Problems solved by technology

[0003] The purpose of the present invention is to provide a method for quantitatively predicting the maturity of flue-cured tobacco in the field for determining the suitable harvesting period of tobacco leaves. The method can accurately grasp the number of mature tobacco leaves in the field, and ensure that each batch of tobacco leaves can be harvested in a timely and appropriate amount. So as to effectively solve the problem that the mature harvest of flue-cured tobacco is difficult to implement for a long time, and then make the baking of flue-cured tobacco more professional and lean

Embodiment 1

[0051] Taking the barn group as the unit, all the tobacco fields in the curing area covered by the barn group were divided into four types of tobacco fields: "big strong tobacco", "medium strong tobacco", "weak tobacco" and "excessive tobacco" Category, count and fill in the area of ​​each tobacco field category, the area of ​​the above four categories of tobacco fields is 15 mu, and the planting amount per mu is 1100 plants; divide 2 representative monitoring fields in each tobacco field category Each representative monitoring field has an area of ​​1 mu and is marked on each representative monitoring field; one representative sampling point is selected in each representative monitoring field, and each representative sampling point 10 tobacco plants were selected as investigation tobacco plants, and these 10 survey tobacco plants were 10 continuous tobacco plants growing in the same planting row, and the tops of the first and tenth tobacco plants were marked.

Embodiment 2

[0061]Divide the tobacco fields into three types of tobacco fields: "big strong tobacco", "medium strong tobacco" and "excessive tobacco", count and fill in the area of ​​each type of tobacco field, the area of ​​the above three types of tobacco fields is 20 mu, the planting amount per unit area is 1,000 plants; each category of tobacco field is divided into 1 representative monitoring field, and the area of ​​each representative monitoring field is 1 mu and marked on the representative monitoring field ; Select 2 representative sampling points in each representative monitoring field, and select 8 tobacco plants in each representative sampling point as investigation tobacco plants, and these 8 investigation tobacco plants are continuous plants grown in the same planting row. 8 tobacco plants, mark the tops of the first and eighth tobacco plants.

Embodiment 3

[0070] Divide the tobacco fields into two categories of "big strong tobacco" and "medium strong tobacco", count and fill in the area of ​​each type of tobacco field. The area of ​​the above two types of tobacco fields is 13 mu, and the planting amount per mu Both are 1200 plants; divide 2 representative monitoring fields in each tobacco field category and mark each representative monitoring field, determine and fill in the area of ​​each representative monitoring field (each representative The area of ​​the permanent monitoring field is 1 mu); select 2 representative sampling points in each representative monitoring field, and select 12 tobacco plants in each representative sampling point as the survey tobacco plants, and the 12 survey tobacco plants The tobacco plants are 12 consecutive plants grown in the same planting row, and the tops of the first and twelfth plants are marked.

[0071] From the first round of tobacco leaf curing (May 5th), field surveys of tobacco leaf ma...

Abstract

The invention relates to the technical field of agricultural production and in particular relates to a flue-cured tobacco maturity field investigation and quantitative forecast method for determiningsuitable harvesting period of tobacco. The method comprises the following steps: dividing a tobacco field into at least one type; dividing at least one representative monitoring field piece in each ofthe types of the tobacco field; selecting at least one representative sampling point in each representative monitoring field piece; selecting 8-12 tobacco plants as investigation plants at each representative sampling point, and performing tobacco maturity investigation, wherein the maturity investigation comprises counting mature leaves of each investigated tobacco plant and counting suitable harvesting tobacco amount of all tobacco plants in each type of the tobacco field in each baking round when green color of the tobacco starts to fade in the first round and before the tobacco is mature;and comparing the suitable harvesting tobacco amount with single one-baking suitable tobacco filling amount. According to the method, the quantity of mature tobacco leaves in the field can be accurately mastered, each batch of the mature tobacco leaves can be appropriately harvested at the right time, and the problem that mature tobacco harvesting is difficultly realized is solved immediately. Therefore, the tobacco production is specialized and accurate.

Description

technical field [0001] The invention relates to the technical field of agricultural production, and in particular to a method for quantitatively predicting the maturity of flue-cured tobacco in field surveys for determining the appropriate harvesting period of tobacco leaves. Background technique [0002] In the tobacco industry, the maturity of tobacco is of great significance to the production and quality of tobacco leaves. Today’s flue-cured tobacco production field rarely has a practical method for precise and quantitative calculation of harvestable tobacco leaves. When tobacco farmers determine the harvesting period of tobacco leaves in the field, they often make decisions based on their feelings and extensive experience, which often leads to overripe harvesting, underripe harvesting or Unripe harvesting has seriously affected the quality potential of fresh tobacco on the one hand, and on the other hand has seriously affected the curing characteristics of tobacco leaves...
