Embodiment 1

[0011] Embodiment 1, a kind of quality improving agent that improves watermelon sugar content, this quality improving agent is the NaCl aqueous solution that NaCl molar concentration is 150mM.

[0012] The above quality improver can be obtained by dissolving NaCl in water and simply stirring.

[0013] Experiment 1. Taking 8424 watermelon varieties as the experimental object:

[0014] 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.

[0015] Contrast group 1: replace the quality improver with water, and the rest are the same as the experimental group.

[0016] Contrast group 2: start on the 5th day after wate...

Embodiment 2

[0026] Embodiment 2, a kind of quality improving agent that improves watermelon sugar content, this quality improving agent is made of NaCl, KNO 3 and water, the molar concentration of NaCl in the solution is 150mM, KNO 3 The molarity in solution is 15 mM.

[0027] NaCl and KNO 3 Dissolve in water and simply stir to get the above quality improver.

[0028] Experiment 3, replace the quality improver described in Example 1 with the quality improver described in Example 2, add a contrast group 3, and the rest are the same as Experiment 1.

[0029] Contrast group 3: starting on the 5th day after watermelon pollination, using KNO with a molar concentration of 15mM 3 Spray the watermelon evenly on the two functional leaves before and after the melon node with the aqueous solution, until the watermelon fruit is fully ripe and harvested, the foliar spraying is completed, and the quality improver is sprayed every 5 days. 10mL.

Abstract

The invention discloses two quality improvers for improving sugar of a watermelon, wherein one quality improver is a NaC1 water solution with molar concentration of 140-160mM; and the other quality improver is a solution which consists of NaC1, KNO3 and water, the molar concentration of the NaC1 in the solution is 140-160mM, and the molar concentration of the KNO3 in the solution is 14-16mM. The invention further discloses an application method of the quality improvers. The method comprises the following steps: From the fifth day after a watermelon is pollinated, spraying the quality improvers on a front functional leaf and a rear functional leaf at a watermelon setting node until the watermelon is fully ripe, picking the watermelon, ending spraying leaves, and then spraying 10mL of the quality improver once every five days. By utilizing the quality improvers of the invention, the sugar content of the watermelon can be effectively improved.

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. For watermelon, its fruit quality depends to a large extent on the type and content of sugar in the frui...
