[0002] At present, the growth period of corn is one season in the north every year, and two seasons in the south. Due to the change of natural climate, there is still a certain period of time before the frost period after corn harvest. For this reason, seedlings are grown in advance, and the temperature in the greenhouse is used to reach the biological upper line of 11°C. The corn seedlings are in the greenhouse to generate effective active accumulated temperature. According to the field temperature can reach above 11°C, the corn seedlings are transplanted to the field. Reseeding around the corn roots or sowing in the middle of the corn stalks to achieve the second season after the first season of corn is fixed, there is no agricultural application of a planting method for replanting corn in agricultural corn planting. Therefore, farmland has not generated greater economic value in the production process

Embodiment Construction

[0005] The following is a further explanation of the planting method of re-sowing corn. The greenhouse seedlings are raised around April 1 in the Gregorian calendar every year. About 130mm, about Фl00mm in drums, filled with black soil, stacked black soil thickness of about 130mm, it takes about 5 days for seedlings to emerge from the soil surface, and the seedling temperature of the cotyledons on the soil surface in the greenhouse is ≥ II ℃ to reach the biological upper line and form effectively The active accumulated temperature is transplanted into the field with soil around May 1 of the Gregorian calendar, forming branches, forming flowers, flower buds, and sizing. The growth period is 84 days, and the active accumulated temperature of the whole growth period is 1700°C. The effective accumulated temperature will be formed around 6th April, and it will be harvested from April 6th to July 1st in the Gregorian calendar. The second season corn can be sown directly in the middle...

Abstract

The invention relates to a planting method for corn replantation. According to the technical scheme of the planting method for corn replantation, corn seedlings which mature early and are resistant to cold and drought are cultivated at first and transplanted to a field to be subjected to lateral root and main root branching and grain filling till mature, wherein the growth period of the corn seedlings is about 84 days, and the active accumulated temperature of the whole growth period is 1700 DEG C; the corn seedlings in the second season are replanted in the middles of the corn seedlings in the first season and can also be planted on the peripheries of roots of the corn seedlings in the first season, or are planted before the corn seedlings in the first season mature; and the corn seedlings in the second season have the characteristics of being resistant to high temperature, draught and air permeability, early mature, well developed in stem, high in barren tolerance and branchiness and quick in vegetative body growth and maturity, the growth period is about 84 days, and the active accumulated temperature of the whole growth period is 1700 DEG C. By means of the planting method for corn replantation, three seasons of corn production can be achieved in the south.

Description

technical field [0001] The invention relates to an agricultural planting method, in particular to a planting method for replanting corn. Background technique [0002] At present, the growth period of corn is one season in the north every year, and two seasons in the south. Due to the change of natural climate, there is still a certain period of time before the frost period after corn harvest. For this reason, seedlings are grown in advance, and the temperature in the greenhouse is used to reach the biological upper line of 11°C. The corn seedlings are in the greenhouse to generate effective active accumulated temperature. According to the field temperature can reach above 11°C, the corn seedlings are transplanted to the field. Reseeding around the corn roots or sowing in the middle of the corn stalks to achieve the second season after the first season of corn is fixed, there is no agricultural application of a planting method for replanting corn in agricultural corn planting...
