Abstract
The invention discloses a method for improving disease resistance of black tomatoes though a grafting method, belongs to tomato grafting methods, and aims to provide a grafting method for improving disease resistance of the black tomatoes. The method comprises the steps that rootstock seeds and scion seeds are cultivated, and the rootstock seeds are sown three to four days before the scion seeds are sown; seedling exercising can be conducted when seedlings grow to meet the conditions that the height ranges from 8cm to 10cm, and the stem diameter ranges from 0.3cm to 0.4cm, and then transplantation and field planting are conducted; strong rootstock seeds are selected one day in advance, and enough water and carbendazim are sprayed; the scion seeds are grafted onto the rootstock seeds through a splitting insertion grafting method, and the situation that each scion seed and 4-6 rootstock seeds are grafted together is guaranteed; grafting healing management is conducted according to a conventional method, and grafting clamps can be removed after new leaves grow on scions. According to the method, the grafting cost is greatly reduced, the occurrence rate of diseases such as the bacterial wilt disease, the canker disease, the fern leaf disease and the late blight disease is reduced substantially, the yield per mu can be increased by 33-55%, and the method is used for improving disease resistance of the black tomatoes.
Description
Technical field
The present invention relates to a kind of method for growing tomatoes, particularly relate to a kind of black tomato grafting method.
Background technology
Black tomato has another name called black tomato (Black Tomato), originates in South America; Be the treasure of tomato family, gain the name because its fruit is reddish black.Its fruit dietotherapeutic, has strong fruit aroma and the mouthfeel of moderately sour and sweet, is particularly suitable for eating raw; It contains a large amount of Lycopenes and abundant Vitamin C and antioxidant, is of high nutritive value.
Black tomato has very high commodity value, main based on traditional growing nursery and culture at present; Because its bad adaptability, diseases and insect pests resistance are weak, it is lower therefore to plant survival rate.In addition, owing to planting year after year, the damage by disease and insect such as bacterial wilt, canker, ferm-leaf, late blight are day by day serious, and cause black tomato drought resisting, cold-resistant, disease-resistant, insect resistance capacity sharply declines, rice shoot lethality reaches 50-70%.
Application number is " 201010103749.0 ", name is called a kind of method that patent document discloses by grafting tomato root-knot nematode resistant and TY virus of " grafting method of tomato ", although the method has certain enlightenment effect to the black tomato resistance against diseases of raising; But this patent not only grafting procedures is loaded down with trivial details, and an ingraftment seed can only obtain a strain grafting plant, thus causes that black tamato seed consumption is comparatively large, planting cost is high, is difficult to apply.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide a kind of method that grafting improves black tomato resistance against diseases, the method is simple to operate, planting cost is low, and the resistance against diseases that can significantly strengthen damage by disease and insect such as bacterial wilt, canker, ferm-leaf, late blights, improve output.
To achieve these goals, the present invention is by the following technical solutions:
1) rootstock seedling and scion seedling are cultivated: be seeded on nutrient matrix by stock seed, ingraftment seed, cover with vermiculite or Nutrition Soil, vermiculite or Nutrition Soil are covered with mulch film; Wherein, stock seed is early than ingraftment seed sowing in 3 ~ 4 days;
2) seedling management: seedling rearing room temperature to control daytime 28 ~ 32 DEG C, night controls, at 18 ~ 22 DEG C, after coming up, to remove mulch film, can carry out hardening, then transplant planting when the paramount 8 ~ 10cm of growth of seedling, stem thick 0.3 ~ 0.4cm; During hardening seedling rearing room temperature to control daytime 22 ~ 26 DEG C, night controls at 12 ~ 14 DEG C;
3) grafting, carries the rootstock seedling choosing height of seedling 10 ~ 12cm, the thick 0.4 ~ 0.5cm of stem, 4 ~ 5 cotyledons the previous day, sprays permeable and carbendazim; Within second day, cut rootstock seedling cotyledon with upper part, the cane of rootstock seedling is cut open; Cut the top of scion seedling and be whittled into wedge taper, then inserting in the cane groove of rootstock seedling, fix with Grafting clip; The cotyledon cutting scion seedling by described point of method again after the regeneration of scion seedling cane grows cotyledon one by one grafting, on other stock, ensures that every strain scion seedling and 4 ~ 6 strain rootstock seedlings carry out grafting;
4) grafting management, carries out field management during grafting callus according to a conventional method, can remove Grafting clip after spike length waiting goes out young leaves.
In technique scheme, described stock seed is wild tamato seed, and ingraftment seed is Dutch black tomato clock.
The preferred technical solution of the present invention is: described stock seed is with " No. one, look row " or " No. one, Japan ".
Compared with the prior art, the present invention is owing to have employed technique scheme, and with wild tomato seedling for rootstock seedling, therefore the affinity of rootstock seedling and scion seedling is strong, callus is effective, the callus cycle is short.Due to wild tomato plant well developed root system, climate adaptability is strong, disease resistance good, therefore significantly can strengthen the cold-resistant drought-enduring adaptability of grafting plant, the resistance against diseases of grafting plant can be increased substantially again, improve grafting plant survival rate and black tomato production.In addition, split slotting grafting method owing to have employed, the contact area of rootstock seedling and scion seedling therefore can be made to double, improve the survival rate of grafting plant.Because a strain scion seedling can carry out grafting with 4 ~ 6 strain rootstock seedlings; Therefore saved ingraftment seed, reduced grafting cost (stock seed price is well below ingraftment seed price), for the black tomato of implant mass provides possibility.Planting experiment shows, and adopt the inventive method to plant black tomato, the disease incidence such as its bacterial wilt, canker, ferm-leaf, late blight can decline 95%, 100%, 90%, 70% respectively, and per mu yield can increase income 33 ~ 55%.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described:
Embodiment 1
1) rootstock seedling and scion seedling are cultivated: in seedling-cultivating tray, prick the dark depression of a 0.5 ~ 1cm, place mat nutrient matrix in this depression, by stock planting seed on nutrient matrix, ensure that radicle is downward; The vermiculite thick with 1cm or Nutrition Soil cover, then vermiculite or Nutrition Soil are covered with mulch film; Ingraftment seed is sowed as stated above after 3 ~ 4 days;
2) seedling management: seedling rearing room temperature to control daytime 28 ~ 32 DEG C, night controls, at 18 ~ 22 DEG C, after coming up, to remove mulch film, can carry out hardening, then transplant planting when the paramount 8 ~ 10cm of growth of seedling, stem thick 0.3 ~ 0.4cm; During hardening seedling rearing room temperature to control daytime 22 ~ 26 DEG C, night controls at 12 ~ 14 DEG C;
3) grafting, carries the rootstock seedling choosing height of seedling 10 ~ 12cm, the thick 0.4 ~ 0.5cm of stem, 4 ~ 5 cotyledons the previous day, sprays permeable and carbendazim; Within second day, cut rootstock seedling cotyledon with upper part, the cane of rootstock seedling is rived from top to bottom; Cut the top of scion seedling and be whittled into wedge taper, then inserting in the cane groove of rootstock seedling, fix with Grafting clip; Until scion seedling cane regeneration grow cotyledon after again by described method cut respectively scion seedling cotyledon and one by one grafting on other stock, ensure that every strain scion seedling and 4 ~ 6 strain rootstock seedlings carry out grafting;
4) grafting management, carries out field management during grafting callus according to a conventional method, can remove Grafting clip after spike length waiting goes out young leaves.
