# high-quality and well-written incentives #
The cuisine, which is the bead of a cross-flower vegetable, conquers the taste buds of countless predators with a platinum ball. Such seemingly weak vegetables have great resilience to the environment. Science-based planting times and methods allow the flower to flourish in four seasons。
I. Spring gardening: taking advantage of the early spring market
In the spring, planting takes place on the "three mornings" principle: early seeding, early planting, morning marketing. The north china region proposes to plant in mid-february a greenhouse den until the seedling grows to one centrifugal in three leaves (about 30 days) and the short window of the spring neck is seized for planting in time. The yangtze basin could be properly delayed until early march. The selection of seed-resistant varieties, such as "fifty-four days", is particularly critical at this time, not only to resist early springs and colds, but also to ensure that the florist is tight. Care is taken to build small arch sheds to prevent night cream and to keep the soil humid but to avoid black decay caused by water accumulation。
Summer gardening: breaking the code for high temperature cultivation
The may-june summer planting was a technical test. At this point, heat-resistant varieties such as "50 summer flowers" and "45 days of heat tolerance" are selected, with the use of accelerator cultivation combined with silver grey membrane cover and the use of reflectivity to reduce surface temperature by 5-8°c. Experiments at nanjing agricultural university have shown that the combined application of 0. 01 per cent of ethethrin after 6 p. M. In irrigation can increase the rate of transfer to 92 per cent. It is crucial to prevent the risk of the tremors, with the weekly application of lysergic prophylactics alongside the blue sticky plate. When a flower ball is 8 cm in diameter, it is fastened with leaves, which significantly increases the value of the commodity。
Iii. Autumn gardening: responsive culture wisdom
After autumn, august-september is the most suitable gold window for large areas of cultivation. Selecting medium- and late-lated varieties such as "autumn 70" and " winter spring 2" to be planted at 30 x 40 cm range. At this time, the focus is on controlling nitrogen fertilizer and increasing the application of potassium phosphorus to promote thawing. A study by the agricultural institute of shandong province showed that the application of 0. 3 per cent of potassium dihydrohydrophosphate + 0. 1 per cent of the mixture of borin on the side of the leaf could lead to a 23 per cent increase in the commercial rate of florist. The addition of a wormnet at the end of september can effectively protect against slashed night moths, with a flower ball of up to 18-20 cm in diameter at harvest in early november。
Winter gardening: challenging low-temperature farming art
The winter planting, which began in october-november, was a test of wisdom. The yangtze basin can use cold-resistant varieties such as the winter show, covering the double membrane + small arches before the frost to form the sandwich-preserve structure. Data from the beijing city agricultural technology extension station show that at a minimum temperature of 0°c at night, the increase in the energy of the roots of the field with decomposed cow dung is 47% higher than that of conventional treatment. When extreme temperatures are encountered, 5% amino-vagina can be sprayed to increase resilience. When the temperature rises in march of the following year, ventilating is done in a timely manner and in mid-april, the fist size of the ball can be harvested。
V. Development of production systems for the anniversary
A full-cycle production chain of "the city of early springs - the sunshine gap - autumn supply main - winter storage added value" is needed to achieve full-year supply. The focus was on breaking out of summer-preservation and winter-conservation technologies: pre-cooled treatment after summer harvests to extend shelf life; and winter combination of air-repacking to extend storage periods beyond 8 weeks. Real-time humidity control through the internet-based monitoring system, combined with integrated water fertilizers, can reduce the combined cost by 30 per cent and achieve an efficient model of an annual acre production exceeding 12,000 pounds。
