营造和培育沙棘林,要达到预期的目标,不讲科学经营不行,这里介绍我们的一些作法供参考。 注意保护根瘤,根瘤是沙棘生长发育必不可少的部分。起苗和栽植时,应该注意保护根系上的根瘤。有条件的地方,把苗木根系在老龄沙棘树下的土壤的泥浆中醮一下,以便接种根瘤菌,造林前每穴施农家肥4—8公斤,磷肥200—400克。造林第二年春,施氮肥,每株施尿素100—150克或碳酸氢氨200—300克。夏季施磷肥,每株200克过磷酸钙。在枝条速生期,根外喷60ppm钼酸铵溶液,可促进根瘤菌的固氮作用。
To create and cultivate seabuckthorn forest, to achieve the expected goal, not to say that scientific management will not work. Here are some of our practices for reference. Pay attention to protect nodules, nodules is an essential part of sea buckthorn growth and development. When pricking and planting, care should be taken to protect the root nodules on the root system. Wherever possible, seedlings roots in the mud under the old sea buckthorn trees in the mud in order to inoculate rhizobia, afforestation before each afforestation manure 4-8 kg, 200-400 grams of phosphate fertilizer. The second year of afforestation spring, nitrogen fertilizer, each plant urea 100-150 grams or 200-300 grams of bicarbonate. Summer phosphate fertilizer, each plant 200 g superphosphate. Rapid growth in the branches, the root spray 60ppm ammonium molybdate solution can promote rhizobia nitrogen fixation.
