Maitiro eKuvandudza Watermelon Fruit Setting Rate uye Kudzivirira Michero Kudonha?

Boka rekutanga remavise muchirimo rinogadzira michero nekukurumidza, rinokura nekukurumidza, uye rinoraira mutengo wakakwira. Zvisinei, kusagadzikana kwemamiriro ekunze kwemvura kunoita kuti kugadzika kwezvibereko kuve kwakaoma, zvichiita kuti pave nengozi yakawanda yekudonha kwemichero. Kuvandudza chiyero chekumisikidza michero uye kudzivirira kudonha kwemichero ndicho chinhu chinonyanya kukosha kune varimi vewatermelon.

I. Chii chinonzi Watermelon Fruit Drop?

Kudonha kwemuchero weWatermelon zvinoreva kusamira kwekukura kwechibereko muchirimwa, kutanga nechikamu chepamusoro chemuchero mudiki zvishoma nezvishoma chichishanduka yero nekusvava, zvichizoguma nekudonha kwemichero.

II. Zvikonzero zveWatermelon Fruit Drop:

1. Kutadza kwemaruva echikadzi kutakurwa nekuiswa fetiraiza mushure mekutumbuka. Manwiwa zvirimwa zvine maruva akasiyana echirume neechikadzi. Kana nguva yemaruva ichienderana nekunaya kwemvura, pollen inotora unyoro uye kuputika; kana kana pane zvipembenene zvishomanana zvinosvibisa, maruva echikadzi haakwanisi kusvibiswa zvakanaka, kudzivirira ovary kubva pakuwedzera uye kukura kazhinji, zvichiita kuti iwire.

2. Zvisizvo munhengo yeruva remukadzi kana murume. Semuyenzaniso, rusarura rwakanyanya kupfupika, kusavapo kwemajita emuto, kushaikwa kwekugadzirwa kwepollen muanthers, kana kupera kwepistil zvinogona kukonzera kudonha kwemuchero wewatermelon.

3. Zvose zvakanyanyisa uye zvisina simba kukura kwemiti kunogona kukonzera kudonha kwemichero. 4. Hunyoro hwevhu husina kuenzana panguva yemaruva. Mvura yakawandisa inokonzera kukura kwezvinomera zvakanyanya, zvichiita kuti maruva echikadzi ave nekushaya zvokudya zvinovaka muviri uye zvichiita kuti michero ibvise pamuviri. Mvura isina kukwana inoita kuti muti udonhe maruva nekuda kwekushaya mvura.

5. Mamiriro ezvinhu ezvakatipoteredza asina kunaka. Tembiricha yakanyanyisa kana kuti yakadzikira panguva yekutumbuka inokanganisa pollen chubhu kurebesa, zvichiita kuti maruva asakura zvakanaka uye kudonha kwemaruva. Chiedza chisina kukwana chinotadzisa photosynthesis, zvichiita kuti ovary itambure kwenguva pfupi nekushaya zvokudya zvinovaka muviri uye zvichiita kuti michero ibvise pamuviri.

6. Kusaenzana pakati pekukura kwezvinomera uye kubereka. Kunyanya kukura kwezvinomera kunogona kutungamirira kukukura kusina kunaka kwemaruva echikadzi uye kubvisa pamuviri kwemichero.

7. Kuwandisa. Kuwandisa kunotungamirira kuurombo husina chiedza uye kukura kwezvinomera zvakanyanyisa, izvo zvinokanganisa kukura kwekubereka uye kuita kuti michero iome.

8. Kukuvadza kunokonzerwa nezvipembenene nezvirwere.

III. Nzira dzekudzivirira nekudzora kubvisa nhumbu yemuchero wewatermelon:

1. Artificial pollination.
1. Munguva yemaruva emvura, tora maruva echirume pakati pe7 ne10 am, bvisa corolla, uye shandisa zvakafanana stamens yemaruva echikadzi. Isa ma stamens kune 2-3 maruva echikadzi paruva remurume. Bata zvinyoro-nyoro panguva yekumesa kudzivirira kukuvadza kusarura.

2. Ronga nguva yekudyara zvine hungwaru, uchiona nguva yekumisikidza michero yemavise inodzivirira mwaka wekunaya kwemvura kuitira kuti mukume uenderere mberi. Ipa akakodzera mamiriro ezvakatipoteredza embeu panguva yembeu kusimudzira kusiyanisa kwemaruva uye kuderedza mukana wemaruva akaremara.

3. Isa fetereza nemvura nesainzi.
Isa inorema base fetereza usati wadzvara, kunyanya organic fetireza, inowedzerwa nekukurumidza-kuita nitrogen, phosphorus, uye potassium fetereza. Deredza kuisa nitrogen fertilizer zvakakodzera panguva yekukura kwemuzambiringa uye maruva. Tevedzera misimboti yefetiraiza uye kudzora kudiridza zvakakodzera kuti uve nechokwadi chekukura kwakasimba uye kudzivirira zvakanyanya kukura kwezvinomera.

4. Chengetedza kukura kwemuzambiringa wakawandisa kuderedza kudya kusingakoshi.

5. Dyara pane density inonzwisisika kuti uve nechokwadi chekufefetedza uye kupinda kwechiedza.

6. Kuchekerera uye kuchekerera panguva yakakodzera: Kuchekerera hakungogadzirisi kukura kwezvinomera uye kuberekana asiwo kunonatsiridza kupinza mhepo nekupinza kwechiedza. Mushure mekugadzirwa kwemichero, kusungirirwa panguva yakakodzera kunoisa kugovera kwekudya, kukurudzira kukura kwemichero.

7. Uchishandisa zvinodzora kukura kwechirimwa: Pazuva rinovhurwa ruva remukadzi kana kuti zuva rakapfuura, pfapfaidza bud remuchero ne0.1% Forchlorfenuron. Pfaya zvakaenzana kumativi ose emuchero. Kazhinji, patembiricha iri pasi pe18°C, shandisa inenge 10ml ye0.1% Forchlorfenuron yakadirwa mu1.5kg yemvura; pa 18-24 ° C, shandisa 10ml yakasvibiswa mu 1.5-2kg yemvura; uye pa25-30 ° C, shandisa 10ml yakasvibiswa mu 1.5-3kg yemvura. Izvi zvinosimudzira kugadzirwa kwemichero uye kunowedzera chiyero chemichero.

8. Kuwedzera nekutsvaga zvinhu kunowedzera kutapira uye ruvara, kunodzivirira maruva nemichero, kunokurudzira kukura kwezvibereko nekukura, uye kunowedzera goho.

9. Kudzivirirwa nenguva kwezvipembenene nezvirwere.
