the following work is completed after the first year in autumn and before the first year in autumn, namely before the irrigation in autumn:

firstly, herbicide is beaten on stubble fields, base fertilizer is spread, ploughed fields are leveled and rolled, and then autumn soaking is carried out;

after the farmland is thawed in the early period of spring ploughing in the second year, fertilizing, ploughing and pesticide spraying are started; grinding and paving the film according to the condition of the amount of cultivated land and grass, namely performing full mulching film coverage;

the interval time between the sowing time and the dibbling time is 12 days to 15 days, the grassy bud and the lettuce bud under the mulching film are poisoned or stacked to lose life under the high-temperature sealing of the mulching film in the time, and the weeding effect is optimal.

The invention further adopts the technical scheme that mechanical seed manure application and full-film covering are started after the farmland is thawed for fifteen centimeters;

and after the film is laid, dibbling and sowing are started, so that the operation can be carried out for fifteen to eighteen days in advance, the purpose of fruiting is to improve the ground temperature in advance, weed is removed in advance, the weeding effect is good, the injury to crops is small, the rape blooms in the middle and middle ten days of June at the beginning of June, and enters the fruiting period at the beginning of June, the high-temperature and arid weather can be avoided at the beginning of June, the flowering period is normal and sufficient, and the fruiting period is a high-yield fruit.

A further technical solution of the present invention is that,

the method for applying pesticide to the stubble land before ploughing in the autumn and the autumn further comprises the following steps:

the herbicide is prepared with trifluralin emulsion in 48 wt%, and through spraying 150-180 ml of water and 35-40 kg of water to autumn field, and spreading after plowing, grinding and rolling.

The film is paved by a positive black film with the thickness of 0.1mm, the whole film is adopted for covering, no gap can be formed between the films, the overlapping part of 5 cm-8 cm is required, and uniform Qileng covering pressure is used for preventing weeds from growing out at the gap, so that all weed seeds in and on the soil are killed by poison in bud embryos or the germinated seedlings are killed by suffocation or poison at the closed high temperature below the black film, and the weeding effect is achieved.

Compared with the prior art, the invention adopting the technical scheme has the following beneficial effects: the method creates the application of the full-film mulching overwintering early sowing technology for the rapes for seed production, avoids the influence of high-temperature and arid weather after the middle ten days of July, realizes the purposes of early sowing, early flowering and early harvesting and stable yield increase, realizes the change of planting habits and plays a positive guiding role in improving the planting benefit.

Drawings

To further illustrate the present invention, further description is provided below with reference to the accompanying drawings:

FIG. 1 is a flow chart of the invention;

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and detailed description, which will be understood as being illustrative only and not limiting in scope.

The hybrid rape seed production field and the rape planting Gansu Qinghai are generally in the first ten days of April, the first blooming of July is Xinjiang in the first to middle ten days of May, the middle blossom of July is blooming to the middle ten days of August, the high-temperature drought in northern weather is generally concentrated in the middle ten days of July to middle ten days of August, the hybrid rape seed production field and the rape planting method generally suffer from high-temperature drying climate in the full-bloom stage, the flowering phase is shortened, the fruiting is less, the silique is short, the seeds are few, the yield of rapeseeds is seriously influenced, in order to reduce and avoid the repeated occurrence of the phenomenon, the seeding is carried out in advance, the dibbling is started after the cultivated land in spring is thawed, and the tasks of dibbling and sowing can be completed in about the first 3 months.

The key step for realizing early sowing (10 to 15 days ahead) and sowing is to soak in autumn after autumn (irrigation in autumn),

the following work is completed: the method comprises the steps of firstly spraying base fertilizer on stubble fields (herbicide), flatly leveling and rolling ploughed fields, and then soaking in autumn, so that after October in the first year finishes the work, when the second month is from the bottom to the beginning of the third month in the second year, mechanically fertilizing (fertilizing) and mulching (full mulching) is started after the ploughed fields are thawed for fifteen centimeters, dibbling and sowing are started after the mulching is finished, so that the operation can be carried out for fifteen to eighteen days in advance, the fruiting aims of improving the ground temperature in advance, weeding is carried out in advance, the weeding effect is good, the injury to crops is small, the full flowering period in the middle ten days of the sixth month is achieved in the early sixty month of rape, and the fruiting period is achieved in the early seventy month, the high-temperature dry weather can be avoided, the flowering period is normal and sufficient, and the fruiting period is a high-yield fruit.

1. Pesticide application attention of stubble fields before ploughing after autumn: 1. the dosage of the herbicide is increased by 20-25% compared with the normal dosage (marked on a medicine bottle), 48% of trifluralin emulsifiable concentrate is selected for herbicide selection, 150-180 ml of the herbicide is uniformly sprayed on a autumn harvest after harvest by adding 35-40 kg of water per mu, and then the film is paved after plowing, grinding and rolling. 2.
