Background
The weeding work of mulberry seedling raising and mulberry field management is directly related to success or failure of mulberry seedling raising and mulberry field management. The traditional artificial weeding has low efficiency and high cost, the mulberry seedlings can be damaged in the artificial weeding process of the mulberry seedling nursery, and 3-5% of the mulberry seedlings are pulled out along with the grass; under the conditions of high labor cost and general lack of labor force at present, the requirements of mulberry seedling raising and mulberry field management are no longer met by artificial weeding. In the chemical weeding aspect, two categories of biocidal herbicides and selective herbicides exist. The biocidal herbicide has killing effect on all plants, and can not be sprayed on crops when in use, so that the application range is limited. A single kind of selective herbicide can be sprayed on crops, but the weeding is not thorough and the weeding effect is poor. The selective herbicide is divided into two categories of a conifer herbicide and a broad-leaved weed herbicide, the conifer herbicide is safe for broad-leaved crops and cannot kill the broad-leaved weeds; broadleaf herbicides are safe for coniferous crops and cannot kill coniferous weeds. When one type of weeds is killed while another type of weeds normally grows, the growth of the undecided weeds is accelerated, and therefore, the selective herbicide of a single type has a problem of poor herbicidal effect. The mulberry belongs to broad-leaved plants, the coniferous herbicides are safe to the mulberry, the broad-leaved herbicides have different damage effects on the mulberry to different degrees according to different concentrations and different types, if the coniferous herbicides are only used, broad-leaved weeds cannot be removed, and when the coniferous weeds are killed, the remaining broad-leaved weeds can accelerate growth and have poor weeding effect. The compound herbicide which has high selectivity, can kill coniferous weeds and broadleaf weeds, has little damage to mulberry seedlings (mulberry) and does not influence the normal growth of the mulberry seedlings (mulberry) and has high efficiency and high selectivity is urgently needed in the aspects of mulberry seedling raising and mulberry field management.

The coniferous grass plants start to wither after 4 days, die after 6 days, die completely after 8 days, and the broadleaf grass plants start to wither after 2 days, die after 4 days and die completely after 6 days. The concentration and the proportion have good killing effect on both coniferous weeds and broadleaf weeds, but still have great harm to mulberry seedlings.
Example 4
The product is a herbicide screening experiment with 4 mature true leaves of mulberry seedlings as a test object and weeds with the height of 10-15cm as the test object.
(1) 50 liters of water were taken out.
(2) 350 ml of broadleaf herbicide, 200 ml of 13% aqueous methoxone sodium and 150 ml of 48% bentazon are added, and the mixture is fully mixed with water to dissolve the herbicide.
(3) 100 ml of 10.8% haloxyfop-R-methyl is added and dissolved by stirring and mixing with water.
(4) The mixed liquid was sprayed on mulberry seedlings (mulberry trees), and as a result: the shoots of the mulberry seedlings are withered on day 2, but recover on day 4 and all grow normally on day 5. The coniferous weeds have a wilting state on day 4 and all die on day 7. Broadleaf plants appeared severely wilted on day 2, started dying on day 4 and died all on day 6. The mulberry seedling is slightly damaged by the concentration and the proportion, the withered state is only 2-3 days, and the normal growth can be quickly recovered. Has good killing effect on both coniferous weeds and broadleaf weeds.
The solution of example 4 is optimal.
The implementation of the remarks:
(1) and (3) grasping an optimal spraying period: the height of weeds is 10-15cm, and the optimal spraying period is when 80% of mulberry seedlings have 4 mature true leaves. The dosage is the least, the effect is the best, the cost is the lowest, the height of the weeds cannot exceed 15cm, otherwise, the weeding effect is influenced.
(2) In order to ensure the weeding effect, the medicine is required to be prepared and used at present.
(3) The leaf surface can be sprayed only after dew is dried, and rain can not be generated within 8 hours after spraying.
(4) When the weed leaf surface spraying agent is used for spraying, the fog point must be adjusted to be the finest, and the weed leaf surface can be completely sprayed with moisture.
(5) The spraying can not be carried out when drought or waterlogging occurs or the mulberry seedlings grow abnormally.
(6) The fertilizer cannot be applied immediately after the pesticide is sprayed, and the fertilizer is applied in rainy days after the weeds die.
