Abstract
The present invention provides plant in a kind of potato primary stock production process to regulate and control method, it is characterized in that Virus-free Tube Potato Plantlets are 135~180 plants/m by density240~50 days after transplanting, when plant strain growth 30~40 ㎝ of height, 800~1000 times of liquid 45~55g/ ㎡ of healthy and strong agent is sprayed, are sprayed for the first time after healthy and strong agent 25~30 days, then spray 1200~1500 times of 65~75g/ of liquid ㎡ of healthy and strong agent.Using the present invention, potato plant height has apparent inhibiting effect, and plant is made to downgrade, and promotes the cross growth of crop, and stem section overstriking, blade thickness can be made to make the shortened internodes of plant, short strong and resistant to lodging, promotes leaf color to deepen, photosynthesis is made to reinforce.Under the conditions of potato test tube seedling is planted under high density, the knot potato grain number of unit area with Effective Regulation plant, can be improved.
Description
Technical field
The present invention relates to plant in a kind of potato primary stock production process to regulate and control method.
Background technology
The yield of potato primary stock production is determined with unit area knot potato grain number.Potato primary stock produces at present
The height of yield is mainly to be regulated and controled by the planting density of Virus-free Tube Potato Plantlets.If Virus-free Tube Potato Plantlets
Planting density is low, then ties that potato potato wedge is excessive, and unit area knot potato grain number is few, low output, if the kind of Virus-free Tube Potato Plantlets
Density in planting is high, plant excessive growth, causes lodging phenomenon serious, and pest and disease damage aggravates, and no knot potato seedling growth increases, and knot potato potato wedge is too small, unit
Area qualification potato kind knot potato grain number is also few, leads to low output.Unit area knot potato grain number is improved under the conditions of high-density planting is
One of the key technology of potato primary stock production.
Invention content
The purpose of the present invention is being directed to current potato primary stock production yields process, a kind of horse is provided
Bell potato detoxification test tube plantlet, by regulating and controlling plant height, is realized under the conditions of high-density planting and improves unit area knot potato grain number
Method.
The invention is realized in this way：Virus-free Tube Potato Plantlets are 135~180 plants/m by density240~50 after transplanting
It, when plant strain growth 30~40 ㎝ of height, sprays 800~1000 times of liquid 45~55g/ ㎡ of healthy and strong agent, sprays jade for the first time
25~30 days after rice robust element, then spray 1200~1500 times of 65~75g/ of liquid ㎡ of healthy and strong agent.
Healthy and strong agent, be using ethephon (CEPHA),2-(chloroethyl) phosphonic acid as host agent and with the compound formulation of various plants growing nutrient material composition, use
Leaf color depth is thickened in maize leaf, leaf upright short-wide, the short strong internode of plant shape is short, and polar system is flourishing, and aerial root increases.Through arduous
Research and numerous experiments find that healthy and strong agent has apparent inhibiting effect to potato plant height, plant are made to downgrade, and promote to make
The cross growth of object can make stem section overstriking, blade thickness make the shortened internodes of plant, short strong and resistant to lodging, promote leaf color
Deepen, photosynthesis is made to reinforce.It is tested through newly rolling into a ball proving ground in the institute of agricultural sciences of Lijiang County In Yunnan Province city, test variety is beautiful potato 6,
Planting density is 140 Zhu/㎡, and experimental plot area is 3 ㎡, under same Fertilization Level and management condition, using the present invention than normal
Rule production potato primary stock, unit area knot potato grain number increase by 69.17%, and design parameter refers to table 1.
Table 1：The present invention and the conventional production potato primary stock test result table of comparisons
Using the present invention, under the conditions of potato test tube seedling is planted under high density, can be improved single with Effective Regulation plant
The knot potato grain number of plane product.
Specific implementation mode
The specific technical solution further illustrated the present invention with reference to embodiment.
