Description
Technical field
The present invention relates to plant leaf surface spray, a kind of particularly Microelement spraying agent for potato leaf surface.
Background technology
Potato（Solanum tubeosum L.）The Andes of South America is originated in, is Solanaceae Solanum perennial herb tuberous plant.Potato nutritional enriches, and yield per unit area is high, wide adaptability, strong stress resistance, storage tolerance, disease resistance are strong, and potato is the fourth-largest cereal crops in the world, paddy rice, wheat, corn are only second to, while potato or important industrial crops, its point of economic increase is higher relative to other crops.
Nearly ten years, China's Potato Industry has rapid development, and cultivated area constantly expands, and China is the maximum country of potato production area of the world, and cultivated area is 5,100,000 hm2, cultivated area accounts for 25% or so of grown worldwide area, accounts for more than the 60% of Asia cultivated area.However, China's potato level of production is also than relatively low, per unit area yield only has 14thm-2, less than the 16thm of world average level-2, the potentiality for improving potato per unit area yield are also very big, wherein an important solution route is to improve the nutritional condition of potato, pass through scientific and reasonable fertilizer application acquisition high yield, the potato of high-quality.
The yield and quality of potato is removed to be had outside the Pass with the factor such as kind, potato seed quality, soil property, field management and environmental condition, also very big with field fertilization magnitude relation.Each growthdevelopmental stage of potato, because growth and development stage is different, required nutrient is also different, in fertilising based on nitrogen phosphorus fertilizer, but answers timely and appropriate discovery to enrich middle and trace element.Trace element is very few in crop in-vivo content, its consumption also very little, but they play vital effect to growing for crops.The need for only increase nitrogen, phosphorus, the amount of application of potassium can not meet plant growth, micro- shortage is into one of key factor of limitation crop yield.
Foliage dressing is also known as foliage top dressing or foliage application, this fertilising be passed through in production frequently with a kind of fertilizing method.Foliage application can make Nutrient Absorption operating fast, soil is avoided to the fixations of some nutrients, improve plant recovery of nutrient, and dose is few, it is suitable for micro- fertile administration, obvious effect of increasing production, especially soil environment are bad, excess moisture or arid low humidity conditions, soil peracid cross the factors such as alkali and cause that Root Absorption effect is obstructed or crop is badly in need of supplementing the nutrients and during the decline of plant growth later stage Root Absorption ability, root system can be made up using foliage spray and inhale fertilizer deficiency, effect of increasing production is preferable.
Foliage dressing is fast due to infiltration rate, and effect is good, if it is possible to invent a kind of micro- spray sprayed to potato leaf surface, can play very important effect to the growth and volume increase of potato.
The content of the invention
The purpose of the present invention is to provide a kind of Microelement spraying agent for potato leaf surface regarding to the issue above, and trace element applies not enough during solving current potato growth, the problem of influenceing plant strain growth and yield.

（Unit：μmol·mg-1·h-1）
Influence of the micro- foliage spraying agent of table 11 to potato tubers cane sugar content（Unit：%）
Influence of the micro- foliage spraying agent of table 12 to potato tubers content of reducing sugar（Unit：%）
Influence of the micro- foliage spraying agent of table 13 to potato tubers content of starch（Unit：%）
Influence of the micro- foliage spraying agent of table 14 to potato tubers sucrase activity
（Unit：mg/g·h·Fw）
The micro- foliage spraying agent of table 15 is to potato tubers sucrose synthase（SS）The influence of activity
（Unit：μmolmg-1·h-1）
Influence of the micro- foliage spraying agent of table 16 to potato tubers ADPG pyrophosphorylation enzymatic activitys
（Unit：ng ATP·min-1Point）
Conclusion：As can be seen that reduced sugar, sucrose, content of starch are largely accumulated in 7~28d, blade after processing from 6~table of table 16, with stronger photosynthetic capacity, " source " organ is embodied powerful；28~49d after processing, stalk transport capacity is most strong, and reduced sugar, sucrose in blade, starch are largely exported, and reduction trend is presented in content；49~63d after processing, due to leave photosynthetic ability enhancing, fan-out capability is died down, and autophage is reduced, so reduced sugar and sucrose have accumulation phenomenon in blade.Each content of material in micro- foliage spraying agent processing, each period blade increases therewith, embodies foliage spraying agent processing to Starch synthesis and the action effect of accumulation.
Reduction trend is presented in reduced sugar, cane sugar content in 7~28d after processing, stem tuber, and the content of starch in stem tuber is in be continuously increased change；63d after processing, when content of starch reaches peak in stem tuber, content of reducing sugar is minimized value, and sucrose has been accumulated in stem tuber.Micro- foliage spraying agent processing can remarkably promote the synthesis and distribution of photosynthate, improve synthesis and the accumulation of potato tubers starch.
The activities present of invertase and Sucrose Phosphate Synthase in 7~28d after processing, blade is enhancing trend；28~49d after processing, shows as weakening change；49~63d after processing, is presented enhancing change；Before tuber expansion period, stem tuber sucrose synthase and stem tuber sucrase activity, which are also presented, to be fallen before change, later stage strong trend is presented.Before tuber expansion period, ADPG pyrophosphorylations enzymatic activity in stem tuber shows reduction trend, and increase change is presented in the middle and later periods.Micro- foliage spraying agent processing can significantly improve blade sucrase activity, blade Sucrose Phosphate Synthase activity, stem tuber sucrase activity, stem tuber sucrose synthase activity, stem tuber ADPG pyrophosphorylation enzymatic activitys, while also accelerating the synthesis and accumulation of tuber starch.
（Three）Influence of the present invention to potato yield formation
Influence of the micro- foliage spraying agent of table 17 to potato photosynthetic rate（μmol·m-2·s-1）
Influence of the micro- foliage spraying agent of table 18 to potato Chlorophyll content（mg·g-1）
Influence of the micro- foliage spraying agent of table 19 to potato root activity（μg·g-1· h-1 Fw）
Influence of the micro- foliage spraying agent of table 20 to potato yield Components
Conclusion：From 17~table of table 20 as can be seen that micro- foliage spraying agent processing can strengthen photosynthesis, Chlorophyll content, photosynthetic rate are improved.Micro- foliage spraying agent processing, the increase to tuber initiation stage potato tubers fresh weight is shallower；Rate of rise is significantly speeded after stem tuber increases the later stage and enters the starch accumulation phase, wherein it is most fast with the growth rate during starch accumulation, it is that the formation of potato yield lays the foundation.Into potato tubers harvest time, micro- foliage spraying agent can improve individual plant potato number, individual plant potato weight, accordingly increase potato yield.
