Problems solved by technology

But the root system growth of Western squash is not as vigorous as that of Chinese pumpkin, and it is generally not resistant to high temperature and has poor resistance. It is easy to be infected with viruses in hot summer. Late sowing in spring or autumn cultivation often results in failure of harvest due to disease, which has great limitations in application. sex

Embodiment 1

[0026] The method for grafting and strong seedlings of pumpkin and Chinese pumpkin of the present embodiment comprises the following steps:

[0027] 1. Rootstock selection

[0028] The locally cultivated heat-resistant and disease-resistant Chinese pumpkin "Big Pumpkin" was selected as the rootstock, and the high-quality Western pumpkin "Dongsheng" was selected as the scion.

[0029] 2. Prepare the seedbed

[0030] Choose a plot with high dryness and convenient transportation to build a greenhouse, and make a low north-south row in the greenhouse, with a depth of 30cm and a width of 1.2-1.5m. The length is determined according to needs. Lay electric heating wires on the seedbed of the nursery greenhouse, spread 5-8cm of nutrient soil evenly on the electric heating wire, step on it firmly, and then discharge the seedling bags filled with nutrient soil on the seedbed.

[0031] 3. Germination and sowing

[0032] On March 5th, the seeds of "big pumpkin" as rootstock will be soa...

Embodiment 2

[0051] The difference between this example and Example 1 is that the "big pumpkin" pumpkin is selected as the rootstock, and the "Dongsheng" pumpkin is used as the scion. The seeds of "big pumpkin" were soaked to accelerate germination, and sowed in seedling bags, one grain per bag. After the "big pumpkin" pumpkin seeds emerged, the seeds of western pumpkin "Dongsheng" were soaked and accelerated, and sown in Seedbeds or seedling trays. When the pumpkin seedlings of "Big Pumpkin" have grown to two leaves and one center, and the cotyledon leaves of "Dongsheng" seedlings have just unfolded, use the oblique cutting method to start grafting. After grafting, keep it closed and moisturized in the greenhouse for 4-6 days, maintain the relative humidity in the greenhouse above 95%, harden the seedlings at a temperature of 25-30°C during the day, and 15-20°C at night, then gradually ventilate, see the light properly, and maintain an average daily temperature of 20-20°C. 25°C, after tw...

Embodiment 3

[0056] The difference between this example and Example 1 is that the "long-legged" pumpkin is selected as the rootstock, and the "Dongsheng" pumpkin is used as the scion, and the seed soaking conditions of the "long-legged" pumpkin seeds are soaking in warm water at 55°C for 15 to 20 minutes , and take it out and let it cool naturally, soak the seeds with clear water for 3 to 4 hours at room temperature, then take out the pumpkin seeds and clean them, wrap the pumpkin seeds with gauze, and germinate them at a temperature of about 28°C. The field diseases of the grafted seedlings and the yield of mature melons are shown in Table 3.

[0057] table 3

[0058]

[0059] It can be seen from the above table that the grafted seedlings have heat resistance, disease resistance and stress resistance, and the yield is high, which is 85.3% higher than that of ordinary pumpkin seedlings.

Abstract

The invention relates to a Cucurbita maxima and Cucurbitamoschata grafting and strong seedling cultivation method which comprises the following steps of proper stock selection, germination accelerating, seeding, grafting, management after grafting and planting. By means of the Cucurbita maxima and Cucurbitamoschata grafting and strong seedling cultivation method, the grafting survival rate is improved; by utilizing the Cucurbitamoschata with strong disease resistance and stress resistance to serve as the stock, heat resistance, disease resistance and stress resistance of the Cucurbita maxima are improved, and quality advantages of the Cucurbita maxima are reserved; the purpose of high and stable yield of the Cucurbita maxima is achieved.

Description

technical field [0001] The invention relates to a method for grafting melons, in particular to a method for grafting Western pumpkins and Chinese pumpkins and cultivating strong seedlings, belonging to the technical field of plant cultivation. Background technique [0002] There are three main cultivars of vegetable pumpkins, namely, Chinese pumpkin (cucurbita moschata D), commonly known as pumpkin or rice melon; Indian pumpkin (cucurbita maxima D), commonly known as winter squash; American pumpkin (cucurbita pepo L), namely zucchini. In recent years, the pumpkins (also known as chestnut-flavored pumpkins) introduced from Japan, Taiwan and other places belong to Indian pumpkins botanically. Because of their rich nutrition, high quality, powdery, waxy, sweet taste, beautiful appearance, small and exquisite pumpkins, Very popular with consumers, making its cultivation area continue to expand. But the root system growth of Western squash is not as vigorous as that of Chinese p...
