Problems solved by technology

[0002] As a kind of temperature-loving vegetable, zucchini grows seedlings in deep winter. Due to the influence of low temperature and weak light, it will lead to low seedling emergence rate, excessive growth, root retting, damping-off and other diseases, resulting in low seedling rate and poor quality of seedlings, which directly affect Seedling effect

Embodiment

[0016] 1. Substrate formula: Among the 7 composite matrix formulas prepared with peat, perlite, and vermiculite as the main materials, bean dregs, and eggshells as auxiliary materials, formula M1 (peat: perlite = 3: 2), formula M6 ( Peat: perlite: vermiculite = 6: 3: 1 + a small amount of eggshell), formula M7 (peat: perlite: vermiculite = 6: 3: 1) has excellent physical and chemical properties. Height, stem height, stem diameter and cotyledon area have a good promotion effect, and the effect of formula M1 (peat:perlite=3:2) is the most significant. Therefore, the proportion of vermiculite should not be higher than 1 / 10. The more vermiculite content, the greater the humidity. Low temperature and high humidity will affect the emergence and quality of seedlings, and will also cause diseases.

[0017] 2. Germination time: The different germination times of zucchini seeds are 96 hours (the sprout length exceeds the seed length), 72 hours (the sprout length is more than 1 / 2 of the ...

Abstract

The invention discloses a cucurbita pepo seedling culture method used in late winter. The method includes following steps: well stirring and mixing turf and perlite according to a mass ratio of 3:2, adding certain amounts of organic fertilizer and chemical fertilizer, a mixing well to obtain a compound matrix; putting the obtained compound matrix into a hole tray with 18 holes, and selecting full cucurbita pepo seeds to complete germination accelerating of the same the day before seeding; seeding after germination accelerating is completed, and covering the hole tray with a layer of vermiculite. Detailed studies are made on the aspects like seedling culture matrix formulation, germination accelerating time during seeding (germination accelerating length), type of a covering material and specification of the hole tray, and seedling emergence rate, qualified seedling percentage and seedling quality are used as measure indicators to form a mature key technology for cucurbita pepo seedling culture in low-temperature seasons, so that the seedling emergence rate and the seedling quality are ensured, and the qualified seedling percentage reaches higher than 95%.

Description

technical field [0001] The invention relates to the field of plant seedling cultivation, in particular to a zucchini seedling cultivation method in deep winter. Background technique [0002] As a kind of temperature-loving vegetable, zucchini grows seedlings in deep winter. Due to the influence of low temperature and weak light, it will lead to low seedling emergence rate, excessive growth, root retting, damping-off and other diseases, resulting in low seedling rate and poor quality of seedlings, which directly affect Seedling effect. Contents of the invention [0003] In order to solve the above problems, the invention provides a method for raising seedlings of zucchini in deep winter, and has carried out detailed research from aspects such as seedling raising matrix formula, germination time (germination length) during sowing, covering material types and plug specifications, and the emergence rate , Seedling rate and seedling quality are the measurement indicators, form...
