specific Embodiment approach 1

[0032] Specific embodiment one: present embodiment a kind of prolong flowering period, the method for the high-efficiency potato cross-breeding that promotes setting, specifically follow the steps to carry out:

[0033] 1. Set up an elevated net shed and install sprinkler irrigation equipment; put the nutrition bowl in the upper basin into the matrix and sit in the center of the upper part of the matrix in the lower basin. In the open space between the horizontal aisles in the shed;

[0034] The elevated net shed: the lower part is rectangular, and the height of the column is 2-2.2 meters; the upper part is arched, covered with 80-mesh mesh, and the height of the vault is 1.75-1.8 meters; the width of the bottom is 12-13 meters, and the length is 30-32 meters. meters; 3 to 4 longitudinal aisles are evenly arranged in the shed, and the length of the longitudinal aisle is equal to the length of the shed; a horizontal aisle is set every 80 to 85 cm, and the width of the horizonta...

specific Embodiment approach 2

[0041] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: the installation of sprinkler irrigation equipment described in step 1: above the interior of the elevated net shed, 3 PE water pipes with a diameter of 1 inch are set, and the distance between adjacent water pipes is 2 meters , the length of the water pipe is equal to the length of the net shed; on each water pipe, an upside-down micro-sprinkler is set at an interval of 1.5 meters; the upside-down micro-sprinkler is connected to the water pump through the water pipe, and a valve and a filter are set at the same time. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0042] Specific embodiment three: what this embodiment is different from specific embodiment one or two is: in the step 1, the nutritional bowl of the upper pot adopts a black nutritional bowl, and the specification is 16cm * 16cm, and the matrix composition in the basin is by mass ratio: black soil: peat soil: Horse manure = 1:1:1. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a method for high-efficiency potato cross breeding with florescence prolonging and fructification promoting, which belongs to the technical field of potato breeding. The method solves the technical problems of short potato florescence, less blooming, and low fructification percentage. The method comprises the following steps: 1) arranging an overhead net house, and arranging sprinkling equipment; 2) accelerating germination of the potato; 3) sowing the potato and making frames; 4) performing artificial cutting on stem tubers; 5) collecting pollen and performing emasculation; 6) performing pollination and collecting fruits; and 7) taking seeds and performing storage. The method provides more convenient, faster and effective cross breeding work for the potato, the florescence of the early mature potato can achieve 25-30 days, the florescence of the later mature potato is 30-65 days, the flowering amount is greatly increased, the labor injury is reduced, and the work efficiency is greatly increased. The method is used for high-efficiency potato cross breeding with florescence prolonging and fructification promoting.

Description

technical field [0001] The invention relates to the technical field of potato breeding. Background technique [0002] Potato flowering has a distinct diurnal cycle. The opening time of each flower is about 3-5 days. Under normal conditions, the flowering period of early-maturing potatoes lasts for 10-15 days, and the flowering period of late-maturing potatoes lasts for 10-30 days. If the potatoes are in the budding or flowering period, if the soil moisture is insufficient or the air is hot and dry, it will not only affect the reduction of pollen mother cells Splitting, pollen fertility is low, and flower buds are easy to fall off, affecting fruiting. Strengthening the assimilation of the upper part of the plant during the flowering period of potatoes and blocking the downward transport of assimilated products can effectively promote the differentiation of flower buds, prolong the flowering time, and increase the number of flowering and fruit setting rates. [0003] The "b...
