[0003] Due to the increasing demand for fresh and dried water chestnuts in recent years, wild water chestnut resources can no longer meet the demand, and excessive human exploitation has caused serious damage to wild water chestnut resources. In order to meet the growing demand and protect wild water chestnut resources and increase farmers' income, the artificial breeding and planting technology of water chestnuts has received increasing attention; however, in the production process of water chestnuts, the survival rate of water chestnut cuttings is not high. At the same time, the fruits of water chestnuts are easily damaged by pests such as bat moths and fruit moths, resulting in low yields and low economic benefits. Therefore, in response to the above problems, we have developed a water chestnut planting method, which can effectively solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a method for planting water angelica, which can effectively solve the problems that the survival rate of water angelica cuttings is low in the water angelica production process, and the fruits of the water angelica are easily damaged by pests such as bat moths and fruit-sucking armyworms, resulting in low yield and low economic benefits.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] Provided is a method for planting water hyacinth, comprising the following steps, characterized in that: a. site selection and land preparation: selecting a fir forest with a slope of less than 45 degrees and a tree age of more than 8 years; cleaning up the dead branches and weak branches on the trunks, and at the same time cleaning up the weeds and gravel on the ground, and then leveling the ground; and b. planting: from April to June each year, planting at a density of 150 cm to 200 cm × 150 cm to 200 cm, and applying phosphate fertilizer at an amount of 10 kg to 20 kg per mu; after planting, starting from the second year, inter-row cultivation, weeding and loosening the soil once in spring, summer and season each year, and at the same time Apply organic fertilizer once, the amount of organic fertilizer is 10kg ~ 15kg per mu; c, care: on the basis of step b, when the water hyacinth seedlings grow to 100 cm high, start to remove weak branches and tidy up the tree shape; d, disease and pest control: the disease and pest control is divided into: ripe rot control, leafhopper control, fruit sucking moth control, bat moth control; e, fruit harvesting and processing: harvesting, summer fruit is generally 75 days after flowering, winter fruit is 110 days after flowering, and the fruit skin color has shown a waxy yellow color. Processing, because the fruit contains a lot of juice and its flesh is also The fruit is thin, the hardness of the fruit ridge is poor, and the transportation is weak. Therefore, the harvested fruits need to be dried and stored in time. Pick the bad fruits first, then wash them, put them in the dryer for drying, and then seal them for storage; f. Seedling cultivation: In the winter of the first year, select strong and disease-free branches that have been lignified, cut them into 5 cm long sections, soak them in disinfectant for 30 minutes, then take them out to dry the water, and then store them in a foam box; in March of the second year, wait for callus tissue to grow at both ends of the branches, and then put them in the seedling box for cuttings for the first seedling cultivation. During this stage, spray every 10 days. Water once; after 1-3 months, the branches begin to take root and sprout. At this time, take out the water hyacinth seedlings from the seedling box together with the culture medium, and then transplant them to the ground in a cool place for the second seedling cultivation. During this stage, spray water every 3 days; the second seedling cultivation requires digging holes in the ground, and the size of the holes refers to the size of the culture medium; the second seedling cultivation spacing is 30 cm × 30 cm; when the water hyacinth seedlings of the second seedling cultivation grow to 30 cm in height, remove the top buds to promote the development of their root system; from April to June of the third year, the water hyacinth seedlings of the second seedling cultivation can be transplanted under a fir forest.

[0007] The ripe rot control described in step d is caused by infection of the pathogenic bacteria of Botrytis cinerea, and the symptoms are: when the fruit of the water hyacinth is close to maturity, an indentation spot appears on the fruit, which is slightly sunken and brown, and the slightly yellowish flesh is revealed after peeling off the cortex, the edge of the lesion is dark green or water-stained, and there is often a milky white cone-shaped rot in the middle, which can expand to the middle of the flesh or even the whole fruit rot within a few days, and is an important disease during the storage period; the control steps are: first, the orchard is cleaned and pruned in winter, dead branches and fallen leaves are removed, and the parasitic sites of pathogens are reduced; secondly, young fruits are bagged within 1 week after the flowers have faded to avoid infection of the young fruits; and from 2 weeks after the flowers have faded to May to August during the fruit expansion period, 50% carbendazim 800 times solution, 1:0.5:200 Bordeaux mixture or 80% thiophanate wettable powder 1000 times solution can be sprayed on the tree crown 2 to 3 times, with an interval of 20 days between each spraying.

[0008] The leafhopper control described in step d is that the leafhopper has four generations a year, and the fourth generation adults overwinter in winter green manure crops and weeds. The first generation adults lay eggs in mid-to-late April, and the eggs are laid in the mesophyll on the back of the leaf near the main vein, in strips along the main vein. The second generation adults occur from mid-June to mid-July, which is the peak period of the year. The symptoms are: yellow-white spots appear on the affected leaves at the beginning, gradually expanding into pieces, and in severe cases, the whole leaves turn pale and fall early, the tree body becomes weak, and the yield drops sharply. The control steps are: strengthen ventilation and light transmission, remove weeds in and around the orchard, and timely plow and backfill the green manure in winter; spray with 40% omethoate 1:1200 times solution, 10% multi-acid 1:2500 times solution, and 25% or 50% pirimicarb wettable powder 4000 times solution.

[0009] The control of the fruit-sucking moth described in step d, the fruit-sucking moth has 3 to 4 generations in one year, and both larvae and adults can overwinter, forming three peak periods of occurrence in mid-to-late June, mid-to-late August, and mid-September to mid-October, and the third generation of adults are mostly the ones that damage the fruits of the water hyacinth. Its symptoms are: when the fruit is nearly ripe, the adult mouthparts pierce the water hyacinth peel and suck the juice. After one week, the peel at the puncture hole turns yellow and sags and glue flows out. Thereafter, the area near the wound becomes soft and rotten, and gradually expands into an oval water-soaked patch, and finally the whole fruit rots. Control steps: do a good job of garden cleaning, bag the fruits, use an aqueous solution of 8% sugar and 1% vinegar plus 0.2% sodium fluoride to lure the fruit-sucking moth to suck, and then catch it manually.
