AI Technical Summary

Problems solved by technology

There are problems and deficiencies in the current method of egg detection and reporting: 1. The amount of eggs lured is low, which affects the accuracy of forecasting; 2. The material is mainly straw, which is easy to mold and rot in rainy weather, which is not conducive to trapping; 3. Straw handles every 3 days It needs to be changed once, and it must be tied into small handles. It is time-consuming and labor-intensive with the help of small wooden sticks or thin bamboo poles; , it takes 8-10 minutes for each grass to be checked by each person, and it takes about 1.5 hours for 10 whiskers

Embodiment 1

[0025] 1) Prepare Di grass: Harvest Di grass in mid-February 2013, cut off Di grass from the second node on the ground, select 15 plants with 10-15 leaves, and dry them naturally for 14 days;

[0026] 2) Attracting armyworm eggs: On March 9, when the number of moths continuously increasing, select a representative wheat field with an area of ​​0.4hm 2 , insert the Dicao prepared in step 1) in a checkerboard pattern between the wheat rows of the selected representative wheat field. The top of the Dicao is higher than the wheat plants. There are 10 plants in each field, and the Dicao is replaced every 10 days;

[0027] 3) Detect the amount of fallen eggs: count the amount of fallen eggs every 3 days, peel off the leaves to check the fallen eggs, count the number of fallen eggs (including the dead leaves of the leaves), and count the 10 grasses inserted in step 2) in a representative wheat field The number of eggs dropped, and the time required to count the number of eggs dropped...

Embodiment 2

[0029] At the same time as in Example 1, select an area of ​​0.4hm next to the selected representative wheat field in Example 1 2 The wheat field is another representative wheat field. According to the existing technology, straws are used to lure the eggs of the armyworm. The grass handles are inspected and replaced every 3 days. The number of eggs dropped by straw handles is measured, and the time required for counting the number of eggs dropped by 10 straw handles is 68 minutes.

Embodiment 3

[0032] 1) Preparation of Dicao: Harvest Dicao in mid-February 2014, cut Dicao from the second node on the ground, select 15 plants with 10-15 leaves, and dry them naturally for 17 days;

[0033] 2) Attracting armyworm eggs: On March 11, when the number of moths continuously increasing, select two representative wheat fields with an area of ​​0.3hm 2 , Insert the Digrass prepared in step 1) in a checkerboard pattern between the wheat rows of the selected representative wheat field, the top of the Digrass is higher than the wheat plants, 10 plants per field, and replace the Digrass once every 15 days;

[0034] 3) Detect the amount of fallen eggs: count the amount of fallen eggs every 3 days, peel off the leaves to check the fallen eggs, count the number of fallen eggs (including the dead leaves of the leaves), and count the 10 grasses inserted in step 2) in a representative wheat field The number of eggs dropped, and the average time required to count the number of eggs dropped ...

Abstract

The invention discloses a method for forecasting armyworm eggs by using triarrhena sacchariflora to lure the armyworm eggs. The method comprises the following steps that (1) the triarrhena sacchariflora is prepared, specifically, the triarrhena sacchariflora is harvested in the middle ten days of February every year and cut off at the second section on the ground, and triarrhena sacchariflora plants with 10-15 leaves are selected and naturally dried in the sun for 14-17 days; (2) the armyworm eggs are lured, specifically, when the moth luring number is increased continuously, one or two representative wheat fields are selected, the area of each wheat field is not less than 0.3 hm<2>, the triarrhena sacchariflora plants prepared in the step (1) are inserted between rows of the representative wheat fields in a chess board form, triarrhena sacchariflora tops are higher than wheat plants, every ten triarrhena sacchariflora plants are planted in each field, and the triarrhena sacchariflora plants are replaced every 10-15 days; and (3) the accumulated egg number is detected, specifically, the accumulated egg number is added up once every three days, accumulated eggs are counted by unfolding leaves, the accumulated egg number, including the number of eggs in withered and curled parts of the leaves, is added up, and the number of accumulated eggs on the ten triarrhena sacchariflora plants inserted in each representative wheat field is added up. According to the method, the luring number of the armyworm eggs is large, the forecasting accuracy rate is high, labor and time are saved, and the forecasting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for detecting and reporting the armyworm eggs by using Digrass to lure the armyworm eggs. Background technique [0002] Armyworm is an important pest of gramineous plants. Only by adopting good investigation methods can accurate forecasting and good control be guided. Egg trapping is one of the important methods. At present, the technology mainly used for trapping eggs of armyworms is the method of trapping eggs with grass handles in item 1 of Article 3 of the "Specifications for the Survey and Report of Armyworms of the Ministry of Agriculture of the People's Republic of China GB / T 15798-1995". It is also a common technique used by current plant protection personnel; when the amount of moth lures continues to increase, select 1 to 2 representative wheat fields (the area of ​​each field is not less than 0.3hm2) 2 ), insert 10 small grain grass handles in a checkerbo...
