Alfalfa【scientific name】Medicago sativa Legume Alfalfa

【1】Promote early rooting and improve the survival rate

Indine Naphthalene Acetic Acid

It can promote rooting of alfalfa cuttings, shorten germination time and promote branching. About 5cm in length, 1 bud and 1 node without leaf cuttings, the base of the cuttings is dipped in 2000mg/L rooting powder liquid, and inserted into the seedbed for about 1/2 of the length. After 4 days, rooting can take place, with an average of 5 branches per alfalfa.

Indine Naphthalene Acetic Acid

150mg/L 50% indbyl naphthalene acetic acid rooting powder soaked cuttings for 1 hour, the best survival rate of cuttings rooting effect was 88.3%, 71.0% higher than the control, and had higher rooting number (3.94), root length (8.96cm) ), root effect index (0.75) and number of leaves (10.46).

【2】Increase production

Gibberellic acid

Alfalfa is a fodder and green manure crop for harvesting stems and leaves. During the growth period, 100-300mg/L gibberellic acid is used to spray the leaves. In general, 200mg/L can maximize plant height and dry and fresh weight. High concentrations can also increase stems and leaves. protein content.

Diethyl aminoethyl hexanoate

Diethyl aminoethyl hexanoate can increase the yield of alfalfa, and proper dosage can increase the output of crude protein per unit area. When alfalfa began to grow rapidly, 10 mg/L diethyl aminoethyl hexanoate was sprayed, the crude protein content of alfalfa leaves increased by 39.2% compared with the control, and the crude protein content of leaves increased from 24.37% to 26.61%, an increase of 2.24 percentage points. Compared with the control, the crude protein in the culm increased by 33.5%, and the crude protein output per unit area increased by 39.32% compared with the control, reaching a significant level. At the same time, diethyl aminoethyl hexanoate treatment increased the total amount of sulfur-containing amino acids and essential amino acids in leaves, decreased the total amount of sulfur-containing amino acids and essential amino acids in stems, and the sulfur-containing amino acids of the whole plant increased by 14.85% and essential amino acids by 13.56%. , effectively improve the nutritional quality of alfalfa.

Choline chloride

In the early flowering stage of alfalfa, spraying with 400-1000 mg/L choline chloride liquid can improve the plant height, stem diameter, branch number, single stem weight and single leaf area of alfalfa to varying degrees, and promote alfalfa. The growth of shoots can improve the dry matter yield of alfalfa; it can also increase the chlorophyll content of alfalfa, improve photosynthetic performance, promote the transport of photosynthetic products to the root system, and promote the early regeneration of alfalfa; it can also effectively increase the crude protein content of alfalfa and in vitro Dry matter digestibility, reduce neutral and acidic detergent fiber content in alfalfa, thereby improving forage quality of alfalfa.
