Abstract

The invention discloses a method for adjusting and controlling the florescence of chia. The method comprises the following steps: starting to perform short-day sunshine treatment within 30-45 days before the autumnal equinox of a chia planting year, and shading at 17:00 every day to 8:00 on a next day during the short-day sunshine treatment, wherein the shading rate is 100 percent; while the short-day sunshine treatment is performed, continuously spraying and applying 50-200 mg/L abscisic acid or 15-50 mg/L cytokinin for four times once every 7 days. According to the method disclosed by the invention, through adjusting the florescence of the chia, the chia can bud and flower one month in advance; a plant cannot meet with a frost season in the whole flowering phase, so that the yield can be improved by above 20 percent. A yield-increasing effect is better in north areas of the Yangtze River.

Description

A kind of regulate and control the salvia hispanica L florescence method

Technical field

The present invention relates to the planting technology of salvia hispanica L, particularly a kind of regulate and control the salvia hispanica L florescence method。

Background technology

Omega-fatty acid is the essential fatty acid that human body maintains various normal physiological functions, nervous system development and prevention cardiovascular disease are had pivotal role by it, the main source of current omega-fatty acid is abyssal fishes and some Sargassum, but the extra large fishy smell in product have impact on the quality of product, can only deep processing further, which thereby enhance production cost。And the salvia hispanica L (SalviahispanicaL.) that Lamiaceae Salvia belongs to is can directly eating of having been found that and one of the plant rich in omega-fatty acid。Last century end archaeology personnel's finding again salvia hispanica L, makes this ancient Aztecs and Maya have the plant of more than 3000 year plantation record to receive significant attention, obtains safe edible omega-fatty acid for the mankind and provide new approach。

Salvia hispanica L obtaining the safety food certification of U.S. FDA, CODEX enrolls in Argentina, European Union is by after food legislation, this kind obtains extensive plantation in American States and Australia, but its yield is general not high so that the market price is expensive and supply falls short of demand。For breaking the external monopolization to this resource, it was introduced from America by Agricultural University Of Hunan in 2007, obtained regeneration plant by tissue culture detoxicating。But, owing to it originates in the torrid zone, it is a kind of strict short-day plant, after the Autumnal Equinox, starts pregnant flower bud, as met with the Frost's Descent in advance, the underproduction must be caused。

Summary of the invention

The technical problem to be solved is, for salvia hispanica L when China's most area plantation, florescence and frost season meet and cause this technical problem of the underproduction, there is provided a kind of regulate and control the salvia hispanica L florescence method, make salvia hispanica L can shift to an earlier date pregnant flower bud, bloom, make plant will not meet with frost season at the whole florescence。

For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of regulate and control the salvia hispanica L florescence method, it includes within 30-45 days, proceeding by short-day sunshine treatment before the Autumnal Equinox in time planted by salvia hispanica L, during short-day sunshine treatment, 17:00 carries out shading to 8:00 next day every day, shading rate is 100%, simultaneously when short-day sunshine treatment, the basic element of cell division of the every 7 days abscisic acid spraying a 50-200mg/L or 15-50mg/L, spray 4 times continuously。

The present invention regulates and controls the method at salvia hispanica L florescence and is adapted to the CHINESE REGION beyond without the Hainan Province in obvious frost season, Guangdong Province and Yunnan Province。

Cycle regulating at sunshine when the present invention is by planting salvia hispanica L, hormone regulating and controlling, compared with the control, salvia hispanica L one month earlier pregnant flower bud can be made, bloom, result plant will not meet with frost season at the whole florescence, can improve yield more than 20%。North of Yangtze River area effect of increasing production is more preferably。

Detailed description of the invention

Embodiment one:

Within 2015, carry out contrast test, test group and matched group are set in same field, all cultivating and growing conditions are identical, test group carries out full sun in beginning on August 15 8:00 to 17:00 every day, 17:00 carries out short-day sunshine treatment to 8:00 black cloth shading next day, and in short-day sunshine treatment process, every abscisic acid (ABA) spraying a 150mg/L for 7 days。JIUYUE starts pregnant flower bud in about 11 days, until JIUYUE 24 days, plant blossom, natural conditions enter short-day, terminate short-day sunshine treatment。Matched group does not make shading treatment。Result test group is bloomed and is shifted to an earlier date 20 days than matched group, blooms many and spends neat, and owing to frost season in 2015 shifted to an earlier date than former years, matched group drops in production over a large area, and test group yield increased group increases by 40.8%。

Embodiment two:

Within 2014, carry out contrast test, test group and matched group are set in same field, all cultivating and growing conditions are identical, test group carries out full sun in beginning on August 1 8:00 to 17:00 every day, 17:00 carries out short-day sunshine treatment to 8:00 black cloth shading next day, and in short-day sunshine treatment process, every basic element of cell division (6BA) spraying a 25mg/L for 7 days。JIUYUE starts pregnant flower bud in about 1 day, to JIUYUE plant blossom on the 15th, JIUYUE 18 end of day short-day sunshine treatment。Matched group does not make shading treatment。Result test group is bloomed and is shifted to an earlier date 30 days than matched group, and test group yield increased group increases by 21.4%。

Claims

1. the method regulating and controlling the salvia hispanica L florescence, it is characterized in that including within 30-45 days, proceeding by short-day sunshine treatment before the Autumnal Equinox in time planted by salvia hispanica L, during short-day sunshine treatment, 17:00 carries out shading to 8:00 next day every day, shading rate is 100%, simultaneously in short-day sunshine treatment process, the basic element of cell division of the every 7 days abscisic acid spraying a 50-200mg/L or 15-50mg/L, sprays 4 times continuously。

2. according to claim 1 a kind of regulate and control the salvia hispanica L florescence method, it is characterised in that the method is adapted to the CHINESE REGION beyond without the Hainan Province in obvious frost season, Guangdong Province and Yunnan Province。
