Problems solved by technology

[0004] What does not match the increase in output and area is that the improvement of watermelon production efficiency is slow, and the profit margin is greatly affected by rising raw material and market price factors. The ability to resist risks is poor, resulting in low production efficiency, which is not in line with the high-quality development direction of the watermelon industry

Embodiment 1

[0052] The test material is the watermelon variety 'Beyond Dream'. After the seeds are soaked in warm water to accelerate germination, seedlings are raised in 50-hole plug trays. The seedling substrate is mixed with peat, perlite, and vermiculite at a ratio of 1:1:1. When the seedlings grow to three leaves and one heart, they are transplanted into a cultivation tank filled with coconut peat for cultivation. During the cultivation period, the Hoagland formula nutrient solution is used for water and fertilizer supply. Select the second or third female flower fruiting melon between 14-20 nodes, and treat it as a test material after the female flower is left to bloom.

[0053] GABA concentration screening

[0054] Nutrient application at flowering stage: Spray the ovary with 20-80mM GABA, and the spraying amount is 2mL. At the same time, the water control was set as Control. For each treatment of 20 plants, and 30 days after treatment, select 6 watermelon fruits with relatively ...

Embodiment 2

[0080] Test material is watermelon variety 'Beyond Dream', and other is with embodiment 1.

[0081] Screening for different application methods

[0082] Flowering nutrient application: with 40mM GABA+6mM CaCl 2 +0.5% ethoxy-modified polytrisiloxane was sprayed on the ovary, pH=6.0, and the spraying amount was 2 mL.

[0083] root drip irrigation

[0084] Root drip irrigation was carried out 6 days before harvesting, 10ml per plant. The ingredients are the same as above.

[0085] Leaf spray

[0086] Spray leaves 6 days before harvest, 10ml per plant. The ingredients are the same as above.

[0087] Pre-harvest nutrition and application: use different application methods 6 days before harvest, treat 20 plants per treatment, and select 6 watermelon fruits with relatively consistent growth and size 6 days after treatment, measure the quality indicators such as fruit soluble sugar, protein, etc., test Set 3 repetitions.

[0088] It can be seen from Table 6 that the effects of...

Abstract

The invention discloses a composition for improving watermelon fruit quality and application thereof, and belongs to the technical field of plant cultivation. The composition which has the pH value of 6.0 and contains gamma-aminobutyric acid, CaCl2 and ethyoxyl modified polytrisiloxane is applied to watermelon, so that the transverse diameter, the longitudinal diameter, the weight of a single fruit, the content of soluble solids, the content of soluble protein and the content of Vc can be obviously increased, and a foundation is laid for high-quality cultivation of watermelons in facilities.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a composition for improving the quality of watermelon fruit and an application thereof. Background technique [0002] In recent years, with the continuous improvement of people's income level, people have put forward higher requirements for a better life. In terms of demand for agricultural products, it is no longer the pursuit of full food, but good food and safe food. In particular, the demand for high-quality vegetable products with excellent taste and safety is constantly increasing. [0003] China is the country with the largest facility area in the world. In 2020, the area of ​​facility vegetables will reach more than 59 million mu, which has become an important guarantee for promoting farmers' income and social and economic growth. China is the largest producer of watermelon in the world. The cultivation area, total output and per capita consumption ...
