The technologies used to grow the plastic sheds include, inter alia, the selection of varieties, seedlings, planting, field management, pest control and harvesting. The plastic shed early soybean cultivation techniques are summarized below。
Premature, high-quality, high-yielding varieties should be selected, with the following main varieties: violet beans, peanuts beans, soybeans one。
The seedlings are grown using a greenhousely nutritious seedling。
1. The planting period is generally in the southern region in mid-march and in the northern region in mid-march and late. The seeding rate is 4-5 kg per 667 m2 of shifting fields and 100 g per square metre of seed beds. The soil of the seedling beds must be more than 80 per cent watery at the time of seeding, and the soil temperature of the warm indoor bed must remain above 12°c. Temperature 20-25°c during the day and 15-16°c during the night. The seeding is carried through the bottom water, which, after leaking, is used to sow 3&mdash4 sprouts of seed, 1. 5 cm of soil, and then to button small arches。
The preparation before seeding includes three main aspects。
(1) production of seeding beds and formulation of nutrients
The size of the seed beds in the greenhouses should be determined according to the size of the greenhouses, and the nutrients should be placed in the nursery beds. (b) nutrient soil formulation: 60 per cent of the field, 30 per cent of the decomposition organic fertilizer, 10 per cent of the decomposition manure, and then evenly mixed root tumours, long-acting microbes. The well-equipped soil is then fed into a nutrition column of 8 cm or 10 cm in diameter and 12 cm high。
(2) when seed treatment is carried out, the choice is made to immerse the 1% ff solution for 20 minutes in order to kill the anthrax on the surface of the seed and wash it with water。
(3) 2 & mdash three days before seeding 3 & mdash 4 hours before immersion, 24 hours below 30 °c, so that the root can break the skin。
3 when seeding occurs, the temperature of the seed season and the management of the moisture rises to the seeding point, 20-25°c during the day, 15-16°c during the night, 3&mdash four days after the arch is flattened and the membrane cooled. 15 & mdash 20 °c in the daytime, 10 °c in the day after the birth of the seed, 10 °c in the daytime, 10 °c in the daytime, 20 & mdash 25 °c in the daytime for the lumbering and rooting of the leaf, 10 days in the daytime, 15 & mdash 20 °c in the daytime, 12-15 °c in the night. In water management, due to the drought-resilient nature of the green bean seedlings, an appropriate 2&mdash 3 times, with neither drying nor wetting, after the seedlings are produced, depending on their strength and soil moisture。
Slender standards, well-trained sprouts, small and well-established roots, 2&mdash3 leafs, 30&mdash 35 days。
1. Pre-plant preparation
(l) ground-based fertilisation is selected for flat, sun-to-earth plots, with 45 & mdash60 tons of organic fertilizing per hectare, and then tilling the land for fertilisation。
(2) the 20 & mdash 25-day shack, usually in mid-march, was built in the 2 & mdash shack, which uses a drop-free anti-aging membrane membrane and a polyethylene plastic membrane capacity of 120 kg per 667 m2。
2. Plantation
(l) temperature indicators for the planting of safe seasons and temperature-conservation measures, when beans are planted in large sheds, must be stabilized at 10°c or above, at no less than 8°c at night, usually in mid-april. Temperature protection at the time of planting: internal temperature protection is used in huts with shacks and double curtains, and, if necessary, in sheds with warmer stoves, while external temperature protection is used mainly in the surroundings of the sheds with weeds。
(2) plantation methods and densities range from 30 cm*60 cm in length to 8,000 cm in length & mdash1000 cm in size, chicken beans typically grow with a width of 1. 2 cm in width, with two rows per acre, 20 & mdash25 cm in length, 6,000 & mdash8,000 in length, and chicken seeds can also be associated with green vegetables such as oil and vegetables, high tungsten cultivation, and 1 m in width, with a distance of 25 cm in length in length and a distance of 10 cm in length in three rows in the row, and with a drop of chickens. When they are planted, they pour water out of their ditches, so that the soil may be wet, then they will be covered with dry soil。
1 post-plant management to pre-opening bouquets
(1) after planting the seedlings, china shall sow the soil so that the soil may be decompressed so as to contribute to the warming of the land and to the growth of the root system, usually every other week, from the time of planting until the flowering. China must be deep, and as it tilles, it should grow to its roots. It's been a long time since i've been able to get to the top。
(2) temperature management after planting of temperature and moisture management is maintained at 20-25°c during the day, at 15 & mdash20°c at night, at about 20°c during the flowering period and above 15°c at night, in order to facilitate normal flowering. In water management, the ability of beans to withstand drought is such that water is not used to fertilize from planting to flowering, in order to prevent long leaves. When flowers start to bloom, the amount of wind is increased to remove humid air for pollination, avoid flowers and reduce disease。
(3) when the chicken seed is taken out of the penis by 30 cm, a pair shall be made up, two rows shall be grown together with adult frames, and one row shall be planted with a frame or human frame。
Management of the closing period
(1) the fatty management of the short-breed beans, when they are presented with buds, then the chickens start to be followed up by fat-filled water to promote the rapid growth of the platinum. Illustrated ammonium phosphate at 225-300 kg/ha, 7-10 days of water, not too much water per day, 10 & mdash 15 days of chicken seed, 2 & mdash 3 times of fertilizer, 150 - 225 kg of phosphate per day. Embezzlement or spraying of americ acid with 0. 01-0. 03 per cent. Early ripening and early production can be promoted。
(2) ventilation is managed by ventilation, which generally does not take place within a week of planting to keep the shed warm so as to facilitate the smoothing of seedlings. When temperatures exceed 30 °c, ventilation should be provided at short notice at noon and should be maintained at around 25 °c from the slow seedling to the flowering period in order to promote growth, and the flowering turquoise period should remain at around 20 °c, with a large wind volume, which would facilitate pollination, condensation and fattening of the berries. High temperatures and high humidity can cause flowers to fall, which should be kept at 75 per cent, and the wind should go down day and night after the final frost。
1. The disease prevention and treatment season can be used to prevent ashilosis, red spots, anthrax and 5 per cent of ashilosis and anthrax with 600 times the amount of rusty cortex for 2000 & mdash 3,000 times。
2. Pest control animals use 1,000 & mdash 1,500 times 40% fruit for aphids and 40% asyre or 3,000 & mdash 4,000 times as fast for aphids, gland night moths, aphids and red spiders for long periods of time。
The bean is fed by green beans, which are collected when they reach the maturity of the commodity. The harvest began 25 to 35 days after the planting of the common dwarfs, 35 & mdash 45 days after the planting of the chickens, 3 & mdash harvested once in 5 days and 1 & mdash harvest in 2 days during the styling season. The late harvest of the quality of the impact and the subsequent chords, the harvest of which is on the market in a timely manner, can be preserved at 3°c。
It is necessary to clear the fields in a timely manner. Stay focused and burn. In the early part of july, the maggot was collected. The bars shall be centrally stored to prevent the second year of the pest egg on the strain and to combat pests。
