Abstract

A kind of cultivation technique of red leaf lettuce, its main feature is that including processes such as site preparation, ridging, nursery, transplant planting, management, it solves red leaf lettuce and is easy uneven emergence affected by environment under traditional cultivation cropping pattern, big seedling is uneven, seedling-slowing stage is long after transplanting, leaf strain undergrowth easily causes leaf rolling lopsided, and the later stage, more diseases were rotted.It plants and uses suitable for red leaf lettuce open country.

Description

A kind of cultivation technique of red leaf lettuce

Technical field

The present invention relates to vegetable cultivation field, specifically a kind of cultivation technique of red leaf lettuce.

Background technology

Currently, red leaf lettuce cultivation mode is：Using traditional native seedbed nursery, site preparation does bedding cultivation, and broad irrigation is watered, The management mode of artificial trench digging caving ＆ fertilizing, the disadvantage is that easily uneven emergence affected by environment, big seedling is uneven, delays after transplanting Seedling stage is long, leaf strain undergrowth, easily causes leaf rolling lopsided, and the later stage, more diseases were rotted.Red leaf lettuce High efficiency and high quality cultivation is brought Adverse effect.

Invention content

The present invention is to solve traditional red leaf lettuce cultural method, invents a kind of cultivation skill of red leaf lettuce Art.

Technical scheme of the present invention, special character include process：

1, site preparation ridging：It first ploughs, next spreads fertilizer over the fields base manure, then revolves ground, ridging, paving drip irrigation zone, covering film, and ridge is 16-20 lis high Rice, 85-90 centimetres of row spacing；

2, nursery：Turf, vermiculite, perlite are uniformly mixed in the ratio of 9-3-1 as matrix, the matrix mixed is packed into 128 hole hole trays are then placed in intelligent greenhouse and set per one, hole seed, carry out nursery；

3, transplant planting：When red leaf lettuce seedling grows to " three leaves are wholeheartedly ", it is transplanted to crop field, per ridge duplicate rows, 27-30 centimetres of spacing in the rows, Cave field planting is dug, and trains real surrounding soil, transplanting is unsuitable too deep, keeps base portion just flat with earth's surface, and pour Ding Gengen water in time；

4, water and fertilizer management：Keep certain soil moisture content（Soil moisture content 65-75%）, using drip irrigation moisturizing fertilizer when insufficient, after field planting 7-10 days pour seedling recovering waters chase after 5-8 kilograms of urea in conjunction with pour seedling recovering water per acre on the basis of using sufficient base manure（First time topdressing）, Into the rosette state, to be poured with ploughing generation, restrain the growth of seedlings in due course, root system is promoted to be grown to depth, the restraining the growth of seedlings time should rest in 8-10 days, take care It when leaf starts inclusion, should terminate to restrain the growth of seedlings, start watering, fertilizing, chase after 5-10 kilograms of N P and K punching fertilising per acre, into peak of growing season, Third time fertilizer is chased after in conjunction with watering, chases after 7-10 kilograms of 5 kilograms of urea, 5 kilograms of potash fertilizer or N P and K punching fertilising fertilizer per acre, after growth Phase wants suitable control to water, and combines the foliar fertilizers such as spray foliage-spray potassium dihydrogen phosphate, calcium chloride or other calcareous fertilisers.

Technique effect

The solution have the advantages that using above-mentioned technical solution, red leaf lettuce open country High efficiency and high quality cultivation may be implemented, it is this Cultivation mode can make seed sprouting fast, neat, uniform, and slow seedling is fast after transplanting, and field management water-saving saves fertile saving of labor, disease pest and weed It is few, and yield is high, quality is good.

Specific implementation mode

1, site preparation ridging：It first ploughs, next spreads fertilizer over the fields base manure, then revolves ground, ridging, paving drip irrigation zone, covering film, the high 16- in ridge 20 centimetres, 85-90 centimetres of row spacing；

2, nursery：Turf, vermiculite, perlite are uniformly mixed in the ratio of 9-3-1 as matrix, the matrix mixed is packed into 128 hole hole trays are then placed in intelligent greenhouse and set per one, hole seed, carry out nursery；

3, transplant planting：When red leaf lettuce seedling grows to " three leaves are wholeheartedly ", it is transplanted to crop field, per ridge duplicate rows, 27-30 centimetres of spacing in the rows, Cave field planting is dug, and trains real surrounding soil, transplanting is unsuitable too deep, keeps base portion just flat with earth's surface, and pour Ding Gengen water in time；

4, water and fertilizer management：Keep certain soil moisture content（Soil moisture content 65-75%）, using drip irrigation moisturizing fertilizer when insufficient, after field planting 7-10 days pour seedling recovering waters chase after 5-8 kilograms of urea in conjunction with pour seedling recovering water per acre on the basis of using sufficient base manure（First time topdressing）, Into the rosette state, to be poured with ploughing generation, restrain the growth of seedlings in due course, root system is promoted to be grown to depth, the restraining the growth of seedlings time should rest in 8-10 days, take care It when leaf starts inclusion, should terminate to restrain the growth of seedlings, start watering, fertilizing, chase after 5-10 kilograms of N P and K punching fertilising per acre, into peak of growing season, Third time fertilizer is chased after in conjunction with watering, chases after 7-10 kilograms of 5 kilograms of urea, 5 kilograms of potash fertilizer or N P and K punching fertilising fertilizer per acre, after growth Phase wants suitable control to water, and combines the foliar fertilizers such as spray foliage-spray potassium dihydrogen phosphate, calcium chloride or other calcareous fertilisers.
