Chinese walnut
kernel
A walnut is the nut of any tree of the genus Juglans. Technically a walnut is the
seed of a drupe or drupaceous nut, and thus
not a true botanical nut. It is used for food after being processed while
green for pickled walnuts or after full ripening for its nutmeat. Nutmeat of
the eastern black walnut from the Juglans
nigra is less commercially available, as are butternut
nutmeats from Juglans
cinerea.
The walnut is nutrient-dense with protein and essential fatty acids.Our Chinese walnut is grown
in Xinjiang province of China. The
output of it increases 33.33% this year.

There are about 60 kinds of vegetables cultivated in Guichi District. With the changes in the economic structure of the countryside, manual weeding is done by relying on a small amount of leftover labor force, and we can no longer control the damage caused by weeds. Therefore, the quick and effective chemical weeding method is effective. Began to test the application on vegetables. First, the cultivation of vegetables in our district 1, a wide range of vegetables. There are about 60 kinds of vegetables grown in our district. The main vegetables are divided into root vegetables (radish, carrots, etc.); yams (potato, ginger, wolfberry, etc.); onions and garlic (onions, garlic, etc.); cabbage (Chinese cabbage, cabbage, etc.); mustard (leaf Mustard, stem mustard, etc.); cabbage (cabbage, cabbage, etc.); leafy vegetables (spinach, lettuce, celery, etc.); melons (cucumber, wax gourd, pumpkin, etc.); Solanum (tomato , eggplants, green peppers, peppers, etc.); beans (faba beans, kidney beans, peas, lentils, etc.); perennial vegetables (day lily, asparagus, bamboo shoots, citrons, etc.); aquatic vegetables (potato, peony, sagittaria, etc.). 2, the cultivation method is complicated. The current main cultivation methods are: (1) Open cultivation. Including live vegetables (such as cabbage, radish, etc.) and transplanting vegetables (tomatoes, eggplants, green peppers, etc.), and (2) mulching cultivation. In the early spring, after direct seeding or transplanting in open field, cover film cultivation includes potato, pepper and tomato; (3) cultivation in protected areas. Including greenhouse vegetable cultivation and greenhouse vegetable cultivation, mainly cucumber, tomato and other high-yield species and breeding seed production. 3, intercropping, interplanting general, water and fertilizer management fine. Vegetable intercropping and interplanting are not only common, but also varied in form. For example, long-growing varieties and fast-growing vegetables with short growth periods are intercropped and interplanted; intercropping or interplanting of high- and low-vegetable vegetables, and intercropping of vegetable grains and vegetables. The cultivation and management of vegetables is fine and the water and fertilizer are sufficient. II. Types and distribution of weeds in vegetable fields The main types of weeds in vegetable fields include grasses, green dog tails, marmots, crabgrass, amaranthus, aphrodisiac, bluegrass, headgrass, bermudagrass, and cattle breeds.缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕 缕. Our district is located in the subtropical zone. Since the rainfall is concentrated between spring and summer, combined with high temperatures, weeds are concentrated in the spring and summer. Third, the characteristics of chemical weeding in vegetable fields In the past, control of weeds in vegetable fields mainly depended on labor. In the past 10 years, effective and efficient chemical weeding methods have begun to be applied in vegetable growing areas. Due to the variety of vegetables and the varying degree of resistance of various vegetables, chemical weeding in vegetable fields is more complicated. Due to the complex cultivation methods, not only the occurrence time and growth rate of weeds are significantly different under different conditions of temperature and humidity, but also herbicides. The effect of drug efficacy and the formation of phytotoxicity are also different. For example, greenhouses have high temperatures, high humidity, early emergence of weeds, and high herbicide efficacy. Therefore, at the same dose, the open field application does not produce phytotoxicity, while greenhouse or greenhouse applications are prone to injury; due to frequent crop rotations, weed herbicides must be considered in addition to the weed control efficacy. Safety; due to intercropping and interplanting, when selecting herbicides, in addition to considering the safety of the main objects of protection and the effect of weed control, we must also consider the safety of herbicides for intercropping or interplanting crops; due to the abundant water and fertilizer in vegetable fields, weed species There are many kinds of weeds that are close to or closely related to the vegetables, which limits the selection and application of herbicides. Since most vegetables have a short growing period and they are eaten soon after harvest, residues, residues, and other problems also limit weeding. The selection and application range of the agent; coupled with the slow start of chemical weed control in vegetable fields in China, it is currently limited to a few species, and there are few specialized herbicides to control weeds in vegetable fields. Therefore, these herbicides are not sufficiently targeted. Affects control effectiveness and selectivity. In view of the above characteristics, chemical field weeding in vegetable fields is more difficult, especially based on the types of vegetables, the object of control, the ecological environment, and the period of prevention and treatment. Due to species, origin, and time, careful selection of suitable and safe herbicide species, dosage, and time And application methods to ensure the protection of the ecological environment and reduce production costs while preventing weeding and increase revenue. Fourth, vegetable field chemical weeding strategy 1, transplanting vegetables. Transplanting vegetables is transplanted to Daejeon after the nursery stage, so the tolerance to herbicides is stronger. Before transplanting, soil treatment or transplanting before the first to control the emergence of weeds, the following herbicides can be selected as appropriate: 50% acetochlor EC, 60% butachlor EC, 10% glyphosate and other agents. 2, all kinds of broadleaf vegetables. The stem and leaf treatment agents such as barnyardgrass and gaisengeng are very safe for broad-leaved plants, and they have excellent control effects against monocotyledonous weeds and can be widely applied to control broad-leafed vegetables to control various monocotyledonous weeds. 3, small seeds seeded live or seedbed. Such vegetables are more sensitive to herbicides, and many herbicides that can be used to transplant vegetables may affect the emergence of such vegetables and even die gradually after emergence. Herbicides contain 50% acetochlor and other oils. 4, aquatic vegetables. The herbicides that can be used to control such vegetable field weeds include 50% paracetamol WP and 60% butachlor WP. 5, cultivate vegetables in protected areas. (1) Cultivation of plastic film. Herbicides that can be selected before transplanting include 50% acetochlor EC, 60% butachlor EC, and 12.5% ​​oxacin EC. (2) Cultivation in greenhouses. Due to the high temperature and humidity in the greenhouse, the airtightness in the shed is closed, and most of the herbicides are often used in greenhouses. Therefore, to carry out chemical weeding, it is necessary to comprehensively consider various factors such as the type of vegetables, varieties, cultivation time, cultivation methods, soil quality, and management methods, and to use herbicides rationally. At present, a broad range of herbicides are used in vegetable field soil treatment such as acetochlor, ditertilamine, and cable. Such herbicides have good effects on annual grass weeds; diuron and other herbicides and weeds Leaf weeds are effective, killing grass broad spectrum.
