Tai 'an Guo Fu Nursery Planting and Distribution Cooperative Nursery Base is a fruit tree seedling base which is established with the approval of the industrial and commercial departments and integrates scientific research, production, breeding and promotion. Shandong institute of pomology, Shandong Academy of Agricultural Sciences and Agricultural University have selected more than 300 excellent varieties of fruit trees from abroad and at home, set up bases, picked ears from their mother orchards, and bred a number of new varieties with wide adaptability and high economic benefits. More than 4 million high-quality fruit seedlings have been bred, which ensures that the seedlings with pure varieties (which can be legally notarized) are sold all over the country and are well received by users, creating a good foundation for agricultural development and farmers to get rich.

1, walnut seedlings should be planted before and after defoliation. At this time, the walnut seedlings have been capped and basically entered a dormant state. At this time, after transplanting and before freezing, walnut seedlings are sprouting new roots, which is very beneficial to the growth in the coming year. The crown of that year can reach 4 square meters.

2. Planting before freezing. At this point, the walnut seedlings have entered a state of complete dormancy. In the process of transplanting, the seedlings are in a "dream". Transplanted seedlings germinate and take root directly after spring warming, which avoids injury and has high survival rate. In those days, the average crown reached 2-3 square meters.

3. Planting walnut seedlings in spring. At this time, the roots of saplings, whether in the nursery or in the heel, have begun to sprout. The root system will be damaged in the process of transplanting, and the seedling return is slow and the survival rate is low. The crown of that year was less than 2 square meters. Some only go back to the Miao family without a crown.

4. Plant walnut seedlings in late spring. At this time, the seedlings have taken root in the soil, and the seedlings were seriously damaged during transplanting. The survival rate of returning seedlings was less than 50%, and there was almost no crown in that year.

5. Transplanting walnut seedlings in summer. At this time, the saplings have grown new branches and need a lot of water, so it is almost difficult to survive when transplanting because of sudden lack of water.

So we often say: "Planting trees in autumn (late winter) is a dream, planting trees in spring is a disease, and planting trees in summer is fatal." In order to urge growers to plant early, we decided to sell the same seedling, whether it is big or small, whether it is 1 or 2 years old. Whoever picks up the seedlings early will have room to choose the seedlings. If you plant it late, you will have less choice.
