Seedling culturing method for prompting earliness and high yield of cucurbita maxima

Abstract

The invention relates to a seedling culturing method for prompting the earliness and the high yield of cucurbita maxima. The seedling culturing method for prompting the earliness and the high yield of cucurbita maxima comprises the following steps that firstly, a seed bed is established; secondly, seedling culturing bags are filled with nutrient soil; thirdly, cucurbita maxima seeds are soaked with warm water with the temperature of 55 DEG C; fourthly, the small end of each cucurbita maxima seed is cut with scissors so that a small opening can be formed, the seeds are well wrapped with gauze, and accelerating germination is conducted; fifthly, after the cucurbita maxima seeds germinate, at noon on a sunny day in spring, each seedling culturing bag is punctured so that a small hole can be formed, each germinated seed is placed in one small hole with a bud facing downwards, and the small holes are covered with the nutrient soil; sixthly, in the period of seedling stage management, the conditions that the soil temperature of a seedling culturing bed in a seedling culturing greenhouse ranges from 20 DEG C to 28 DEG C in the daytime and the soil temperature of the seedling culturing bed in the seedling culturing greenhouse ranges from 15 DEG C to 20 DEG C at night are met, a potassium dihydrogen phosphate solution with the mass concentration being 0.3% is sprayed to cucurbita maxima seedlings one week before planting, and low-temperature seedling exercising is conducted; seventhly, planting is conducted, wherein strong seedlings are planted when it is cloudy, and the seedling culturing bags with the strong seedlings are transplanted to a field. The seedling culturing method for prompting the earliness and the high yield of cucurbita maxima can guarantee the uniformity of emergence of the seedlings and the survival rate of transplanting.

Description

technical field [0001] The invention relates to a seedling raising method for crops, in particular to a seedling raising method for promoting early maturity and high yield of pumpkin, 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. Because the root system of Western squash is not as vigorous as that of Chinese pumpkin,...

Problems solved by technology

However, when using traditional hole trays or nutrient pots for seedling cultivation, when the seedlings are removed and transplanted, the soil lumps on the roots of the seedlings are easy to loosen, causing the roots to be easily damaged, which in turn makes the seedlings difficult to survive or the slow seedling period is too long. Affected later growth and yield of zucchini

In addition, the seeds of zucchini have a hard shell, which leads to inconsistent seed germination after seed soaking and germination treatment
