Embodiment 1

[0014] a) Select pinellia tubers of the same size and sow them in the field.

[0015] b) Water and fertilize according to the actual situation of Pinellia, from the beginning of May, when the Pinellia plant has 3 leaves fully expanded until the plant begins to fall, at 10 am or 4-5 pm, every 10 days Spray the methyl jasmonate solution of 0.03mmol / L once, so that all or most of the leaves of the pinellia plant are evenly covered with the methyl jasmonate aqueous solution; a total of 5 times of spraying the methyl jasmonate solution.

[0016] Results: The delay time of seedling fall was 2 days, and the yield increased by 2.07%. The total alkaloid content of Pinellia tubers increased by 6.53%.

Embodiment 2

[0018] a) Select pinellia tubers of the same size and sow them in the field.

[0019] b) Water and fertilize according to the actual situation of Pinellia, from the beginning of May, when the Pinellia plant has 3 leaves fully expanded until the plant begins to fall, at 10 am or 4-5 pm, every 10 days Spray the methyl jasmonate solution of 0.06mmol / L once, so that all or most of the leaves of Pinellia plant are evenly covered with the methyl jasmonate aqueous solution; a total of 5 times of spraying the methyl jasmonate solution.

[0020] Results: The delay time of seedling fall was 4 days, and the yield increased by 2.86%. The total alkaloid content of Pinellia tubers increased by 19.46%.

Embodiment 3

[0022] a) Select pinellia tubers of the same size and sow them in the field.

[0023] b) Water and fertilize according to the actual situation of Pinellia, from the beginning of May, when the Pinellia plant has 3 leaves fully expanded until the plant begins to fall, at 10 am or 4-5 pm, every 10 days Spray the methyl jasmonate solution of 0.1mmol / L once, so that all or most of the leaves of the pinellia plant are evenly covered with the methyl jasmonate aqueous solution; a total of 6 times of spraying the methyl jasmonate solution.

[0024] Results: The delay time of seedling fall was 6 days, and the yield increased by 3.47%; the total alkaloid content of Pinellia tubers increased by 22.48%.

Abstract

The invention discloses a method for effectively delaying sprout tumbling at high temperature and raising yield and alkaloid content of pinellia ternate. During the growing process of pinellia ternate, 0.03-0.3mmol / L jasmonic acid methyl ester aqueous solution is sprayed from an external source, so that the sprout tumbling of pinellia ternate can be delayed by at most 9 days, the yield of pinellia ternate can be raised by 2%-5%, and the alkaloid content of pinellia ternate can be raised by 6%-38%. The method is easy to implement, convenient to operate, easy for pesticide farmers to master, convenient to promote, low in investment and high in profit.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and in particular relates to the planting technology of pinellia. Background technique [0002] Pinellia ternata Breit. is a perennial herbaceous plant of Pinellia genus in Araceae. It is one of the famous Chinese medicinal materials in my country. Its tubers are used as medicine. Pinellia avoids drought, fears waterlogging, and is tolerant to shade and sun. During the summer solstice period, due to the high temperature and strong light, the respiration of Pinellia is enhanced, and the consumption of materials exceeds the accumulation of photosynthesis, resulting in the destruction of the protoplasmic structure of cells, and some wither, commonly known as inverted seedlings. . The inverted seedlings of pinellia are not only an adaptation to adverse environmental conditions, but also an effective method of asexual reproduction. However, as far as the production of Pinel...
