High-impact cultivation techniques in the zhongchang province
In order to further optimize the structure of the city's vegetable growing varieties, enrich the citizens' “basket” and increase their choice to buy vegetables, as well as increase the efficiency of farming, and increase the productivity of farmers, the chauzhou centre for agricultural science and technology development introduced new varieties of guacamole from guangzhou acacia in january 2017 to be tested for the demonstration of guacamole, which is a highly popular type of winter melon. The fruit is close to circular and weighs 1. 5 to 3. 5 kg, it has wool and a little wax powder, it is green, it's thick, it's soft, it's soft, it's cooked and it's a natural taste of tara, and it's a unique species of winter melon, and it's popular among consumers. According to daejeon, the varieties are highly resistant, heat-resistant, adaptable, high-yielding and high-quality, and produce more than 3,000 kg. The main elements of efficient cultivation techniques for this variety are summarized below。
1 sowing in due course
It's a good time for the zhongdong region, january to february and july to august. The time of spring is a suitable early start to the first half of january, facilitating early harvests and longer harvest periods, during which time market prices are relatively high and the economy is more efficient. In autumn, not later than mid-september, too late seeding is vulnerable to low-temperature weather in the middle and later stages of growth, resulting in slow growth, low levels of melons and a halving of production。
2. Cultivating seedlings
Cultivation of fat leaves, green leaves, thick stasis and well-developed, age-appropriate seedlings is the key to productivity. Spring seedlings are in winter, prone to cold weather, and can be covered with small arc film. Autumn seedlings are at high temperatures and during the rainy season, and can be grown in the form of small arch sheds covering the top membranes and covering the sunnets to effectively cover the sun, cool and storm rain。
2. 1 leaching seedlings
Seeds are tanned 1 to 2 d before seed is planted, promoting seed preparation and increasing germination. The seed is then burned with hot water, with 15 mins in 55°c water, which is constantly mixed with hot water, and 2 h with 30°c warm water so that the seed is fully drained and the asphalted seed surface is watered. Seeds can be sprung to the white seed。
2. 2 seeding
In order to ensure that the seedlings grow well, the soil should have sufficient nutrients to supply the seeding period and have good water conservation and air permeability. The self-saturated soil mixes organic fertilizers, earth and fine sands at a ratio of 3:5:2 (the organic manure is to be fully decomposed, plus 1 kg compound fertilizer per cubic metre), and the three ingredients above are to be sifted and evenly mixed proportionally, with a ratio of 1:100 mixed into 50% of the enzymes or polyglyclytic powder, which can be dispersed when the water in the trophic soil is held by hand in groups and dropped from 30 cm high. A well-prepared field is fed into the nursery, which is selected for 50 holes. One grain per lacuna, seeds flatten or sprouts up, so as to reduce the "hat" seedling and then cover the nutrients of 1. 0 cm thick. The seedbed follows the north-south route to make a luminum, 15 cm or so, and is 1. 2 m wide, each 1 m by which a small piece of bamboo (approximately 2 m) is inserted into the earth and is circulated with a thin membrane and sunnet。
2. 3 shrimp management
Before seeding, especially during the fall, the temperature is high, the evaporation is high, and the water is expected to go out sooner or later, but not with too much water, so as to prevent the seeding of rotten roots, to maintain the relative humidity of 60 to 80 per cent of the soil and the treatment of 23°c to 28°c. Powder disease, which is mainly a pesticidal leaf, leaf handles and tubers, can be treated with 10% ether acetylene 800 times liquid spray。
5. 2 pests
The main pests in the cinnamon are the masts, aphids, white lice, peckles, guacamole flies, etc. Aphids, aphids, white lice can fly blue and yellow viscos under the shed, and the drug can be used to prevent the selection of 5 per cent aphids, 25 per cent aphids, 22 per cent aphids ethyl ester 1,000 to 1,500 liquid sprays; zephyr can be used 75 per cent of the wet powder for the fly 1,500 times; zephyr flies can be used to control the spray; zephylls can be used under the sheds with the yellow viscos with sexual inductions, and pharmacological control can be used in the initial selection of needle plume 800 times sprays, 5-7 d and 2-3 continuous spraying。
6 collection
Timely collection is a guarantee of efficiency. At the time of harvest, it is possible to collect guacamole of appropriate sizes at the request of the client, or, if used as cucumber, 30 d after the fruit, or 1. 5 kg of cucumber, or 40 d after the fruit. It's usually collected in the morning, cut in two cm with a twig, light and light, and avoid harm to melons and melons, so that they can be stored. The cinnamon is more resilient, with long shelf periods, kept in a ventilated, cold environment for three to six months, suitable for long transport。
