CN104380982A - Open field high-quality efficient cultivation technology for purple oilseed rapes - Google Patents

Abstract

The invention provides an open field high-quality efficient cultivation technology for purple oilseed rapes. The open field high-quality efficient cultivation technology is characterized by comprising the process of carrying out soil preparation, ridging, culturing seedlings, transplanting and planting, managing and the like. According to the open field high-quality efficient cultivation technology, the problems that the purple oilseed rapes are easily influenced by the environment under a traditional cultivation and planting pattern, the seedling emerging is not uniform, the rejuvenation period is long after transplanting, the growth of leaves and plants is not good, the crimping and deformation of the leaves are easy to cause, and the purple oilseed rapes are susceptible to diseases and are rotted are solved. The open field high-quality efficient cultivation technology is suitable for planting the purple oilseed rapes in an open field.

Description

One main laver heart open country High efficiency and high quality cultivation technology

Technical field

The present invention relates to growing vegetables field, is a main laver heart open country High efficiency and high quality cultivation technology specifically.

Background technology

At present, laver heart cultivation mode is: adopt traditional native seedbed nursery, do bedding cultivation, broad irrigation is watered wholely, the management mode of artificial trench digging caving & fertilizing, its shortcoming be easily affected by environment emerge uneven, large seedling is uneven, and after transplanting, seedling-slowing stage is long, leaf strain undergrowth, easily cause leaf rolling deformity, later stage many diseases are rotted.Adverse effect is brought to laver heart High efficiency and high quality cultivation.

Summary of the invention

The present invention is the technical problem solving traditional laver heart cultivation method existence, invents a main laver heart open country High efficiency and high quality cultivation technology.

Technical scheme of the present invention, its special character comprises process:

1, whole ground ridging: first plough, next spreads fertilizer over the fields base manure, then revolves ground, ridging, paving irrigate band, covering film, ridge height 16-20 centimetre, row spacing 85-90 centimetre;

2, nursery: the peat composed of rotten mosses, vermiculite, perlite are mixed as matrix in the ratio of 9-3-1, the matrix mixed is loaded 128 hole dishes, and one, every hole seed, then puts into intelligent greenhouse and sets, carry out nursery;

3, transplant planting: when laver heart seedling grows to " three leaves wholeheartedly ", be transplanted to land for growing field crops, every ridge duplicate rows, spacing in the rows 27-30 centimetre, digs cave field planting, and trains real surrounding soil, and transplanting should not be excessively dark, makes base portion just put down with earth's surface, and waters normal root root water in time;

4, water and fertilizer management: keep certain soil moisture content (soil moisture content 65-75%), adopt drip irrigation moisturizing fertile time not enough, 7-10 days pour seedling recovering waters after field planting, on the basis using sufficient base manure, chase after urea 5-8 kilogram (first time topdresses) in conjunction with pour seedling recovering water every mu, enter the rosette stage, to water with cultivated generation, in good time restraining the growth of seedlings, root system is impelled to grow to depth, the restraining the growth of seedlings time should rest in 8-10 days, when lobus cardiacus starts inclusion, restraining the growth of seedlings should be terminated, start watering, fertilizing, every mu chases after N P and K punching fertilising 5-10 kilogram, enter peak of growing season, third time is chased after fertile in conjunction with watering, every mu chases after 5 kilograms, urea, 5 kilograms, potash fertilizer or the fertile 7-10 kilogram of N P and K punching fertilising, to suitably control to water at later stages, and combine spray medicine foliage-spray potassium dihydrogen phosphate, the foliage fertilizers such as calcium chloride or other calcareous fertilisers.

Technique effect

Technique effect of the present invention is, adopts above-mentioned technical scheme, can realize laver heart open country High efficiency and high quality cultivation, this cultivation mode can make seed sprouting fast, neat, even, and after transplanting, slow seedling is fast, and field management water-saving economizes fertile saving of labor, disease pest and weed is few, and output is high, quality better.

Embodiment

1, whole ground ridging: first plough, next spreads fertilizer over the fields base manure, then revolves ground, ridging, paving irrigate band, covering film, ridge height 16-20 centimetre, row spacing 85-90 centimetre;

2, nursery: the peat composed of rotten mosses, vermiculite, perlite are mixed as matrix in the ratio of 9-3-1, the matrix mixed is loaded 128 hole dishes, and one, every hole seed, then puts into intelligent greenhouse and sets, carry out nursery;

3, transplant planting: when laver heart seedling grows to " three leaves wholeheartedly ", be transplanted to land for growing field crops, every ridge duplicate rows, spacing in the rows 27-30 centimetre, digs cave field planting, and trains real surrounding soil, and transplanting should not be excessively dark, makes base portion just put down with earth's surface, and waters normal root root water in time;

4, water and fertilizer management: keep certain soil moisture content (soil moisture content 65-75%), adopt drip irrigation moisturizing fertile time not enough, 7-10 days pour seedling recovering waters after field planting, on the basis using sufficient base manure, chase after urea 5-8 kilogram (first time topdresses) in conjunction with pour seedling recovering water every mu, enter the rosette stage, to water with cultivated generation, in good time restraining the growth of seedlings, root system is impelled to grow to depth, the restraining the growth of seedlings time should rest in 8-10 days, when lobus cardiacus starts inclusion, restraining the growth of seedlings should be terminated, start watering, fertilizing, every mu chases after N P and K punching fertilising 5-10 kilogram, enter peak of growing season, third time is chased after fertile in conjunction with watering, every mu chases after 5 kilograms, urea, 5 kilograms, potash fertilizer or the fertile 7-10 kilogram of N P and K punching fertilising, to suitably control to water at later stages, and combine spray medicine foliage-spray potassium dihydrogen phosphate, the foliage fertilizers such as calcium chloride or other calcareous fertilisers.
