CN104365350A - High-quality and high-efficiency cultivation technology for lettuces in open field - Google Patents

Abstract

A high-quality and high-efficiency cultivation technology for lettuces in an open field is characterized by comprising the processes of land preparation, ridging, seedling culture, transplantation, field planting, management and the like. The high-quality and high-efficiency cultivation technology solves the problems that the lettuces are easily influenced by the environment, seedling emergence and seedling sizes are uneven, the seedling recovery period is long after transplantation, leaves and plants grow badly, blades are prone to curling and deformation, and diseases and rotting are caused in a later period in a traditional cultivation and planting pattern. The high-quality and high-efficiency cultivation technology is suitable for planting of the lettuces in the open field.

Description

A kind of Lettuce open country High efficiency and high quality cultivation technology

Technical field

The present invention relates to growing vegetables field, is a kind of Lettuce open country High efficiency and high quality cultivation technology specifically.

Background technology

At present, Lettuce 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 Lettuce High efficiency and high quality cultivation.

Summary of the invention

The present invention is the technical problem solving traditional Lettuce cultivation method existence, invents a kind of Lettuce 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 Lettuce 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 Lettuce 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 Lettuce 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.
