Pumpkin spring Open to Hybrid Technology

. Within the farming system can not grow around the 250Om other summer squash varieties, in order to prevent natural hybridization. Before colonization 15d, each 667m2 of facilities by the full maturity of organic manure 5000kg, DAP 55kg, potassium 50kg, 50% carbendazim WP 1kg, blending evenly applicator on the ground, broken up deep plowing after smashing 30 fine -40cm, Baping ground, made the flat stretch of 1.3m wide and covers a good film. 2. Pumpkin Seed is different from the rational close planting vegetable cultivation cultivation, selection for seed cultivation leaving only 1-2 per plant melons, all the rest of Guatiao Thinning, accompanied by playing the right to adjust the technology thinning plants and flowers, so close planting should be appropriate . 45cm of spacing when planting in the film by playing larvae L,[link widoczny dla zalogowanych], plant 2 rows of each plot of every 3 rows planted a line of male female parent to facilitate pollination. 667m2 of the total colonization of 2300 parents. Huanmiao pouring enough water after planting, transplanting and then fine soil around the larvae L sealed. 3. Man of the management of extension (1 Song strain adjusted after planting to flowering stage,[link widoczny dla zalogowanych], should focus on raising seedlings, and promote vegetative growth, this should be sufficient supply of water, and promptly destroyed the maternal side branch, completely erase the maternal and paternal male female flowers in order to reduce unnecessary consumption and to prevent the string of nutrition powder mixed germplasm occurs. (2 fan pest control aphids during this period is what occurs when a large area, special attention should control aphids in order to avoid virus, resulting in plants failure, affect the seed yield and quality. III. pollination 1. emasculation May mid-pollination, usually lasts about 7d. before the female flowers open in the female should be removed all the male bud, later checked every 4-5d 1 to grow out of the new female male, female male flowers must be removed completely clean, otherwise it will affect the purity of hybrids, leading to hybridization failure. 2. artificial pollination male squash flower early, and the pollen is not high temperature, at 24-25 �� temperatures above the short will lose its vitality, it must be artificial pollination in the flowering of a 9:00 on the same day as soon as possible. artificial pollination of removing the male parent is male, remove the calyx, pedicel holding the anthers of stamens have been cracking light Light applied to the female stigma of female flowers, pollination, when the action to light, but also to evenly spread the pollen, usually a male female flower can be granted 2-3. 1-2 melons per plant to remain, strong growth potential of plants can also be choose to stay three, depending on the female plants may be growing field. IV. Jhonggua the management of an expanding period. removal of hybrid male and to generally be the last one you reap what you plant after pollination, 3-5d, there is no sign of melon , melon and gradually began to expand when the male pulled out plants,[link widoczny dla zalogowanych], air and light can effectively improve the status of the field, reduce nutrient consumption, improve seed production rate of a single melon. pollination after the end of 10-15d, to check from time to time and strictly to the complex, time will appear on female plants and several non-hybrid melon with you reap what you entered the expanding period after pollination. here should strengthen the fertilizer and water management, water to g, while 7-10d 1 photosynthetic spraying fertilizer or Atonik foliar fertilizer, etc., to promote full seed. 3. pest control work of this period is still very important to control aphids, the choice of 10% imidacloprid WP 1000 times for spraying. diseases are viral diseases, powdery mildew, downy mildew, can be 20% of the virus were selected WP A 500 times or 1.5% Ling EC 1000 times Plant Pathology,[link widoczny dla zalogowanych], Agricultural Water resistant 120 dose rate of 500 times or 12.5% Poly 500 times, 64% of the anti-virus alum WP 600 times or 58% WP Metalaxyl MZ 600 times spraying.. five. harvested from the pollinated the end of the melon harvest generally takes about 40-50d. When hard squash skin melons, golden color, plant decline significantly when the melon is the full maturity. melons harvested, placed in cool air, the emission layer by layer well, allowed to fully mature after about 10d to increase grain weight of seed. but not too long after the ripening time should not, otherwise the seed will germinate in Guatemala. In general, hard seeds and flesh out the stick and wrapped in membrane separation After ripening therefore, can be melons away with, will be placed with the seed of the flesh dug earthenware containers, under the conditions at 20-30 ��, 16-24h after fermentation, the seeds into a more dense nylon bag to rub. washing, separating the seeds and pulp thoroughly, then rinse, dry time on the mats on the water content of less than 7% to toss out flat tablets, pellets for storage. the general quality can be produced per 667m2 40 Hybrid -6okg so.
