Abstract

The invention belongs to the field of agricultural plantation, and specifically relates to a tomato cutting seedling technology. The technology mainly uses annual new shoots of tomatoes for vegetative propagation and seedling growing. Tomato cutting seedling can preferably keep excellent characteristics of a variety, and seedling time is short, breeding is fast, fruit bearing is early, and yield is high. The tomatoes can come into the market 40-45 days ahead of time.

Description

Tomato cuttage raise seedling technique

Technical field

The present invention relates to a kind of tomato cuttage raise seedling technique.Belong to field of agricultural cultivation.

Background technology

Tomato seeds nursery, cost is high, and breeding time, process was long, yielded poorly, and cuttage and seedling culture is simple, and economical, output can improve 10%, early ripe, listing in 40-45 days ahead of time.

Summary of the invention

The object of the invention is to develop a kind of tomato cuttage raise seedling technique, it is characterized in that adopting annual shoot to carry out asexual multiplication seedling, maintain the good characteristic of kind preferably, seedling raise period is short, breeds fast, result early, remarkable in economical benefits.Its cuttage and seedling culture method is as follows:

1 nutritive cube prepares: add 1 part of decomposed manure by 2 parts without damage by disease and insect, the fertile garden mould of not planting solanaceous crops and mix and sieve, spray 200 mg/litre disinfecting solution of potassium permanganate, add superphosphate 1 kilogram in every cubic metre of Nutrition Soil, ash 5 ~ 10 kilograms is mixed thoroughly, load in nutritive cube, put on seedbed, water permeable.

2 cuttings are collected: the plant good growth potential, premunition is strong is selected anosis, sturdy, dark green leaf color, internode are short, long 15 ~ 20 centimetres, have that 4 ~ 5 joints, growing point are intact, band bud but the side shoot of not blooming makes cuttage branch.

3 cuttings prepare: remove bottom big leaf's slice, retain 3 ~ 4, middle and upper part blade, the part of 3 ~ 4 centimetres, branch lower end are immersed 0.3% potassium dihydrogen phosphate and 0.2% urea mixed solution and soak after 2 ~ 3 hours to be inserted with clear water flushing.4 nutritive cube cuttages: first with pointed card punch insert 3 ~ 5 centimetres dark, then by the bottom of cutting patchhole, compacting cutting surrounding soil.

5 insert rear management: take Small plastic shed immediately after cuttage, covered with sunshade net, with insulation, moisturizing and shading, shading rate is advisable with 70% ~ 80%, forbid ventilating, canopy temperature to remain on 25 ~ 30 DEG C daytime, night remains on 17 ~ 18 DEG C, and ground temperature remains on 18 ~ 23 DEG C, and relative air humidity remains on more than 90%.After 5-7 days cuttage seeding start to sprout adventive root, sooner or later covering can be opened, suitable increase light application time and intensity, appropriate ventilation, canopy temperature to remain on 25 ~ 28 DEG C daytime, night remains on 15 ~ 17 DEG C, ground temperature remains on 18 ~ 23 DEG C, every spray in 5 ~ 7 days 0.1% ~ 0.2% potassium dihydrogen phosphate.After cuttage 15 days, the new root that branch lower end sprouts 5 ~ 7 more than 5 centimetres entered into seedling stage with during many adventive root, now can manage according to the management method of field run plant.

Claims

1. a technique for raising tomato seedlings by cutting is characterized in that it adopts tomato side branches to directly insert seedlings.

2. according to claim 1 described tomato lateral technique cutting seedling raising technology, it is characterized in that its method and condition are as follows:

(1) Nutrient bowl preparation: Mix 2 parts of fertile garden soil that is free from diseases and insect pests and has not grown solanaceous crops, add 1 part of decomposed organic fertilizer, mix and sieve, spray 200 mg/liter potassium manganate solution for disinfection, and nutrient soil per cubic meter Add 1 kg of calcium superphosphate, 5-10 kg of plant ash, mix well, put it into a nutrient bowl, place it on the seedbed, and water it thoroughly; (2) Collection of cuttings: on plants with good growth potential and strong disease resistance Select disease-free, strong, dark green leaves, short internodes, 15-20 cm long, 4-5 nodes, intact growth points, and flower buds but not bloomed side branches as cuttings; (3) Cutting preparation: remove For the large leaves in the lower part, keep 3 to 4 leaves in the middle and upper parts. Immerse the 3 to 4 cm lower part of the branches in a mixture of 0.3% potassium dihydrogen phosphate and 0.2% urea for 2 to 3 hours, then rinse with clean water and wait for insertion; ( 4) Cuttings in nutrient bowls: first use a pointed hole puncher to insert 3 to 5 cm deep, then insert the cuttings into the bottom of the hole, and compact the soil around the cuttings; (5) Management after cuttings: build a small shed immediately after cuttings, cover The sunshade net is used for heat preservation, moisturizing and shading. The shading rate should be 70% to 80%. Ventilation is prohibited. The relative humidity of the air should be kept above 90%. After the adventitious roots grow, the cover can be uncovered sooner or later, the light time and intensity should be increased appropriately, and ventilation should be done properly. At 18-23°C, spray 0.1%-0.2% potassium dihydrogen phosphate solution every 5-7 days. 15 days after cutting, 5-7 new roots of more than 5 cm will sprout from the lower ends of the branches.
