Method for improving grafting survival rate of potato and pepper

Abstract

The invention provides a method for improving a grafting survival rate of potato and pepper. The method comprises the following steps: step one, selecting the potato as root stock, selecting the pepper as scion, and raising seedlings of the cion in 30-60 days before raising seedlings of the root stock; step two, removing all branch buds and leaves when the height of potato stock seedlings is 25cm; step three, obliquely cutting basal parts of seedling stems by 45-degree angles and taking the pepper scion; step four, treating the pepper scion for 30 minutes via an activation formula and grafting; step five, fixing the potato root stock and the activated pepper scion via a grafting clip, thus finishing grafting; and step six, cultivating the grafted pepper seedlings under the conditions that the temperature is 25-28 DEG C and the air humidity is 70-95%. Through the method for improving the grafting survival rate of the potato and the pepper, yield and benefit of stereo-cultivation of two vegetables above the ground and under the ground can be redoubled; the grafting survival rate of the pepper and the potato is increased from 0.0% to 86.0%; the production cost is reduced by more than 86%; the industrialization of a grafting technique of the potato and the pepper is achieved.

Description

technical field

[0001] The invention relates to the technical field of modern vegetable cultivation, in particular to a method for the survival rate of grafting potatoes and peppers. Background technique

[0002] Pepper is a warm-loving plant, and it has high requirements for temperature adaptation. The temperature range of pepper growth cycle is 12-35°C, and peppers below 12°C or above 35°C do not grow well. Most of the pepper seedlings currently planted are raised in the open air or in facility seedbeds. When the temperature is low during the seedling cultivation period, the pollen development is abnormal, which affects the normal pollination and fertilization in the later stage, resulting in flower drop and fruit drop, resulting in a significant reduction in pepper yield; secondly, moisture also affects the growth of pepper Another important indicator of water deficiency, too much water and lack of oxygen in the soil will cause the vitality of the root system to decline o...

Embodiment 1

[0089] In step 1, potatoes are selected as the rootstock, peppers are used as the scion, and the scion grows seedlings 30 days earlier than the rootstock.

[0090] Step 2, when the potato rootstock seedlings are 25cm high, take 150 potato rootstock seedlings and divide them into three groups on average. The first group removes all shoots and leaves, the second group removes all shoots and leaves only half leaves, and the third group removes all shoots and leaves. All the buds leave a leaf;

[0091] Step 3, when the pepper scion seedling grows to 20-25cm, obliquely cut the 45 ° angle from the seedling stem base, get 150 pepper scion,

[0092] Step 4, the hot pepper scion is treated with the activation formula for 30mim, and then it can be grafted with the above three groups of potato rootstocks,

[0093] Step 5: Cut the potato rootstock 10 cm across, cut vertically from the middle of its top, then insert the activated pepper scion into the stem incision of the potato, and fix ...
