Embodiment 1

[0017] Embodiment 1: the method of the present invention is planted 1

[0018] The flowering planting of passion fruit seedlings is carried out in four steps according to the time sequence

[0019] The first step of seedling cultivation: select the seeds of the fine variety Fujian No. 3 passion fruit, sowing time: October 10, 2016, sow in the greenhouse of the plastic film insulation greenhouse facility, when the temperature is lower than 10 ° C, in the original In the greenhouse, a small arch was built with bamboo slices and covered with a plastic film to keep it warm. It was transplanted to the field on March 8, 2017. When the seedlings grew to a certain stage of nutrition, that is, the seedlings were 7 months old, and the seedlings grew on the scaffolding. , with a height of 2 meters.

[0020] The second step of agronomic pruning: a total of 2 prunings. The first time, on May 3, was pruned when the main vine was 20 cm long after it was put on the shelf. 4 first-class vine...

Embodiment 2

[0024] Embodiment 2: the method of the present invention is planted 2

[0025] The first step is the same as in Example 1

[0026] The second step of agronomic pruning: a total of 2 times of pruning, the first time, after the main vine was put on the shelf on May 3, it was pruned at a length of 20 cm, and the terminal bud was wiped off about 5 cm from the top of the stem to promote the first-level vine, leaving 6 A level vine. For the second time, when the first-level vines grow to 50 cm long, they will be trimmed again, and the terminal buds will be wiped off 5 cm from the top of the stem to promote the development of the second-level vines, leaving 4 second-level vines.

[0027] The third step of water control treatment: Strictly control the water in the field for 10 days on May 14, keep the water content of the soil quality at 15%, and the degree of water control is limited to the critical wilting of the leaves, so as to make it less sprouting and limit its nutrition Grow...

Embodiment 3

[0030] Embodiment 3: the method of the present invention is planted 3

[0031] The first step to the second step are the same as in Example 1

[0032] The third step of water control treatment: Strictly control the water in the field for 6 days on May 14, and keep the soil quality water content at 15%. Growth, promote flower bud differentiation, do not apply fertilizer during water control.

[0033] The fourth step plant growth regulator and fertilization treatment: after water control treatment, after 10 days of normal management of irrigation water, that is, on May 30, spray with 15% paclobutrazol wettable powder 900 times liquid (paclobutrazol content is 0.17g / L) Apply; after spraying paclobutrazol 5 days, with 0.01% brassinolide aqua 1000 times liquid (brassin content is 0.1mg / L) and potassium dihydrogen phosphate (content ≥ 99.5%) crystal 800 times liquid (potassium dihydrogen phosphate content of 1.25g / L) mixed spraying.

[0034] Planting results: on the 15th day afte...

Abstract

The invention relates to a flower forcing method for passion fruit seedlings. The method includes the steps that 1, the seedlings are cultured until the age of the seedlings is seven months, and the length of seedling bodies is about two meters; 2, agriculture trimming is performed two times, and growth of first-level vines and growth of second-level vines are promoted; 3, with leaf critical withering being limit control, water treatment is performed for 6-10 days; 4, growth regulation and fertilizer application treatment of plants are performed,paclobutrazol is used for spraying for 5 days, and rapin and monopotassium phosphate are used for mixed spraying. Within 7-15 days after growth regulation and fertilizer application treatment, namely, buds start to appear from the fourth month after transplanting, normal blossoming and fruit bearing are realized, flowering is earlier by about three months than that in planting of common passion fruit seedlings, and the flower forcing method issimple, easy to implement, low in popularization cost and remarkable in economic benefit.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for promoting flowering of passion fruit seedlings. Background technique [0002] Passion fruit belongs to the Passiflora family, and because asexually propagated seedlings are generally used in passion fruit cultivation, they are often damaged by viruses and similar viral diseases. Virus disease has become a serious restriction factor for the development of passion fruit industry in Brazil, Australia, Peru and Taiwan Province of my country. Fujian is the earliest province in mainland China to introduce and plant passionflower. According to Xu Pingdong and others who investigated the occurrence and damage of passionflower virus diseases in Fujian, it was found that virus diseases generally occur in passionflower cultivation areas, and the incidence rate is usually 30-40. %, more than 90% in severe cases. [0003] Effectively solving the problem of passion...
