Description
Technical field
The invention mainly relates to vegetable planting technology field more particularly to a kind of implantation methods for improving romaine lettuce sugar content.
Background technique
Romaine lettuce, Leaf lettuce are commonly called as, and also known as goose son dish, mark son dish, lettuce son's dish, romaine lettuce are the Vegetables in China, can
It is crisp and refreshing to eat raw, slightly sweet tea, it is full of nutrition, the hypnosis that can ease pain, weight-reducing, reduce cholesterol, treatment neurasthenia,
Diuresis promotes blood circulation, is antiviral, very popular, but many romaine lettuce are all that taste is partially bitter, and palatability is poor, bright
Aobvious to reduce romaine lettuce quality, therefore, it is necessary to a kind of implantation methods for improving romaine lettuce sugar content.
Summary of the invention
In order to make up the defect of prior art, the object of the present invention is to provide a kind of plantation sides for improving romaine lettuce sugar content
Method.
A kind of implantation methods improving romaine lettuce sugar content, comprising the following steps:
(1) site preparation is colonized: being uniformly sprinkled into fermentation fertilizer to soil, is rich in Organic nutrient and mineral element phosphorus, potassium, calcium, accelerates
Absorption and conversion of the romaine lettuce to nutritional ingredient promote the accumulation of sugar in romaine lettuce blade, and the amount of being sprinkled into is 500 ~ 600kg/ mus, will be native
Earth ploughs deeply 35 ~ 40cm, does furrow, and watering to soil moisture content is 39 ~ 40%, and romaine lettuce seedling is colonized；
(2) fertilising mentions seedling: it is long to 5 ~ 6 true leaves to romaine lettuce, the nutrition that mass concentration is 234 ~ 240mg/L is uniformly sprayed to blade
Agent solution, a small amount of salt can promote Chinese leaf on piece stomatal opening in nutritional agents, increase blade to various nutritional ingredients
Coordinate to absorb, improve organic Zn content, promote photosynthesis, promote leaf growth, increases blade sugar content, it is slightly sweet agreeable to the taste, even
Twice, interval time is 10 ~ 13 days twice for continuous sprinkling；
(3) environmental management: 1 ~ 15 day after field planting, keep soil moisture content be 32 ~ 34%, temperature be 19 ~ 20 DEG C, ambient humidity is
74 ~ 76%, shading rate is 36 ~ 40%, keeps ground moistening, and root system is avoided to rot, and shading rate is high, increases romaine lettuce seedling and fits to environment
Ying Xing promotes romaine lettuce seedling to survive, 16 days and after, soil moisture content be 43 ~ 45%, temperature be 15 ~ 16 DEG C, ambient humidity be 73 ~
75%, shading rate is 30 ~ 32%, improves soil moisture, reduces shading rate, increases illumination, enhances leaf photosynthesis, improves blade
Sugar and chlorophyll content；
(4) it adopts preceding management: adopting first 10 ~ 12 days to harvesting, daily 17:00 ~ 19:00 uniformly sprays harvesting water, fountain height to romaine lettuce
It does not drip for blade is all wet, reduces volatilization, promote absorption of the blade to nutritional ingredient, harvest in water and contain chitosan, energy
Enough to increase sweet taste in leaf nutrition protective film, antibacterial desinsection extends romaine lettuce shelf life, reduces the transport and the cost of storage of romaine lettuce.
The fermentation fertilizer of the step (1), is made of raw material from the following weight: pig manure 77 ~ 79, chicken manure 12 ~ 14, corncob
12 ~ 14, peanut vine 10 ~ 12, luffa vine 8 ~ 10, vinegar grain 8 ~ 10, shell 6 ~ 8, plant ash 6 ~ 8, saccharomycete 3 ~ 5, the fermentation fertilizer
Preparation method, by corncob, peanut vine, luffa vine, vinegar grain and shell mix after, be crushed to partial size be 4 ~ 8mm, be added pig
Excrement, chicken manure and plant ash, adjust water content be 42 ~ 44%, access saccharomycete, in 26 ~ 30 DEG C ferment at constant temperature 6 ~ 7 days, natural drying
It is 16 ~ 18% to water content, must ferment fertilizer.
The weight ratio of the saccharomycete, Pichia pastoris and saccharomyces cerevisiae is Pichia pastoris: saccharomyces cerevisiae=4 ~ 5:1.
The nutritional agents of the step (2), is made of raw material from the following weight: white granulated sugar 56 ~ 58, zinc sulfate 31 ~ 33, food
Salt 5 ~ 7, multi-vitamins 1.5 ~ 1.7, all of above raw material is added to the water, and is stirred to being completely dissolved, is obtained nutritional agents.
The multi-vitamins are animal multidimensional.
The harvesting water of the step (4), is that acetic acid is added into rice washing water, makes the volume fraction 2 ~ 3% of acetic acid, heating
After boiling, 40 ~ 50 DEG C are cooled to, chitosan is added, make the mass concentration 1.1 ~ 1.3% of chitosan, stirred to completely mixed
It is even, obtain harvesting water.
The implantation methods for improving romaine lettuce sugar content, the romaine lettuce planted.
The invention has the advantages that the implantation methods provided by the invention for improving romaine lettuce sugar content, method is simple, convenient for behaviour
Make, the content of reducing sugar of romaine lettuce is made to reach 35.31mg/g, soluble sugar content reaches 63.27mg/g, and mouthfeel is slightly sweet, tender and crisp refreshing
Mouthful, the yield and quality of romaine lettuce is improved, income is made to improve 10.3%；Enough fermentation fertilizer is added in romaine lettuce when being colonized, rich in organic
Nutritional ingredient and mineral element phosphorus, potassium, calcium accelerate absorption and conversion of the romaine lettuce to nutritional ingredient, promote sugar in romaine lettuce blade
Accumulation；When romaine lettuce it is long to 5 ~ 6 true leaves when continuous 2 sprinklings nutrition agent solution, a small amount of salt can promote in nutritional agents
Chinese leaf on piece stomatal opening increases blade and absorbs to the coordination of various nutritional ingredients, organic Zn content is made to reach 4.12mg/
100g promotes photosynthesis, promotes leaf growth, increases blade sugar content, slightly sweet agreeable to the taste；Ground moistening is kept after field planting, is kept away
To exempt from root system to rot, shading rate is high, and increase romaine lettuce seedling to the adaptability of environment, promotes romaine lettuce seedling to survive, survival rate is made to reach 100%,
After romaine lettuce young leaves is grown, soil moisture is improved, reduces shading rate, increases illumination, enhances leaf photosynthesis, improves blade
Sugar and chlorophyll content；Adopt first 10 ~ 12 days and start, daily at dusk to romaine lettuce uniformly spray harvesting water, harvesting water by rice washing water with
Chitosan is made, and pH is 5.2 ~ 5.8, can enhance the photosynthesis of romaine lettuce, promote the accumulation of Organic nutrient；It is every before harvesting
Continuous sprinkling harvesting water, reduction volatilization promote absorption of the blade to nutritional ingredient, harvest in water and contain chitosan, energy at dusk for it
Enough to increase sweet taste in leaf nutrition protective film, antibacterial desinsection extends romaine lettuce shelf life, reduces the transport and the cost of storage of romaine lettuce.
