Description
Technical Field
The invention belongs to the technical field of crop cultivation, and particularly relates to a cultivation method for mechanically sowing and improving the lodging resistance of tartary buckwheat.
Background
Fagopyrum tataricum (Polygonaceae) Fagopyrum (Fagopyrum) plants have a long history of cultivation in China, and are one of the oldest crops cultivated in the world. The tartary buckwheat has short growth period and can adapt to cold and cool climate and barren soil; mainly distributed in the high-cold and hilly mountain areas such as Yunnan, Guizhou, Sichuan, Chongqing and Tibet in the southwest of China, and also planted in Gansu, Shanxi and Shanxi in a certain scale. The tartary buckwheat is rich in nutrition and has medicinal value, has adjuvant therapy effect on patients with diabetes, hypertension, hyperlipidemia and the like, and is a valuable crop used as both food and medicine. In recent years, the bitter buckwheat products are more and more emphasized by people, and the market demand for bitter buckwheat is increasingly increased, so that the research on the production technology of bitter buckwheat is increased, the production efficiency and the benefit are improved, and the method has important practical significance for enhancing the enthusiasm of farmers for planting bitter buckwheat and promoting the development of the special bitter buckwheat industry.
In hilly and mountainous areas, the use of large machines is limited by geographical conditions such as fluctuation of terrain, small land size, inconvenient traffic and the like. At present, the tartary buckwheat production is a extensive planting mode mainly based on broadcasting and dibbling, which seriously restricts the rapid development of tartary buckwheat in hilly and mountainous areas. Meanwhile, along with the transformation of modern agriculture, the rural labor force is sharply reduced, the traditional farming mode cannot meet the production requirement of modern tartary buckwheat, and the technical requirement of agricultural machinery and agriculture is more and more obvious. In recent years, small-sized machinery and agricultural machinery agricultural technology supporting measures for crops in the southwest area have been developed to a certain extent, and have been primarily applied to the cultivation of wheat, corn and soybean. Lodging is an important factor for restricting the yield of tartary buckwheat, the research on the lodging of tartary buckwheat is mainly focused on single-factor research on planting density, fertilizing amount, hormone treatment and the like at present, agricultural and agricultural measures of tartary buckwheat in the southwest region are blank, and the research on the influence of the mechanical sowing depth, sowing amount and fertilizing amount on the lodging of tartary buckwheat is lacked, so that the research on the agricultural and agricultural measures for resisting the lodging of tartary buckwheat has important practical significance.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a cultivation method for mechanically sowing and improving the lodging resistance of tartary buckwheat, which can effectively solve the problem that the tartary buckwheat is easy to fall during the existing cultivation of tartary buckwheat.
In order to achieve the purpose, the technical scheme adopted by the invention for solving the technical problems is as follows:
a cultivation method for mechanically sowing and improving lodging resistance of tartary buckwheat comprises the following steps:
(1) loosening the soil, and adjusting the pH value of the soil to 5.0-6.0 and the content of each nutrient component in the soil;
(2) according to the formula of 150-450 kg/hm2Applying base fertilizer according to the fertilizing amount, and then adopting a seeder at the rate of 16-50 kg/hm2The sowing amount of the seeds is 2-4 cm, and the row spacing is 0.2-0.5 m;
(3) culturing according to conventional pest and disease control until the tartary buckwheat is mature.
Further, the content of each nutrient component in the soil in the step (1) is as follows: 6.93g/kg of organic matter, 75.7mg/kg of alkaline hydrolysis nitrogen, 53.0mg/kg of available phosphorus, 158.0mg/kg of quick-acting potassium, 0.743g/kg of total nitrogen and 0.856g/kg of total phosphorus.
Further, the seeding rate in the step (2) is 33.6kg/hm2。
Further, the sowing depth in the step (2) is 3 cm.
Further onThe fertilizing amount of the base fertilizer in the step (2) is 450kg/hm2。
Further, the base fertilizer in the step (2) is a high-concentration potassium sulfate compound fertilizer with total nutrient of more than or equal to 45%.
Further, the seeder in the step (2) is a 2BSF-3A row seeder.
The invention has the beneficial effects that:
1. the seedling emergence difficulty of seeds, the growth of hypocotyl, the failure of good growth of epicotyl, weak growth of plants, poor physiological activity and the unfavorable synthesis of lignin can be caused by the over-large sowing depth; if the sowing depth is too shallow, the plant root system is not developed, the epicotyl grows too fast, the stem is slender, the cell division is fast, the physiological activity is poor, and the lignin content of the stem per unit weight is reduced; the lignin content is positively correlated with the lodging resistance of the plant, so that the highest lignin content in the plant stem can be ensured by adopting the sowing depth of 3cm on the premise of not influencing the normal growth and development of the plant, thereby improving the lodging resistance of the plant stem.
2. The method has the advantages that the method is small in fertilizing amount for soil impoverishment, fine in plants, long in second internodes, low in lignin content and easy to fall down; the fertilizer application amount is too large, the number of branches of a group is large, the ventilation performance is poor, plants are easy to overgrow, the diseases are serious, the plant height is increased, and the plants are easy to fall down and are not beneficial to fructification and yield improvement; the seeding amount is low, the effective plants in unit area are few, although the improvement of the branches has certain compensation effect, the growth period of crops can be prolonged, the grain filling and maturing time can be prolonged, and the yield is not high; over-large seeding quantity can cause the result that the plant is slender, the basal internode is fast to extend, the internode is long, the lignin content is low, and the lodging resistance is weak; therefore, the method of the invention is adopted to mechanically sow, which not only can ensure the crop yield, but also can improve the lodging resistance of the crops.
3. The growth vigor of the plants with low fertility and low seeding rate is more normal, but the population yield is low; the plants with low fertility and high seeding rate are weak, poor in ventilation and easy to fall in early stage; the high-fertility low-sowing-capacity plants grow well, are robust, have more branches, but have low yield; the plants with high fertility and high seeding rate are more and dense, the ventilation performance is poor, and the plants are easy to fall down; therefore, the plants have good growth vigor, short second internodes, high lignin content and strong lodging resistance only under the sowing quantity with reasonable fertilization level and proper sowing quantity, and can obtain stable yield and high yield.
4. The method provided by the invention can be used for seeding by adopting the seeding machine, so that the crop cultivation efficiency in hilly and mountainous areas can be improved, and the lodging resistance of crops can be improved while the crop yield is ensured.
