Warmly congratulate“Saline-alkali land alfalfa whole mechanized production technology” was listed in Shandong province, the main promotion of livestock technology


Recently, the “Full mechanized production technology of alfalfa in saline-alkali soil”, jointly compiled by Shandong General Animal Husbandry Station and Shandong Lufeng Agricultural Group Co. , Ltd. , has been listed by Shandong animal husbandry and Veterinary Medical Bureau as a 2023 technology for Shandong animal husbandry.


Since the 20th National Congress of the Communist Party of China (CPC) , under the strong leadership of the CPC Central Committee with General Secretary XI at its core, Shandong's animal husbandry has overcome multiple challenges and achieved a phased victory in supporting the revitalization of the dairy industry and the development of alfalfa cultivation, however, there is still a huge gap in forage grass, the quality of the general low status of embarrassment. “We need to build a diversified food supply system,” the 2023 said. Set up a big food concept, accelerate the construction of food, economy and feed co-ordination, agriculture, forestry, animal husbandry and fisheries, plant and animal micro-organisms, a diversified food supply system, to develop implementation plans in different areas. Construction of high-quality water-saving high-yield and stable production of forage grass production base, to accelerate the development of alfalfa and other grass industry... .. ”.


The total area of saline-alkali land and inland saline-alkali land in Binhai Province is about 6,000 hectares, of which 4,400 hectares can be used for cultivation. In recent years, the forage machinery in our country has entered the fast track of high-quality development, while the advanced imported machinery is also being introduced and applied in large quantities, at the same time, it can satisfy the whole mechanization demand of large-scale alfalfa planting in the links of alfalfa planting, disease, insect and weed control, cutting, hay modulation and silage production. In order to break the barrier of resource shortage, we should develop alfalfa industry vigorously in saline-alkali land, open up the last kilometer of the whole process of alfalfa production mechanization, and train the craftsmen in the front line of alfalfa production, shandong provincial general animal husbandry station and Shandong Lufeng Agricultural Group Co. , Ltd. jointly formulated the“Saline-alkali land alfalfa whole mechanized production technology.”.


Attached: full mechanized production of alfalfa saline-alkali technical points, suitable areas and points for attention

、技术要点 Key technical points


 (1) soil preparation technology


 1. Level. Considering the actual situation of land circulation in Shandong province, considering the factors of large-scale planting of alfalfa and the application of modern medium and large-scale machinery, it is suggested to use laser grader to carry out the operation, unit planting plot area to 20-30 mu is appropriate. After leveling operation, the surface is smooth, and the average height difference of the whole effect standard is less than 3 cm.

 3. Break up the soil. The ground shall be broken up into small pieces by means of a soil crushing machine such as a disc rake or a drive rake.


 4.To create moisture. Alfalfa seedlings are difficult to overcome irrigation or soil compaction after rain, as much as possible after sowing moisture. The way of making soil moisture is suitable to use flood irrigation, about 40 square per mu of water, when the soil surface starts to be soft and dry, to be able to carry the state of sowing machinery.


  (2) precision seeding technology

      1.播种时间。 春季播种在3月15之前(须春季地表解冻深度达到3厘米即可),秋季播种力争在10月1日之前。

 1.Sowing time. Spring sowing before March 15(spring surface thawing depth must reach 3 cm) , autumn sowing before October 1.

      2.种子处理。 种子质量要符合GB4404.1标准,播种前用高效低毒的专用种衣剂进行种子包衣或药剂拌种。

 2.Seed treatment. The seed quality should meet the GB4404.1 standard. The seed should be coated or mixed with high effective and low toxic seed coating agent before sowing.

     3.合理施肥。 每亩总施肥量:氮8公斤,磷8公斤,钾8公斤,硫酸锌3公斤,提倡增施有机肥,合理施用中量和微量元素肥料。待5叶期后每亩追施氮肥15公斤,苜蓿喜钾,建议适当多施钾肥。

 3.Reasonable fertilization. Total amount of fertilizer applied per mu: 8kg N, 8kg P, 8kg K and 3kg znso 4. More organic fertilizer should be applied and moderate and micronutrient fertilizers should be applied rationally. After 5-leaf stage, 15 kg of nitrogen fertilizer per mu should be applied.

     6.播后镇压。 一般在播后次日,用专用镇压器进行镇压。播种后镇压能保证苜蓿快速出苗及根系正常生长,提高土壤抗旱保墒能力。

 6.Post-broadcast repression. General in the next day after sowing, with a special ballast for suppression. The suppression after sowing can ensure the rapid emergence of alfalfa and the normal growth of root system, and improve the ability of soil drought resistance and moisture conservation.




 (3) post-seedling management techniques

     1.查苗补苗。出苗后及时查苗 对有缺苗断垄的地块,选择与该地块相同品种的种子,及时开沟补种。

1.Check the seedlings to make up the seedlings. Check seedlings in time after seedling emergence, and select the same varieties of seeds with the same plot of land, furrow and make up the seeds in time.


2.To strike down with a hoe. After the emergence of rain or soil compaction, hoe in time to break the compaction, conducive to warming and moisture conservation.


3.Weed control. 13% Enzodone and 5% imidazethapyr were used to control grass weeds and dicotyledonous weeds respectively. As far as possible to choose a large amount of drug, high atomization coverage of the ground walking medical equipment, unmanned aerial spraying is the secondary choice.

4.Prevention and control of diseases and pests. Leaf spot, brown spot, anthracnose, aphids, thrips, red spider and Alfalfa armyworm are common diseases and pests, timely spraying of thiophanate-methyl, imidacloprid, chloramphenicol, benzamide etc. .


 (4)the technology of Medicago sativa mechanized ensilage alfalfa ensilage is the high density compaction of Medicago sativa which has more than 45% dry matter after drying, and then the anaerobic environmental conditions are formed to restrain and kill all kinds of microorganisms and avoid corruption, in order to achieve the goal of long-term preservation, the most widely used in production is wrapped silage. Alfalfa ensilage can be divided into six steps: cutting, spreading, raking, chopping, adding silage agent and ensilage

     1.刈割。 一般在5月上旬现蕾期或初花期刈割,应尽量使用压扁割草机作业。应提前认真收集天气信息,及时掌握短期内天气预报,并综合考虑苜蓿作业面积、干草产量、质量和对应机具作业能力,确定割草时间。一般连续有3-5天的晴天即可。

1.Mowing. Generally in the first ten days of may bud or early flowering mowing, should try to use the press mower operation. The weather information should be collected in advance, the short-term weather forecast should be grasped in time, and the cutting time should be determined according to the alfalfa working area, hay yield, quality and the working ability of the corresponding machinery. Generally there are 3-5 days of continuous sunny days.

     3.搂草。 搂草前,利用快速水分测定仪测定干草含水量,搂草时如要调制干草,干草含水量一般不高于13%;如要制作青贮,则含水量不要高于55%。尽量在清晨或傍晚进行搂草作业,宜采用环形路线转大圈作业,避免转急弯。

3.Rake the grass. The moisture content of hay was measured by a rapid moisture meter before raking. When raking hay, the moisture content of hay should not be more than 13% , and when making silage, the moisture content should not be more than 55% . As far as possible in the early morning or evening raking operations, it is advisable to use a circular route to turn in large circles to avoid sharp turns.

二、适宜区域Suitable area


 This technique is suitable for application in Shandong province where the soil salt content is less than 0.3% .

三、注意事项Points for attention

      1. 抢墒情及时播种。播种时间夏末秋初8月下旬最佳,如确需春播,宜于3月初土地解冻后抢墒播种,整地前要做好杂草灭除,出苗后要做好杂草防治。

1.Grab moisture and sow in time. Sowing time in late summer and early autumn in late August is the best. If spring sowing is needed, it should be done in early March after the soil thawing.


2.Control the depth of sowing. Alfalfa seeds small, must be shallow sowing, sowing depth as far as possible not more than 2 cm.


 3.When semi-dry silage to adjust the water and add bacteria. The success rate of alfalfa semi-dry silage can be improved by determining the drying time according to the weather conditions, ensuring the moisture content between 40% and 55% , and adding proper bacteria for alfalfa silage.
