Now in large agricultural markets, vegetables have to cross the no-harm bar. It is worth collecting the next set of practical practices, as many of them have been used for a year。
The choice of the species and the mouth is the key
Locally adaptable, productive and high-quality, insect-resistant and resistant varieties are selected on the basis of different seasons, while ensuring that other species are marketable. The choice of species against frosting, molluscs and white spots, the selection of israeli stone tomatoes, brits, and the marriage of eggplants to wood such as tolubam are effective in combating the three major diseases, while peppers are used for the prevention of disease。
(b) rationally arrange the entry, implement a rotational fallback and adjust the planting period to avoid a high incidence of pests. High crops, such as field tomatoes and peppers, are growing maize on the edges of the ravine, and the horning period leads to two generations of cotton bell bugs and pyrotechnics to lay their eggs, reducing the harm, and the corn cover is resistant to pepper hemorrhoids and acupuncture。
The birth chain depends on half the harvest
The nursery soil must be sterile, insect-free and weed-free, rich in organic, fully nutritious, water-preserving and permeable. 50 ml and 2 to 4 kg of water-sprayed bed soil per square metre, covered by thin film from 2 to 3 days to tan for 7 to 8 days; it is also possible to feed the soil with 6 to 4 insect-free soil and decomposed organic fertilizers and save the money for disinfection。
Pre-plant seeds are carefully screened and priority is given to 55 to 60 degrees of hot soup for 10 to 15 minutes, and the eradication of the endemic bacteria and eggs is much safer than chemical agents, and the treatment of seeds with chemical substances must be reasonable. In winter and spring, seedlings are grown from electro-thermal hotbeds, temperature-controlled wet precipitous disease, dead disease and root, high-temperature rooting, early seedlings are made, and strong seedlings are grown。
Fertilizer methods directly determine quality
No harmful vegetablesFertilizers must measure soil formulations, supported by organic and fertilizer, using as much as possible multiple compound fertilizers. Vegetables are short for long periods of time, with heavy and light fattening, one-time plating, concentrated in the first half of the long-term life, late-term suspension of fast-effect nitrogen fertilizer, soil fertility sustained by decomposing organic fats and deep-turning floors, and not just follow-up production to tie up the ground。
The application of nitrogen fertilizer must be stopped eight days before the harvest, and the accumulation of nitrate in leafy vegetables must be reduced, which is a hard indicator for market testing and, failing that, should not be expected to enter the bank. In combination with rational rotations, both reducing the source of the disease and improving the soil structure, the more alive and fatter the vegetable land, the sooner the harvest takes place, and the sooner the garden is cleared and the better the ground is prepared。
Environmental regulation makes the bug inoperable
The planting process makes full use of light, heat, water and gas, creating an environment conducive to the growth of vegetables that is not conducive to the occurrence of pests and pests by controlling temperature, managing humidity, ventilation and covering the light. It is easy for many vegetable farmers to lose sight of the heavy summer storms, the use of small arches to cover the sunnet to protect against storms, the timely drainage and flooding following storms, and the determination of irrigation water not to be contaminated and to avoid secondary contamination。
Warm and wetness is prone to early disease, late disease, asymptomatic disease, folate disease, anthrax disease, high-temperature drought, and aphid outbreaks of viral disease, with warmth and wetness contributing to the disease. The temperature and humidity will be phased in to increase the resilience of the plant along with the sunnet, and environmental conditions will be put in place。
Pest controlIt's important
Implementation of a preventive and integrated approach, giving priority to agricultural and ecological measures such as anti-disease varieties, rational rotation, clean fields and increased production of bacteria. The most stable multipronged effects are the prevention of multiple pests, the treatment of insects by fertilizers, the use of fungicides for fungicides, and the eradication of earth-borne insect eggs by solar and winter temperatures。
The choice of highly effective, low-intoxication and low-intoxication residuals when medications are necessary is not met, and there is a strong commitment not to do drugs and a reduction in the number and use. When the target is met, the medication is used in a timely manner, the application time is selected according to the pattern of infestation, the dose and number of times are distributed in the field, blind enrichment is prohibited, and the use of different agents alternately to prevent insect resistance is the bottom line。
The last step of the harvest transport is not loose
The leaves, residues and surrounding weeds are removed immediately after the pre-harvest harvest, and they are concentrated in deep burial or burning, cutting the source of the disease and not passing it down to the vegetables. Cleaning the fields in time for the harvest, destroying all the sick and sick branches and leaving the gardens free, is also a crucial step in preventing the accumulation of harmful substances in the environment and protecting the ecology of the areas。
Vegetables collected are strongly not immersed in sewage and transported without contaminated equipment. From the ground to the market, the last ring of sanitation was not secured, all the damage-free management in the first place was wasteful, and all the tests were to be carried back in bulk, with a year of hard work, so the end was not loose。
The thing that hurts most when you grow is what kind of pests and pests, and we'll talk about it together. If you think it's useful, send it to your gardener friend, so that more people can grow something safe。
