the growth and development of Scrophularia ningpoensis, and provide a good foundation for increasing production.

[0015] Preferably, in step S2, the Scrophularia ningpo seed buds are sown, and the seeds are treated before sowing to select disease-free, thick, with few side buds, more than 4 cm long, and weighing more than 15 g white or white-pink seed buds; the seed buds with cracked bud scales, many forks, small, shriveled and lifeless are removed. The quality of the seed buds in production has a great influence on the yield and quality of Scrophularia ningpo.

[0016] Preferably, in step S3, fertilization includes application of base fertilizer and topdressing. The application of base fertilizer is combined with land preparation. 300kg to 400kg of organic fertilizer and 50kg of calcium magnesium phosphate fertilizer are applied per mu, and soil is covered after planting.

[0017] Preferably, in step S3, topdressing is carried out when the seedlings are all grown, 15kg-20kg of ammonium bicarbonate is applied per mu, 10kg of urea is applied per mu when the seedling height is above 30cm, and after topping, 100kg-150kg of organic fertilizer and 15kg of superphosphate are applied per mu, mixed and spread beside the plants, and soil is cultivated after application. The main indicators of organic fertilizer are organic matter 52%, N, P2O5, and K2O contents are 4.3%, 9.2%, and 11.8% respectively, and the main indicators of nitrogen, phosphorus, and potassium ternary compound fertilizer are N, P2O5, and K2O 20% each. Reasonable fertilization can provide the nutrients required for the growth of Scrophularia ningpoensis, promote its growth and development, and thus increase yield.

[0018] Preferably, in step S4, conventional field management is performed on Scrophularia, and inter-row cultivation and weeding should be carried out in time during the seedling stage, but not too deep to avoid damaging the roots. Topdressing is required 1 to 2 times before the plants are sealed in ridges. Fertilizer is applied by digging holes or shallow trenches between the plants. While topdressing, the soil collapsed under the ridge is cultivated to the base of the plants. This can protect the growth of sub-buds, is conducive to root expansion, and plays a role in fixing the plants and preventing lodging. In addition, it can also maintain humidity, resist drought and retain nutrients. If the drought is severe, water should be applied in time, but the accumulated water needs to be removed in time during the rainy season to reduce the rot of the roots. Scientific field management can create a good growth environment for Scrophularia, reduce the occurrence of diseases and insect pests, and improve yield and quality.

[0019] Preferably, in step S5, diseases and insect pests are controlled on Scrophularia, such as leaf spot, white rot, and cotton spider mite. Leaf spot begins to occur in mid-April, and the disease is serious in hot and humid seasons. Brown spots first appear on the lower leaves of the plant. In severe cases, the leaves die. The control methods include cleaning the field, crop rotation, and spraying 1:1:100 Bordeaux mixture at the initial stage of the disease. The onset time of white rot is the same as that of leaf spot, and it mainly harms the roots. The control methods include crop rotation, pulling out diseased plants, and disinfecting the diseased holes with lime water; soaking in 1000 times diluted 50% thiophanate-methyl for 5 minutes, and then planting after drying. Cotton spider mite begins to harm leaves in June. The control methods include cleaning the field, spraying with 1000 times diluted 20% amitraz at the initial stage, and avoiding crop rotation with cotton or planting on adjacent plots. Timely and effective disease and insect pest control can reduce the harm of diseases and insect pests to Scrophularia, ensure the normal growth and development of Scrophularia, and thus improve yield and quality.

[0020] Preferably, in step S6, detailed field records are made for the experimental Scrophularia, recording weather conditions, fertilization and spraying time, dosage, etc., and also recording the occurrence of diseases and insect pests, so as to take corresponding management measures in time, such as using the tropism of pests, selecting frequency-vibration insecticidal lamps or hanging yellow sticky insect boards for trapping and killing. The insecticidal lamps should comply with the provisions of GB / T24689.2. The lamp hanging time is from early May to late October. The lights are not turned on on rainy days. The yellow sticky insect boards (specifications 20cm×25cm or 25cm×30cm) are hung in an amount of 30 to 40 per mu, 15cm to 20cm away from the base of the Scrophularia inflorescence. Detailed field records are helpful to timely discover problems and take corresponding measures to ensure the smooth progress of the experiment and the accuracy of the data.

[0021] Preferably, in step S7, the growth period of the experimental Scrophularia ningpoensis is accurately recorded, mainly the seedling period, flowering period, maturity period, etc., and the start and end time of each growth stage are recorded in detail. Accurately recording the growth period can understand the growth and development process of Scrophularia ningpoensis and provide a reference for subsequent management and research.

[0022] Preferably, in step S8, the roots are harvested, processed and recorded, and graded according to the root type, and the agronomic traits of the Scrophularia are statistically analyzed, mainly the plant height, root length, root diameter, single plant yield, etc. are measured to obtain the test result data, and the quality indicators of the Scrophularia roots are measured, such as the contents of verbascoside, angloside C, harpagoside, harpagoside, cinnamic acid, etc. The effect of the test method can be evaluated by the statistics of agronomic traits and the determination of quality indicators, providing a scientific basis for increasing the yield and improving the quality of Scrophularia.

[0023] The present invention provides a management test method for increasing the yield of Scrophularia ningpoensis. It has the following beneficial effects:

[0024] (1) The management test method for increasing the yield of Scrophularia ningpoensis can provide a good growth environment for Scrophularia ningpoensis, reduce the occurrence of diseases and pests, and improve the yield and quality of Scrophularia ningpoensis through scientific site selection, seed treatment, fertilization, field management, pest and disease control and other measures.

[0025] (2) The management test method for increasing Scrophularia yield helps to detect problems in a timely manner and take corresponding measures through detailed field records and growth period records, thus ensuring the smooth progress of the test and the accuracy of the data.

[0026] (3) The management test method for increasing the yield of Scrophularia ningpoensis can provide a scientific basis for the cultivation and management of Scrophularia ningpoensis by measuring the agronomic traits and quality indicators, further optimize the planting and management methods, and achieve increased yield and improved quality of Scrophularia ningpoensis.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 3 The present invention provides a management test method for increasing the yield of Scrophularia ningpoensis, comprising the following steps:

[0034] S1. Select fields with consistent soil, water and fertilizer conditions for the test;

[0035] In step S1, the planting field is divided into zones, and a plurality of treatment test areas are set up, and each test area is not repeated. When selecting the field, deep, loose, fertile, and well-drained sandy loam is selected for planting. It is not suitable to plant in low-lying land with poor drainage and heavy clay soil. Before harvesting, the soil needs to be deeply plowed, and after being raked and leveled, a ridge with a height of 25 cm and a width of 130 cm is formed. Such soil conditions and ridge specifications are conducive to the growth and development of Scrophularia ningpoensis, and provide a good foundation for increasing production.

[0036] S2, sowing the Scrophularia ningpoensis seed buds and treating the seeds before sowing;

[0037] In step S2, the seed buds of Scrophularia ningpoensis are sown. Before sowing, the seeds are treated to select disease-free, thick, with few side buds, more than 4 cm long and more than 15 g in weight. The seed buds with cracked bud scales, many forks, small, shriveled and lifeless are removed. The quality of the seed buds in production has a great influence on the yield and quality of Scrophularia ningpoensis. 'Zhexuan No. 1' is used as the test material. Row sowing or hole sowing can be selected. After sowing, cover with straw or leaves to keep the soil moist.

[0038] Among them, the quality of seed buds in production has a great influence on the yield and quality of Scrophularia, taking 'Zhexuan No. 1' as the test material, the types of seed buds used are classified as follows. The development status and vitality status of seed buds in production are closely related to the quality of seed buds. For this reason, a verification test was designed. The seeds were harvested and processed uniformly after the cultivation season, and the weight of commercial Scrophularia with a dry weight greater than 20g was counted. The test results showed that the quality of seed buds had a significant impact on the yield of Scrophularia, the germination rate of dehydrated seed buds was significantly reduced, the Scrophularia plants with seed bud weight less than 15g grew weakly and the yield decreased significantly, and the Scrophularia plants whose seed buds had broken dormancy (scales opened) grew weakly and the yield decreased significantly. Therefore, full dormant seed buds with a weight greater than 15g were selected as high-quality seeds for production.

[0039] Table 1 Differences in yield of commercial Scrophularia ningpoensis with different quality of buds

[0040]

[0041] Note: Lowercase letters indicate significant differences among treatments, p < 0.05;

[0042] S3. Apply fertilizers reasonably during the specific growth period of Scrophularia;

[0043] Wherein, the fertilization in step S3 includes the application of base fertilizer and topdressing. The application of base fertilizer is combined with land preparation. 300kg-400kg of organic fertilizer and 50kg of calcium magnesium phosphate fertilizer are applied per mu. The soil is covered after planting. Topdressing is carried out when the seedlings are all grown. 15kg-20kg of ammonium bicarbonate is applied per mu. When the seedling height is above 30cm, 10kg of urea is applied per mu. After topping, 100kg-150kg of organic fertilizer and 15kg of superphosphate are applied per mu. After mixing, they are spread beside the plants and the soil is cultivated after application. The main indicators of organic fertilizer are organic matter 52%, N, P2O5 and K2O contents are 4.3%, 9.2% and 11.8% respectively. The main indicators of nitrogen, phosphorus and potassium ternary compound fertilizer are N, P2O5 and K2O 20% each.

[0044] The application of farmyard manure is beneficial to the stability of soil structure, but there is a lack of standards for farmyard manure, and its use is not convenient for standardized operation; while the large-scale use of chemical fertilizers is not conducive to soil stability; therefore, this standard tends to apply organic fertilizers, combines industrial applications, designs fertilizer input experiments, uses "Zhexuan No. 1" as the test material, and cultivates according to convention. The fertilizer application characteristics are shown in the table below. Other cultivation management is uniformly carried out in accordance with the "Technical Regulations for Scrophularia Production" (DB33 / T487-2016). After planting and covering the soil, 50kg of calcium magnesium phosphate fertilizer is applied per mu. The first time, when the seedlings are in full growth, 15kg of ammonium bicarbonate is applied per mu. After the cultivation season, they are uniformly harvested and processed, and the weight of commercial Scrophularia with a dry weight greater than 20g is counted. The test verification results show that the appropriate application of organic fertilizers can obtain similar root yields as the full application of chemical fertilizers.

[0047] Note: Lowercase letters indicate significant differences among treatments, p < 0.05;

[0048] S4. Carry out routine field management of Scrophularia ningpoensis;

[0049] In step S4, routine field management is performed on Scrophularia, and inter-row cultivation and weeding should be carried out in time during the seedling stage, but not too deep to avoid damaging the roots. Topdressing is required 1 to 2 times before the plants are sealed in ridges. Fertilizer is applied by digging holes or shallow trenches between the plants. While topdressing, the soil collapsed under the ridge is cultivated to the base of the plants. This can protect the growth of sub-buds, is conducive to root expansion, and plays a role in fixing the plants and preventing lodging. In addition, it can maintain humidity, resist drought and retain nutrients. If the drought is severe, water should be applied in time, but in the rainy season, the accumulated water needs to be removed in time to reduce the rot of the roots.

[0050] S5. Control diseases and insect pests on Scrophularia;

[0051] In step S5, diseases and insect pests such as leaf spot, white rot and cotton spider mite are controlled on Scrophularia ningpoensis. Leaf spot begins to occur in mid-April and is serious in hot and humid seasons. Brown spots first appear on the lower leaves of the plant. In severe cases, the leaves die. Control methods include cleaning the field, crop rotation and spraying 1:1:100 Bordeaux mixture at the initial stage of the disease. The onset time of white rot is the same as that of leaf spot, and it mainly harms the roots. Control methods include crop rotation, pulling out diseased plants, and disinfecting the diseased holes with lime water; soaking in 1000 times diluted 50% thiophanate-methyl for 5 minutes, and then planting after drying. Cotton spider mite begins to harm the leaves in June. Control methods include cleaning the field, spraying with 1000 times diluted 20% amitraz at the initial stage, and avoiding crop rotation with cotton or planting on adjacent plots.

[0052] S6. Conduct detailed field records of the experimental Scrophularia;

[0053] In step S6, detailed field records are made for the experimental Scrophularia, including weather conditions, fertilization and spraying time, dosage, etc., and the occurrence of pests and diseases is recorded so that corresponding management measures can be taken in time, such as using the tendency of pests to kill them by using frequency-vibration insecticidal lamps or hanging yellow sticky insect boards. The insecticidal lamps should comply with the provisions of GB / T24689.2. The lamps are hung from early May to late October. The lights are not turned on during thunderstorms. 30 to 40 yellow sticky insect boards (specifications 20 cm×25 cm or 25 cm×30 cm) are hung per mu, 15 cm to 20 cm away from the base of the Scrophularia inflorescence.

[0054] S7. Accurately record the growth period of the experimental Scrophularia;

[0055] In step S7, the growth period of the experimental Scrophularia ningpoensis is accurately recorded, mainly the seedling stage, flowering stage, maturity stage, etc., and the start and end time of each growth stage is recorded in detail.

[0056] S8. Harvest, process and record;

[0057] In step S8, the roots are harvested, processed and recorded, and graded according to their root types, and the agronomic traits of the Scrophularia are statistically analyzed. If the harvest period encounters continuous sunny weather, the traditional production areas will give priority to sun drying. The roots are ventilated and dried in a sun room until they become soft and the epidermis shrinks. The roots are then graded and dried with air at a temperature of 50°C to 60°C. The roots are dried to 50% to 60% of their fresh weight. The roots are taken out and piled up for "sweating" until the inside of the roots turn black and the whole becomes soft again. The roots are covered with plastic film or straw during the "sweating" period and then dried with air at 50°C to 60°C until the moisture content is below 16%.

[0058] If the harvest period encounters rainy weather, fire drying can be used in the early stage of drying, which usually lasts for 2 to 4 days. During the first drying, the fire will be stopped twice at night, and the Scrophularia in the box will be turned up and down. After drying for 2 to 3 days, the dried small roots will be picked out, and the thick roots will continue to be dried. The temperature of the box is controlled at 40℃~60℃( Figure 1 ), and when the fresh weight reaches 50% to 60%, it is piled up to "sweate", and then continues to be dried over a low fire until the moisture content reaches less than 16%.

[0059] Comparing the water loss characteristics of medicinal materials processed by traditional processing and workshop processing, the water loss trends of medicinal materials under the two treatments are similar, and the water loss rate of medicinal materials processed in the workshop is more stable and controllable. At the same time, after the roots of Scrophularia ningpoensis were processed in the modern workshop, the content of each quality component was not significantly different from that of the Scrophularia ningpoensis samples obtained by the classical processing method, that is, the modern workshop processing can obtain Scrophularia ningpoensis samples with the same quality as the traditional processing method (Table 3). The experimental process data showed that when the processing temperature was lower than 50℃, the drying time of Scrophularia ningpoensis exceeded 30 days. Therefore, in order to take into account the quality and efficiency of Scrophularia ningpoensis processing, it is recommended to process it at a temperature range of 50℃ to 60℃. The agronomic traits of Scrophularia ningpoensis were statistically analyzed, mainly for plant height, root length, root diameter, single plant yield, etc., to obtain the test result data, and at the same time, the quality indicators of Scrophularia ningpoensis roots, such as verbascoside, angloside C, harpagoside, harpagoside, cinnamic acid, etc., were determined.

[0060] We have practiced production in Pan'an County and Xianju County, the main production areas of Scrophularia ningpoensis in Zhejiang Province. Both places selected disease-free, sturdy, with few side buds, more than 4cm long, and weighing more than 15g white or white-pink sub-buds, and planted them in late December and mid-January respectively. Among them, base fertilizer is applied in combination with land preparation, with 300kg-400kg of organic fertilizer and 50kg of calcium magnesium phosphate fertilizer applied per mu. Seedling fertilizer is applied when the seedlings are full, with 15kg-20kg of ammonium bicarbonate per mu; when the seedling height is more than 30cm, 10kg of urea per mu. Autumn fertilizer is applied after topping, with 100kg-150kg of organic fertilizer and 15kg of superphosphate per mu. Shallow ploughing is carried out in time in early April when the seedlings are about 5cm; appropriate deep ploughing and weeding are carried out in mid-May; and inter-cultivation and weeding and soiling are carried out again before the seedlings are closed in late June. From the end of November to the end of December, choose a sunny day to dig, cut off the stems, cut off the roots, remove the reed heads, fibrous roots and mud, and then carry out fire-roasting and drying processing respectively.

[0061] The per-acre yields of Scrophularia ningpoensis in the two locations were 360.1±15.7kg and 376.4±15.3kg, respectively. The samples of different specifications and batches obtained were of excellent quality. The contents of index components are shown in Table 3.

[0063]

[0064] Note: There is no significant difference in the content of index components between samples obtained by traditional processing method and mechanical hot air simulation processing method.

[0065] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
