Su Tie’s tiller breeding technology
First, the delivery time: In the early spring 1-2 months.
Second, to take axillary buds: cultivated for many years of strong growth of cycads often stem base and stems sprout a lot of axillary buds. In a large number of axillary buds should be selected for more than three years or four to five leaf axillary buds for reproductive materials. Because this type of axillary bud has a high degree of lignification, contains many nutrients, and has strong adaptability, it easily roots and survives. Do not choose tender axillary buds for breeding, otherwise perishable, breeding is difficult to succeed. The budding method is to cut the axillary buds from the root connected to the mother plant with a sharp knife. Cut as little as possible when cutting. The treated axillary buds are treated differently according to whether they are rooted: For those that have already taken root, they can be directly planted in a culture medium rich in humus, well-drained, and highly air-permeable; for unrooted plants, they should be placed in a cool, ventilated place. Let it dry for 2 days to 3 days, and wait for the incision to dry before performing rooting.
Third, the reminder root: The unrooted axillary buds should not be planted directly into the humus soil, and should be planted in the prime sand. The planting depth is 1/2 of the height of axillary buds. In order to prevent the wound from decaying, the wound should be covered with plant ash, charcoal powder or sulfur powder before planting. After planting, water once to keep the sand moist, but do not collect water. After being planted, it will be placed in indoor light and maintained. A new root sprouted in about 2 months, and 1 to 2 new leaves were smoked from 3 months to 4 months.
4. Transplanting: When the new leaves are all rolled out from the roll, they should be moved into the cultivation soil for management. Otherwise, the nutrients needed for plant growth cannot be provided in Susan. The culture soil was made up of 45% of humus, 20% of mycorrhizal soil, 30% of river sand and 5% of calcium magnesium phosphate fertilizer. Do not use clay as a culture soil, otherwise the cycad will cause root rot due to poor drainage.
V. Management: The management of childbirth and reproduction of the cycads is mainly the management of illumination, water and fertilizer. In light management, the cycads, sexual pleasure light, especially in the hair must be placed in the sun, otherwise the new leaf is slender, reducing its ornamental value. But afraid of the sun exposure, in the water management, it bogey water, so the training soil should not be wet and dry, and according to the principle of "do not dry, pouring is poured" principle. Keep the soil moist throughout the growing season and spray the leaves 2 to 3 times a day in the morning and evening. In terms of fertility management, the cycads are weak and do not require high fertility. When the seedlings are applied, the pancake fertilizer is applied every month or so. In the growing season, every 30 days, a 0.3% urea liquid fertilizer, 0.2% potassium dihydrogen phosphate liquid fertilizer, or 0.1% ferrous sulfate liquid fertilizer is alternately applied.
Amino acid plays an important role in human and animal nutrition and health. It has wide use and prospect market. we are decided to develop an amino acid derivative compounds according to the company 's own personnel expertise . Currently we focus on the development of amino acid derivatives. Amino acid derivative is a compound derived from sequence of reactions by amino acid, the predecessor of the amino acid derivative is an amino acid. Under leading by Massachusetts Institute of Technology Dr. Wanghong Yao , synthesis tenology has continuous improvement, production process has continuous innovation. Our original synthesis method is on the transferring to the fermentation method , enzymatic method. Under strictly environmental pressure background, the method not only greatly reduce the pressure but also improve economic efficiency. Some of our products can reach production capacity in tons, we will take reasonable measures to try to meet the market demand , and strive to achieve on time delivery , delivery asap in timely period .
we will give you:
1. Best quality in your requirement
2. Competitive price in China market
