Method for rejuvenating and culturing seedlings of sianchau

Abstract

The invention relates to a method for rejuvenating and culturing seedlings of sianchau, which comprises the following steps: 1, culturing a mother plant of the sianchau, namely culturing a sinachau plant which is robust without insect disease in a vigorous growth period of the sianchau; and 2, culturing the seedlings by cutting, namely from February to April of the next year, selecting good mother plants, shearing cutting wood, performing slurry dipping treatment on base parts of the cutting wood, arranging the cutting wood in a dug channel on a sianchau culturing field, covering soil to makethe length of the cutting wood exposed out of the ground half to one fourth of the total length, watering rooting water thoroughly, covering a thin film and a sunshade net to keep the soil moist, after 9 to 12 days, removing the thin film and the sunshade net, thinly watering 0.1 to 0.5 percent aqueous solution of ammonium carbonate to strengthen the seedlings, and after 15 to 25 days, digging the seedlings with the soil and transplanting the seedlings to a planting field. The method ensures that the seedlings of the sianchau have high survival rate, good quality, consistent growth in the field at a later stage, low disease rate, high yield and convenient to manage, and can greatly reduce cost, labor force investment and consumption of agricultural chemicals, and improve product quality.

Description

technical field [0001] The invention relates to a method for cultivating grass jelly, in particular to a method for growing seedlings of grass jelly. Background technique [0002] Grass jelly is an annual herb of the family Lamiaceae, and it is an important plant resource for both medicine and food. The dry sample of grass jelly contains 70% carbohydrates, about 10% total flavonoids, rich in caffeine, and It contains more mineral elements and has high medicinal value.

For example, "Guangdong herbal tea granules", currently popular products on the market such as "Wanglaoji" in Guangdong, "Heqizhen...

AI Technical Summary

Problems solved by technology

The existing grass jelly seedling raising method mainly has the deficiencies in the following aspects: one, do not raise seedlings, the old man jelly grass left in the field last year is used as the seedlings of the second year, and continues to be used as continuous cropping in the production field. tillage and planting

The disadvantages are as follows: After harvesting, the field is not turned over and sun-dried in winter, and the removal of diseased plant residues and weeds in the field will increase the source of overwintering bacteria and insects in the field, and secondly, the old man himself may be sick in the previous year. , and the land is not suitable for continuous planting, so the planting yield of jelly grass is low and the disease is serious

2. Using the old grass jelly left in the field as the cutting mother plant for the second year to cut the cuttings has the following disadvantages: weak growth, poor resistance, serious pest damage, and low yield; 3. Cuttings The operation of raising seedlings is not rigorous and scientific, causing the seedlings to carry bacteria and insect sources such as diseases and insects

4. There is no scientific management and cultivation, so the survival rate is low, the growth is weak, the resistance is poor, the pests and diseases are serious, and the yield is low
