preparation example 1

[0051] Establish a database of weather coefficient a

[0052] This application has established a database of weather coefficient a, and the specific methods are as follows:

[0053] (1) Take the red bunched small tomato plant as an example, collect the yield data of tomato under different average daily light levels; set the daily average basic light level of the tomato plant to 1000J / cm 2 ;

[0054] (2) Taking the daily average light amount as the abscissa and the tomato yield as the ordinate, establish the relationship curve between the daily average light amount and the tomato yield, and define the slope of the curve as the weather coefficient a.

[0055] In this preparation example, in order to describe the changing trend of the weather coefficient a, some representative data are selected from the weather coefficient a database (the illumination coefficient is 1000J / cm, respectively). 2 , 1100J / cm 2 , 1300J / cm 2 , 1500J / cm 2 , 800J / cm 2 , 600J / cm 2 , 500J / cm 2 The t...

Embodiment 1-4

[0062] Embodiments 1-4 provide a method for estimating fruit yield, respectively. In the above-mentioned method for estimating fruit yield, the fruit is a small red bunch harvested tomato.

[0063] The difference of the above-mentioned embodiment is: the season (month) of tomato yield estimation, specifically as shown in Table 2.

[0064] (1) Calculation of color change rate V: First, a light detection device is established to detect the daily average cumulative amount of light radiation received before and after tomato color change, and the time required for tomato color change in different seasons (months) is obtained, and then the color change rate V is calculated. ; The formula for calculating the rate of color change V is: rate of color change V = the number of tomatoes on a single bunch of fruit ears Y / the number of days T for color change.

[0065] (2) According to the color change rate V, calculate the number N of tomatoes that can be ripened on a single bunch of frui...

Embodiment 5-6

[0075] Embodiment 5-6 provides a kind of fruit yield estimation method.

[0076] The difference between above-mentioned embodiment and embodiment 3 is: the estimated time of tomato yield; that is, the number of days P in the future, specifically as shown in Table 3.

[0077] The time that tomato yield is estimated in the fruit yield estimation method that table 3 embodiment 3, embodiment 5-6 provide

[0078]

[0079]

[0080] In the fruit yield estimation method that embodiment 5-6 provides, the concrete steps that step (3) counts the number of fruit ears M that can be ripened in a single bay are: when the number of days in the future P is 14 days or the number of days in the future P is the tomato of 21 days When estimating the yield, it is necessary to estimate the number of fruit ears M that can be ripened in a single bay with a future number of days P of 7 days or a future number of days of P of 14 days.

[0081] When the number of days P in the future is 7 days, th...

Abstract

The invention relates to the technical field of agriculture, and particularly discloses a fruit yield estimation method and application thereof. The fruit yield estimation method comprises the following steps: calculating a color change rate V, calculating the number N of matable fruits on a single cluster of clusters according to the color change rate V, counting the number M of matable clusters in a single open room, calculating the average weight W of a single fruit and the total number U of fruits on the single cluster of clusters, counting the open room number A of a single row and the number B of planted rows, and estimating the fruit yield. The invention further discloses application of the fruit yield estimation method in the aspect of fruit yield estimation. According to the fruit yield estimation method provided by the invention, the yield of the fruits can be simply, quickly and accurately estimated.

Description

technical field [0001] The present application relates to the technical field of agriculture, in particular to a fruit yield estimation method and application thereof. Background technique [0002] With the rapid development of agricultural technology, multi-span glass greenhouses, as a new type of plant cultivation facility, have won the unanimous favor of the planting industry. Because of the temperature control equipment inside the multi-span glass greenhouse, the plants can be kept within a specific temperature range, thus ensuring that the plants can grow normally throughout the year. Therefore, farmers use multi-span glass greenhouses to grow temperature-loving plants in low-temperature seasons that are not suitable for plant growth, so as to obtain off-season fruits and vegetables, so that people can eat fresh fruits and vegetables all year round. [0003] In recent years, the most planted plant in greenhouses is tomato, its planting range is getting wider and wider,...
