Abstract

At present, when planting vegetables, a great quantity of truck farmers unreasonably match the crops for rotation of vegetables and food crops, therefore, the crops for rotation are out of joint; simultaneously, when planting vegetables, truck farmers can not reasonably match organic fertilizer and inorganic fertilizer but use high residue pesticide and highly toxic pesticide, thereby not only directly harming the physical health of consumers but also severely damaging the ecological environment of vegetable field. With the advancement of the society and the improvement of living standard, people lay higher and higher requirement on diet quality, increasingly attach importance to the ecological environment and bring forward higher requirements on the production and the consumption of vegetable products. In order to meet the requirement of people on harm-less vegetables, the invention provides a harm-free cultivation technology for broccoli. Land without industrial waste water, waste gas and solid waste is selected as the vegetable land and applied with sufficient organic fertilizer, high-yield breeds of broccoli are selected, and inorganic fertilizer and pesticide are reasonably applied in the plantation and growth of broccoli, so as to ensure high yield and no harm of ripe broccoli.

Description

Harm-free cultivation technology for broccoli

Affiliated technical field

The present invention relates to a kind of culture technique of vegetables broccoli, be particularly useful for the land for growing field crops and produce.

Background technology

At present, during many vegetable grower's planting vegetables, because vegetables and the collocation of grain plant crops for rotation are unreasonable, crops for rotation disconnect, and delay farming season, again less than good economic benefit, influence the enthusiasm that the vegetable grower plants vegetables.Simultaneously, some vegetable growers can not reasonably combined fertilizer and inorganic fertilizer when planting vegetable, uses persistent pesticide and highly toxic pesticide, not only directly endangers the healthy of consumer, also heavy damage field of vegetables ecotope.Along with the progress and the growth in the living standard of society, people are more and more higher to the requirement of meals quality, and to the understanding of ecotope also pay attention to day by day, production and consumption is also had higher requirement to victual.Therefore original growing vegetables technology incompatibility people is necessary growing vegetables pattern and technology are changed and improve to the requirement of vegetables production.

Summary of the invention

In order to satisfy people to the non-harmful requirement of vegetables, improve the availability on booth vegetable ground, the utility model provides the non-pollution cultivation technique of a kind of vegetables, crops.

The present invention solves the technical method that its technical problem adopts: select not have the soil of industry " three wastes " as vegetable field, use sufficient fertilizer, select the broccoli kind of high yield, in the plantation and growth of broccoli, rationally execute inorganic fertilizer and agricultural chemicals, guarantee ripe broccoli high-yielding non-pollution.

Beneficial effect of the present invention is by the application that the present invention produces vegetables, to guarantee broccoli output height, vegetable grower's income raising.

Specific implementation method

Select kind Ru Qingfeng, the lining of good quality and high output green etc., its concrete culture technique is as follows:

The field seedling raising seedbed is chosen in high-land, be not subjected to waterlogging, irrigation and drainage are convenient, soil contains organic matter, the gutless in two years field piece of crossing brassicaceous vegetable.Ploughed deeply in 15-20 days before the sowing, before broadcasting 8-10 days every mu execute 20 kilograms of Nitrogen, Phosphorus and Potassium, 6 kilograms of superphosphate.Turn over to draw and harrow broken 1000 times of liquid controls of phoxim soil insect of using.Seed of handling and an amount of sand evenly are sprinkling upon on the seedbed, cover fine earth.Behind one deck sunshade net, put up little shed if will tile summer, covering one deck sunshade net, carry out the bilayer covering and preserve moisture, lower the temperature and grow seedlings; Grow seedlings with one deck mulch film, one deck canopy film and straw screen or mat double-layer heat insulation winter, takes off the lid in daytime straw screen or mat day.After emerging, throw off the film or the sunshade net of tiling, keep temperature 20-25 ℃ daytime, 12-18 ℃ of evening, aeration-cooling more than 30 ℃.Thinning is 1-2 time during 1-2 sheet true leaf.When 3-4 sheet true leaf, to divide seedling 1 time; Do wet situation according to soil between nursery stage and water, seedling is not generally applied fertilizer, and can suitably topdress according to the growth of cereal crop seedlings, carries out top dressing with potassium dihydrogen phosphate.

Field planting in good time is when seedling age about 30 days, the field planting of seedling 3-4 sheet true leaf.Before the field planting, execute 1200 kilograms of the fertilizers that become thoroughly decomposed, 30 kilograms in urea for every mu, 40 kilograms of 30 kilograms of potassium sulphates of diammonium phosphate, 100 kilograms in cake fertilizer are ploughed deeply to put in order and are carefully hugged flat bedding, the wide 1.4-1.6 rice of furrow, and every ridge cultivation 2 row, distance between rows and hills is 70 centimetres X30 centimetre., plant the 2400-2900 strain for every mu.Water sufficient seedbed water before the field planting, so that lifting.

The field management broccoli generally carries out topdressing for 3 times.Execute tiller fertilizer behind the transplant survival, water with rare human excrement urine of 10%-15% and execute; The beginning fertilizers for potted flowers imposes the compound useless 25-30 kilogram of potassium sulphate for every mu; Bouquet forms every mu of phase and with potassium dihydrogen phosphate 200 grams water spray more than 50 kilograms, sprays 1 time every 10 days, sprays altogether 2 times.The seedling-protection that will water after broccoli is transplanted survives suitably control water of back, and growth middle and later periods predry will be irritated, and pre-waterlogging will be arranged, and the field is ponding not, keeps the soil equilibrium moistening.Broccoli will carry out cultivation and banking 1-2 time before grave mound, Feng Hanghou does not intertill, but has weeds to remove with hand-lifting, in time send soil behind the torrential rain.The common insect pest of broccoli has aphid, diamond-back moth, tomato moth and Liriomyza etc., during control with 40% happy these 1000 times of liquid.The common disease of broccoli has damping off, bacterial slimy soft rot.Damping off can be killed to such an extent that 800 times of spraying controls were sprayed 1 time in general 5-7 days with 500 times of liquid sprayings of 50% carbendazim control, bacterial slimy soft rot with 70%, continuous use 2-3 time, and disease can be controlled.Note suitable period harvest at last.

Claims

1. the present invention relates to a kind of culture technique of vegetables broccoli, it is characterized in that: select not have the soil of industry " three wastes " as vegetable field, use sufficient fertilizer, select the kind of high yield broccoli, in the plantation and growth of broccoli, rationally execute inorganic fertilizer and agricultural chemicals, guarantee ripe broccoli high-yielding non-pollution.
