Problems solved by technology

In the production process of green food, the requirements for the use of fertilizers are relatively high. The fertilizers allowed to be used at this stage can guarantee the quality of green food after use, but these fertilizers often have the problems of low effective nutrients and low utilization rate.
[0003] In current production, due to reasons such as improper management of fertilizer and water, use of zucchini hormone treatment, or damage from pests and diseases, the decrease in sweetness and quality deterioration of watermelon fruits have become the main problems affecting the quality of watermelons.

Embodiment 1

[0010] Embodiment 1, a kind of quality improving agent that improves watermelon sugar content, quality improving agent is the stachyose aqueous solution that mass concentration is 0.05%, promptly contains the stachyose of 0.5g in every 1kg stachyose aqueous solution.

[0011] Put stachyose into water according to the above weight ratio, and simply stir to obtain the above quality improver.

[0012] Experiment 1. Taking 8424 watermelon varieties as the experimental object:

[0013] Experimental group: starting on the 5th day after watermelon pollination, use the above-mentioned quality improver (embodiment 1) to carry out uniform foliage spraying on the front and back two functional leaves of the watermelon sitting on the melon node until the watermelon fruit is fully ripe and harvested Finish the foliage spraying after the end, spray a quality improver every 5 days, and each consumption is 10mL.

[0014] Contrast group 1: replace the quality improver with water, and the rest ...

Embodiment 2

[0020] Embodiment 2. A quality improver for increasing the sugar content of watermelon. The quality improver is a stachyose aqueous solution with a mass concentration of 0.045%, that is, every 1 kg of stachyose aqueous solution contains 0.45 g of stachyose.

[0021] Experiment 2, taking the Xiaofang watermelon variety as the experimental object:

[0022] Experimental group: starting on the 5th day after watermelon pollination, use the above-mentioned quality improving agent (embodiment 2) to carry out uniform foliage spraying on the front and back two functional leaves of the watermelon sitting on the melon node until the watermelon fruit is fully ripe and harvested Finish the foliage spraying after the end, spray a quality improver every 5 days, and each consumption is 10mL.

[0023] Contrast group 1: replace the quality improver with water, and the rest are the same as the experimental group.

[0024] Contrast group 2: start on the 5th day after watermelon pollination, spra...

Abstract

The invention discloses a quality modifier for improving watermelon sugar and a using method thereof. The quality modifier is 0.045 to 0.055 mass percent aqueous solution of stachyose. The invention also discloses the using method for the quality modifier at the same time, which comprises the following steps of: from the fifth day after a watermelon is pollinated, spraying the quality modifier to front and rear two functional leaves at a fruiting node of the watermelon, finishing leaf spray till the watermelon fruit is totally matured and picked, and spraying the quality modifier every 5 days, wherein the using amount is 10 milliliters every time. The quality modifier can effectively improve the sugar content of the watermelon.

Description

technical field [0001] The invention belongs to the technical field of regulating watermelon quality and sugar content through cultivation technology, specifically relates to a novel preparation and a use method for increasing watermelon sugar content, and provides a method for regulating watermelon quality and sugar content in production. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for watermelon quality, and green food is more and more popular among people, occupying a huge market. In the production process of green food, the requirements for the use of fertilizers are relatively high. The fertilizers allowed to be used at this stage can guarantee the quality of green food after use, but these fertilizers often have the problems of low effective nutrients and low utilization rate. [0003] In current production, due to reasons such as improper management of fertilizer and water, use ...
