(1) Characteristics of tissue culture fruit tree seedlings

Salver Agriculture tissue culture fruit tree rootstock is produced by asexual propagation technology of inducing and subculture of axillary buds of detoxified mother plants, so it retains all the excellent genetic traits of mother plants. Because Zhongfeng Fengwo fruit tree seedlings are grown by tissue culture, the genetic differences between the plants are minimal, the consistency of the seedlings is high, the regularity of the garden is established, the tree body is well ventilated and lighted, and the trunk growth is strong and shaped It is simple and labor-saving, and the orchard is convenient for mechanized management, and early fruits can be produced in high yields. Under the growth conditions of the two-year-old apple commodity seedlings of Kuailipu, the output per acre can reach 1.3 tons in the second year after planting. According to different varieties, the output per acre can reach 4-6 tons in a few years. Under the growth conditions of the two-year-old big cherry commodity seedlings in Kuailipu, according to different varieties, the yield per acre can reach 3000 kg in a few years.

(2) Detoxification links and variety purity control

Salver Agriculture fruit tree seedlings lead the development of domestic high-quality fruit tree seedlings with high standards of "viral-free seedlings, high quality and standardization". The company ensures that our seedlings are completely detoxified by triple testing of the mother plant, semi-finished products, and final products. The non-negative mothers of the test results are destroyed immediately after discovery; during the production process, the company's virus testing laboratory and varieties The appraisal center conducts occasional virus testing on maternal sources and tissue culture bottle seedlings; and conducts random sampling of final products to ensure the purity of varieties. During the entire production process, strict monitoring and prevention of the virus vectors are carried out. Through the above standardized quality monitoring methods, every seedling obtained by the customer is guaranteed to be a high-quality virus-free tissue culture seedling.

(3) Cultivation process of tissue culture room

Salver Agriculture has the world's most advanced tissue culture laboratories and scientific research centers. It adopts advanced production equipment imported from the Netherlands and introduces high-quality maternal varieties from abroad for expansion. It provides customers with 20 million high-quality tissue culture seedlings every year. In the production process, the international advanced fully automatic medium substrate furnace is used to maximize the retention of nutrient composition and substrate consistency, so that the excellent product rate of tissue culture seedlings in the medium reaches 100%. The apple dwarf rootstocks we produce are M26, B9 and M9-T337. The female parent is from Verbeek. The large cherry rootstocks we produce are Randing 1, Randing 2, Randing 3, Jingchun 1, Jingjing Chun No. 2 and Jing Chun No. 3 are derived from the Forestry and Fruit Research Institute of Beijing Academy of Agricultural and Forestry Sciences. These detoxified axillary buds were sent to our tissue culture laboratory for testing first, and then after a series of expansion and cultivation processes of primary culture, secondary culture, rooting culture, we saw tissue culture The seedlings thrive in the cultivation room, and their growth environments all use red and blue LED lights, closed constant temperature and humidity air flow systems, etc. to accurately control the growth conditions required for seedling growth, so as to achieve the cultivation of quality seedlings. The tissue culture room uses the most advanced group cultivation seedling management system IVS for order management. Each bottle of seedlings has a unique code, so that the mother source, medium formula, production time, cultivation environment and production of each tissue culture seedling Personnel and other processes can be traced back to ensure absolute variety purity and quality control.

(4) Growth process of intelligent greenhouse

Apple rootstocks M26, B9 and M9-T337, large cherry rootstocks, lanting series and Jingchun series, blueberry series, pear series and other fruit tree seedlings have undergone tissue culture in the cultivation room and are planted from nutrition bottles At this time, intelligent greenhouses with automatic temperature control, sprinkler irrigation, mist and other systems are waiting for them. These rootstocks from bottle seedlings in the cultivation room to paper pot seedlings in the intelligent greenhouse are carefully taken care of by technical workers. , Radiating vitality in the paper bowl.

(5) Field planting process

After living in a smart greenhouse for up to 2 months, fruit tree rootstocks and grafted sprouts are planted in batches in the field. It is necessary to deepen the land before planting, and intensive cultivation has always been Salver Agriculture's attitude towards the land. Before planting, all the land in the garden will be mechanized and deepened. Under careful water and fertilizer management conditions, fruit tree rootstocks are waiting to be grafted in autumn and winter or the following spring.

(6) Field growth process

The grafted fruit tree seedlings are already growing in the field. The skilled workers here are under the guidance of the managers of Verbeek and Salver Agriculture to carry out the bud and sharpening work. Our workers sit on the carts developed by the company to clean up and sharpen the work, reducing the workload of the workers and improving work efficiency. After 1-2 years of hard management by Verbeek managers and skilled workers, the well-grafted fruit tree seedlings in the field have grown vigorously and healthily into millions of multi-branched one-year-old commercial seedlings and Kuilipu two-year-old commercial seedlings. This winter and the spring of the next year, we planted in our customers' modern standard orchards.

(7) The process of field seedling raising, cold storage and seedling shipment

After the leaves fall in autumn, Salver Agriculture uses an automatic tree digging machine imported from the Netherlands to raise seedlings with efficient and standardized machinery, without damaging the root system, and ensuring the survival rate of planting by customers. Millions of two-year high-quality virus-free dwarf apple seedlings can be completed from the field in just 4 weeks, and graded and bundled. The classification standards of Salver Agriculture apple seedlings are better than the European Fruit Tree Association standards. On the basis of the European standard 2A, 5A and 3A seedlings are added, and the number of branches is greater than or equal to 10 and 8 respectively. After grading and bundling, they enter the cold storage specially designed for storing seedlings according to European standards, which greatly prolongs the sleeping time of seedlings under constant temperature and humidity conditions. During the spring shipment, under extreme cold weather conditions or long-distance transportation exceeding 1,000 kilometers, it must be transported by a constant temperature truck. Before loading the vehicle, wash and disinfect the compartment and seedlings separately, place the seedlings in standardized trays and bind them firmly, use a forklift to slowly put them into the constant temperature compartment, and take the necessary moisturizing measures to ensure that the quality seedlings received by customers It is properly protected during transportation.
